[PATCH v2 0/7] uapi: export all headers under uapi directories

[PATCH v2 0/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v2 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory.
The patch 6 was spotted by code review: there is no in-tree user of this
functionality.
The last patch remove the use of header-y. Now all files under an uapi
directory are exported.

asm is a bit special, most of architectures export asm/<arch>/include/uapi/asm
only, but there is two exceptions:
 - cris which exports arch/cris/include/uapi/arch-v[10|32];
 - tile which exports arch/tile/include/uapi/arch.
Because I don't know if the output of 'make headers_install_all' can be changed,
I introduce subdir-y in Kbuild file. The headers_install_all target copies all
asm/<arch>/include/uapi/asm to usr/include/asm-<arch> but
arch/cris/include/uapi/arch-v[10|32] and arch/tile/include/uapi/arch are not
prefixed (they are put asis in usr/include/). If it's acceptable to modify the
output of 'make headers_install_all' to export asm headers in
usr/include/asm-<arch>/asm, then I could remove this new subdir-y and exports
everything under arch/<arch>/include/uapi/.

Note also that exported files for asm are a mix of files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/x86/include/uapi/asm/Kbuild;
 - arch/x86/include/asm/Kbuild.
This complicates a lot the processing (arch/x86/include/asm/Kbuild is also
used by scripts/Makefile.asm-generic).

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. I don't know if it should be
made against antoher tree.

Comments are welcomed,
Nicolas

Moving the file is correct as far as I can tell, but the extra
#include is not necessary here, as the kernel will automatically
search both arch/arm/include/ and arch/arm/include/uapi/.

The same applies to patches 2 and 4.

Indeed, I'd like to see the include/asm file gone.

This one is only a redirect to an asm-generic header, so it can be
removed completely and replaced with a line in the 
arch/nios2/include/uapi/asm/ file:

generic-y += setup.h

It should rather not be exported - please remove it from
arch/x86/include/uapi/asm/Kbuild instead.

Thanks.

Just hint for the future:

[PATCH v2 5/7] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that unput-files3-name is genhdr-y.

[PATCH v2 7/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-unicore32/shmparam.h
asm-unicore32/ucontext.h
asm-hexagon/shmparam.h
asm-mips/ucontext.h

I'm pretty sure these should not be exported!

Those files are created in every directory:
$ find usr/include/ -name '\.\.install.cmd' | wc -l
71
$ find usr/include/ -name '\.install' | wc -l
71

That still does not mean they should be exported.

Anything but headers (and directories as a skeleton structure) is maximally suspicious.

What I was trying to say is that I export those directories like other are.
Removing those files is not related to that series.

Perhaps the correct solution is to only copy files matching "*.h" to
reduce the risk of copying files incidentally created by kbuild but
which shouldn't be installed as uapi headers.

This is interesting, though not your problem. Maybe someone who understands
cris better can comment on this: How is the decision made about which of
the arch/user.h headers gets used? I couldn't find that in the sources,
but it appears to be based on kernel compile-time settings, which is
wrong for user space header files that should be independent of the kernel
config.

I don't know if anyone still uses "make headers_install_all", I suspect
distros these days all use "make headers_install", so it probably
doesn't matter much.

In case of cris, it should be easy enough to move all the contents of the
uapi/arch-*/*.h headers into the respective uapi/asm/*.h headers, they
only seem to be referenced from there.

For tile, I suspect that would not work as the arch/*.h headers are
apparently defined as interfaces for both user space and kernel.

The series should probably get merged through the kbuild tree, but testing
it on mainline is fine here.

I believe it's since the CRISv10 and CRISv32 are very different beasts,
and that is selected via kernel config...

This part of the CRIS port has been transformed a couple of times from
the original layout without uapi, and there's still some legacy silliness,
where some files might have been exported but never used from userspace
except for some corner cases.

[PATCH v3 0/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v3 of this series. The first 5 patches are just cleanup: some
exported headers were still under a non-uapi directory or (x86 case) were
wrongly exported.
The patch 6 was spotted by code review: there is no in-tree user of this
functionality.
Patches 7 and 8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me ;-)

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

I'm taking this patch, but with the following commit log:

  Due to the way kbuild works, this header was unintentionally exported
  back in 2013 when it was created, despite it not being in a uapi/
  directory.  This is very non-intuitive behaviour by Kbuild.

  However, we've had this include exported to userland for almost four
  years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
  no hint that anyone has complained about it.  So, let's make it
  officially exported in this state.

If anyone has any objections, they better shout sooner rather than
later.

[PATCH v3 3/8] nios2: put setup.h in uapi

[Nicolas Dichtel]

This header file is exported, but from a userland pov, it's just a wrapper
to asm-generic/setup.h.

[PATCH v3 5/8] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v3 7/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-unicore32/shmparam.h
asm-unicore32/ucontext.h
asm-hexagon/shmparam.h
asm-mips/ucontext.h

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

[PATCH v3 8/8] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

These weren't defined by the kernel before, so why do we need to define them
now?

Will defining __UINTPTR_TYPE__ cause problems in compiling libboost by
changing the signature on C++ functions that use uintptr_t?

It is listed in include/uapi/asm-generic/Kbuild.asm, which is included by
arch/arm/include/uapi/asm/Kbuild.

You can also have a look at patch #5 to see why it was exported even if it was
not in an uapi directory.

I mentioned it to David, and he says it's because the long list of
recipients is breaking his mailer.  I've already posed the question

We really should not be installing non-uapi header files to userland
under _any_ circumstance - this to me sounds like a bug in kbuild.

The assumption is that headers outside of uapi directories are not
part of the user visible API, and so can be freely modified - which
in the presence of this bug is untrue.

However, as it's happening, and this header has been there since 2013
(commit 09096f6a0ee2 - "ARM: 7822/1: add workaround for ambiguous C99
stdint.h types") it's now well and truely part of the user API whether
we intended it to be or not, so your patch looks to me like the correct
thing to do.

I think it needs further evaluation to make sure kbuild isn't going to
do something else silly, like subsitute include/asm-generic/types.h for
the now missing arch/arm/include/asm/types.h

I wonder how many more headers are unintentionally exported.

... what a mess. :(

It's not (or was not) a bug exactly - it was something introduced in commit
10b63956fce7f369cc37fd4d994f09bd5203efe4 to ease the transition to using the
UAPI headers as Linus required the commit for each header dir to go through
the submaintainer's tree.

It was supposed to be removed, but that never got posted to Linus because t=
he
next phase of cleanups didn't happen as Linus said he block my email and ne=
ver
take any more patches from me if I sent him any more:-/

> -header-y += msr-index.h

I see it on my desktop as /usr/include/asm/msr-index.h and it's been there at
least four years - and as such it's part of the UAPI.  I don't think you can
remove it unless you can guarantee there are no userspace users.

I keep it in the v2 of the series, but the maintainer, Borislav Petkov, asks me
to un-export it.

I will follow the maintainer decision.

I'm not the maintainer. I simply think that exporting that file was
wrong because it if we change something in it, we will break userspace.
And that should not happen - if userspace needs MSRs, it should do its
own defines.

[PATCH v4 0/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v4 of this series. Seems there was too many people cc'ed, so I've
removed arch specific ml. Hope it's better now.

Patches #1 to #4 are just cleanup: some exported headers were still under
a non-uapi directory.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patches #6 and #7 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

Why? Why is this damn thing exported in the first place?

The moment we decide to change an MSR name or even remove it from that
file, we break userspace. And what for, because userspace is using some
arbitrary header file which was meant to be for the kernel solely.

It is exported because it is listed in arch/x86/include/uapi/asm/Kbuild:
header-y += msr-index.h (see also patch #4).

I understand your concerns but my patch does not change anything. And I think
David's comment is right: if I remove it, I break the uapi.

After digging a bit, it seems you have already tried to remove it in commit
b72e7464e4cf ("x86/uapi: Do not export <asm/msr-index.h> as part of the user API
headers"), but because this file is still listed in the Kbuild file, it is still
exported.

It would be great if we could find a consensus about what to do with this file
because it blocks patch #4 and the rest of the series.


Thank you,
Nicolas

Oh great. :-\

The reasoning in b72e7464e4cf was valid then and is valid now. This
thing should not have been exported in the first place. And it's not
like I didn't try then. Dammit!

I know, we should not ever break userspace but if it were me, I'd remove
that export and see what breaks. If at all.

But let's see what the others think first.

Or keep the exported version as-is and never changed it, and use
a different copy for the kernel itself.

Yeah, that's a good idea, thanks Christoph.

I guess we'll have to do that if something in userspace has put its
sticky fingers on that file and cannot be fixed. Which I hardly doubt
but we can't break that damn userspace.

The importance of uapi headers presence is a bit overrated.

If you look at, for example, iptables (and further projects in that 
area), copies of uapi headers have been made (and this process is likely 
to continue) because it could be compiled on a variety of vintage 
systems that do not have all required #defines yet.

Similarly, it may be built on a variety of _modern_ systems whose 
kernels no longer have a particular thing (e.g. ipt_SAME), so it also 
ships copies of those headers.

So if some userspace component depends on that particular msr header (which,
unlike ipt_SAME, was not intended for export), is it not reasonable to expect
them to make a copy if and when they need it?

Yeah, either copy the whole header or better yet use own defines.
Especially in this particular case, where we have a bunch of MSRs which
are in the processor manuals. Exporting the defines is pretty pointless
and even disadvantageous for the kernel.

So do you agree with the current patch (a build-fix is also needed :/)?

$ less /usr/include/asm/msr-index.h
#ifndef _ASM_X86_MSR_INDEX_H
#define _ASM_X86_MSR_INDEX_H

/* CPU model specific register (MSR) numbers */

/* x86-64 specific MSRs */
#define MSR_EFER                0xc0000080 /* extended feature register */
#define MSR_STAR                0xc0000081 /* legacy mode SYSCALL target */
#define MSR_LSTAR               0xc0000082 /* long mode SYSCALL target */
...

Like it or not, it is _already_ exported to userspace, so it forms
part of the user ABI.  You can try to remove it from userspace view,
but if anyone has already started to use it, removing it will already
cause a userspace regression.

So, I don't think we have any grounds to NAK these patches on the
basis of "we don't want this to be visible to userspace because it
may cause a userspace regression."  Removing it from userspace view
is likely to cause a userspace regression.

This patch just makes sure that such a regression doesn't happen when
kbuild stops exporting files in _non_-uapi directories.

Well, I did try to stop it then too:

  b72e7464e4cf ("x86/uapi: Do not export <asm/msr-index.h> as part of the user API headers")

And yet this wankery trickled out to userspace anyway.

Well, if it were me, I'd still remove the header and see if anything
breaks.

If it does - which I doubt very much - we can do Christoph's idea of
leaving the current version of the header exported but then untangling
it from the whole uapi crap and use our own kernel version which we can
change as much as we can.

In the end of the day, it is a maintainer decision what's going to
happen.

Yes, it was the only goal. My patch changes nothing!

Firstly, I believe you are (very!) confused about what forms part of the Linux 
user-space ABI - it's not the exported headers but the functionality and how 
application _binaries_ rely on it. We have strong ABI guarantees that are in no 
header anywhere. And we have tons and tons of details in UAPI headers that are not 
part of any system call ABI (or protocol ABI) of Linux.

Note that for example the 'MSR_STAR' definition you quote above is not part of the 
ABI, because user-space _cannot make use of it_: it's a privileged CPU register 
that only the kernel can write to. There's no system call ABI that Linux defines 
that this MSR (or any other MSR for that matter) are part of.

These MSR headers are not part of the ABI - they are part of the _mechanism_ 
trying to inform user-space about ABIs and people trying to somehow claim that 
they are an ABI are confused IMHO.

The point with msr-index.h is that there's no user-space ABI where those MSRs are 
enumerated.

Secondly, ABI means 'Application Binary Interface' - note the 'Binary' part. The 
ABI cannot be broken, by definition, by putting a header into another place. Now 
we do export UAPI headers and we definitely don't want to break user-space tooling 
if we can avoid it, but trying to spin the UAPI headers mechanism into an "ABI" is 
confused on so many levels.


I.e. this whole discussion is silly in the extreme. The point of the UAPI exports 
is to clean up our ABI exports, after we used to export _all_ headers to 
user-space.

I.e. by definition the UAPI mechanism is fundamentally about _restricting_ the 
amount of headers that are exposed - separating true ABI from random kernel 
internals. This process of enumerating ABI details separately from kernel 
implementation internal details improves the kernel headers.

> [...]  You can try to remove it from userspace view, but if anyone has already

I challenge you to show a single user-space regression from the removal of the 
'MSR_STAR' definition for example.

Please explain, why do you want to export msr-index.h and which part of it is an 
'ABI' in your opinion? Until you can explain that my NAK stands.

Thanks,

[PATCH v5 0/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v5 of this series. Seems there was too many people cc'ed, so I've
removed arch specific ml. Hope it's better now.

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patches #7 and #8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.

v4 -> v5:
  - patch #3: get back to v3 (don't export msr-index.h)
  - patch #6: new in this version
  - patch #7: fix compilation by introducing header-n

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v5 4/8] Makefile.headersinst: cleanup input files

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.

[PATCH v5 7/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h
asm-blackfin/ucontext.h

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

[PATCH v6 0/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v6 of this series.

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patches #7 and #8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.

FYI, I will be off for 10 days.

v5 -> v6:
  - patch #6: remove change of include/uapi/linux/media.h
  - patch #7: fix hdr export when 'make O=' is used (look for genhdr files in
              the right directory)
  - patch #8: fix 'make headers_check'

v4 -> v5:
  - patch #3: get back to v3 (don't export msr-index.h)
  - patch #6: new in this version
  - patch #7: fix compilation by introducing header-n

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v6 4/8] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v6 7/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

And for the third time: this is not related to this series. Those files are
there before my series and the goal of the series has nothing to do with that.

Your description literally says "After this patch, the following files, which
were not exported, are now exported (with make headers_install_all)"
for the files that Christoph quoted. It that is not true, then you need to
update the patch description to say what your patch actually does.

That is true. But as I explained when the comment was done the first time (and I
never got any answer), these files are generated in every exported directory.
Because the genwqe directory is now exported, the corresponding '..install.cmd'
and '.install' are generated.
See
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/Makefile.headersinst#n32
and
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/Makefile.headersinst#n130
for more details.

In other words, these files are there because some new directories are exported.
If those directories were added to the 'header-y' variable, the result would be
the same.

Nicolas

[PATCH v7 0/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Here is the v7 of this series.

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patches #7 and #8 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.
Michal, is this series going through your tree?

v6 -> v7:
  - rebase on last linus tree
  - patch #7: remove autogenerated files from the list in the commit log

v5 -> v6:
  - patch #6: remove change of include/uapi/linux/media.h
  - patch #7: fix hdr export when 'make O=' is used (look for genhdr files in
              the right directory)
  - patch #8: fix 'make headers_check'

v4 -> v5:
  - patch #3: get back to v3 (don't export msr-index.h)
  - patch #6: new in this version
  - patch #7: fix compilation by introducing header-n

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v7 1/8] h8300: put bitsperlong.h in uapi

[PATCH v7 2/8] nios2: put setup.h in uapi

[Nicolas Dichtel]

This header file is exported, but from a userland pov, it's just a wrapper
to asm-generic/setup.h.

[PATCH v7 3/8] x86: stop exporting msr-index.h to userland

[Nicolas Dichtel]

Even if this file was not in an uapi directory, it was exported because
it was listed in the Kbuild file.

[PATCH v7 4/8] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v7 7/8] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

Note that the following newly exported headers have userspace compilation
errors:

/usr/include/drm/armada_drm.h:26:2: error: unknown type name 'uint32_t'
  uint32_t handle;

/usr/include/linux/btrfs_tree.h:390:12: error: 'BTRFS_UUID_SIZE' undeclared here (not in a function)
  __u8 uuid[BTRFS_UUID_SIZE];

/usr/include/linux/cryptouser.h:58:16: error: 'CRYPTO_MAX_ALG_NAME' undeclared here (not in a function)
  char cru_name[CRYPTO_MAX_ALG_NAME];

/usr/include/linux/kfd_ioctl.h:33:2: error: unknown type name 'uint32_t'
  uint32_t major_version; /* from KFD */

/usr/include/linux/smc_diag.h:6:27: fatal error: rdma/ib_verbs.h: No such file or directory
 #include <rdma/ib_verbs.h>

/usr/include/linux/wil6210_uapi.h:73:2: error: unknown type name 'uint32_t'
  uint32_t op; /* enum wil_memio_op */

I think they should be fixed first.

Sure. Thanks for pointing this out. I will send a v8.

I'm still wondering if Michal will take this series or if it will go through
another tree.

[PATCH v8 00/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patch #7 to #9 fix some errors when the corresponding files are included by
userland.
Patches #10 and #11 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.
Michal, is this series going through your tree?

v7 -> v8:
  - rebase on top of linus tree
  - add patch #7, #8 and #9

v6 -> v7:
  - rebase on top of linus tree
  - patch #7: remove autogenerated files from the list in the commit log

v5 -> v6:
  - patch #6: remove change of include/uapi/linux/media.h
  - patch #7: fix hdr export when 'make O=' is used (look for genhdr files in
              the right directory)
  - patch #8: fix 'make headers_check'

v4 -> v5:
  - patch #3: get back to v3 (don't export msr-index.h)
  - patch #6: new in this version
  - patch #7: fix compilation by introducing header-n

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v8 04/11] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

Nack.  cryptouser is just one interface in the crypto API.  It
should not be included by every single crypto user in the kernel.

You could perhaps introduce a new file under uapi just for this.

[PATCH v9 00/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patch #7 to #9 fix some errors when the corresponding files are included by
userland.
Patches #10 and #11 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built against linus tree. If I must rebase it against the kbuild
tree, just tell me.
Michal, is this series going through your tree?

v8 -> v9:
  - rebase on top of linus tree
  - patch #8: add include/uapi/linux/crypto.h

v7 -> v8:
  - rebase on top of linus tree
  - add patch #7, #8 and #9

v6 -> v7:
  - rebase on top of linus tree
  - patch #7: remove autogenerated files from the list in the commit log

v5 -> v6:
  - patch #6: remove change of include/uapi/linux/media.h
  - patch #7: fix hdr export when 'make O=' is used (look for genhdr files in
              the right directory)
  - patch #8: fix 'make headers_check'

v4 -> v5:
  - patch #3: get back to v3 (don't export msr-index.h)
  - patch #6: new in this version
  - patch #7: fix compilation by introducing header-n

v3 -> v4:
 - first patch has been included
 - patch #4: get back to v2 and remove arch/x86/include/asm/msr-index.h

v2 -> v3:
 - patch #1: remove arch/arm/include/asm/types.h
 - patch #2: remove arch/h8300/include/asm/bitsperlong.h
 - patch #3: remove arch/nios2/include/uapi/asm/setup.h
 - patch #4: don't export msr-index.h
 - patch #5: fix a typo: s/unput-files3-name/input-files3-name
 - patch #6: no change
 - patch #7: fix include/uapi/asm-generic/Kbuild.asm by introducing mandatory-y
 - add patch #8

v1 -> v2:
 - add patch #1 to #6
 - patch #7: remove use of header-y

Comments are welcomed,
Nicolas

[PATCH v9 04/11] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v9 10/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

[PATCH v9 11/11] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

I'm a bit pushy on this, but it would be nice to get this series in before the
rc1. In fact, it would certainly be better to have this living some times in
-next, but it would probably generate a lot of conflicts in linux-next. OTOH
those conflicts would be easy to solve.

Nicolas

I will take care of this.

Michal's tree is not active these days.
Going forward, I will queue up Kbuild patches in my repository.



BTW, this series does not apply cleanly.

If you could rebase it onto v4.11-rc1 tag,
it would be helpful.



Thanks!

You really want this on top of 4.11-rc1 or the last linus tag, ie v4.11-rc2?

Basically, I queue up patches based on -rc1 tag
unless there is a particular reason for otherwise.

If it is based on -rc1, will it cause conflicts with Linus tree?

[PATCH v10 00/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patch #7 to #9 fix some errors when the corresponding files are included by
userland.
Patches #10 and #11 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built on top of masahiroy/linux-kbuild.git#for-next (v4.11-rc1).
I didn't find any conflict with v4.11-rc2.

v9 -> v10:
  - rebase on top of masahiroy/linux-kbuild.git#for-next
  - patch #4 & #10: fix dependency check
  - fix some typos in commits logs

Just a minor comment.

The include guard was originally __ASM_H8300_BITS_PER_LONG.
This will change it into _ASM_H8300_BITS_PER_LONG
(after _UAPI is stripped by headers_install.sh)

I just thought _UAPI__ASM_H8300_BITS_PER_LONG might be even safer,
but I know I am nit-picking.  I can apply this as-is.
I leave it to you.

I intentionnaly "clean" that, but I will restore it, no problem ;-)

[PATCH v10 04/11] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last three patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

Can you move <linux/types.h> below <linux/btrfs.h>
to sort the includes alphabetically?

This also applies to:

include/uapi/linux/qrtr.h in 06/11
include/uapi/linux/cryptouser.h  in 08/11

[PATCH v10 10/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

+
+	mandatory-y is essentially used by include/uapi/asm-generic/Kbuild.asm

[PATCH v10 11/11] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

Can you remove

arch/cris/include/arch-v10/arch/Kbuild
as well?

Or, not sure if they are still needed?

I don't think so. Have a look to 77c8006d8df4 ("UAPI: Fix up empty files in

As a whole, this series is amazing.  Thanks for your great work!


I added some comments, but they are trivial.




I wanted to leave comments/questions on 10/11,
but I could not find 10/11 in my mailbox.  I do not know why.


I am leaving comments on the cover-letter,
the following are related to 10/11.

What is this actually checking?

If ARCH has its own (uapi/)asm/{kvm.h,kvm_para.h,a.out.h},
they are added to mandatory-y, then they are checked if they exist.
But, we know they exist.


This check reminds us only when we added asm/*.h
but forgot to add uapi/asm/*.h

$(srctree)/arch/$(SRCARCH)/include/uapi/asm/$(hdr) seems unneeded at least.
(perhaps, the whole hunk might be unneeded.)

This series intends all headers are exported from uapi/, correct?
Do we still need to check $(srctree)/arch/$(SRCARCH)/include/asm/*.h ?
(related to [1])

Going forward, header-y will be never used
because uapi/ is exported by default.

So, I wonder if we could rename this into something clearer.

Kbuild supports "no-clean-files".
(Please see ./Kbuild for its usage)
I guess this notation seems clearer
when we want to negate the default behavior.

Can you consider "no-export", "no-export-files", "no-export-headers"
or whatever you like?




Thanks!

Yes, you're right. With english words : 'those files are mandatory only if they
exist', thus they are not mandatory at all :)

No you're right, uapi/asm/*.h is enough. Those files should be exported only if
the uapi/asm/ counterpart exists.

I took the patch from the patchwork for git-am,

[PATCH v11 00/12] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Patches #1 and #2 are just cleanup: some exported headers were still under
a non-uapi directory. Patch #3 is a fix to avoid exporting a file that was
not under an uapi directory.
After these three patches, all exported headers are under an uapi directory:
path #4 stops searching files in non uapi directories.
The patch #5 was spotted by code review: there is no in-tree user of this
functionality.
Patch #6 fixes some warnings/errors reported by 0-day tests.
Patch #7 to #9 fix some errors when the corresponding files are included by
userland.
Patches #10 and #11 remove the need to list explicitly headers. Now all files
under an uapi directory are exported.
Patch #12 is also a small cleanup.

This series has been tested with a 'make headers_install' on x86 and a
'make headers_install_all'. I've checked the result of both commands.

This patch is built on top of masahiroy/linux-kbuild.git#for-next (v4.11-rc1).
I didn't find any conflict with v4.11-rc4.

v10 -> v11:
  - patch #1: restore the double '_' in the header guard
  - patch #6, #7, #8: order '#include' in alphabetical order 
  - patch #10: rename header-n to no-export-headers
               cleanup management of kvm.h, kvm_para.h and a.out.h
  - patch #12: add it
  - rebase on top of masahiroy/linux-kbuild.git#for-next

v9 -> v10:
  - rebase on top of masahiroy/linux-kbuild.git#for-next
  - patch #4 & #10: fix dependency check
  - fix some typos in commits logs

v8 -> v9:

[PATCH v11 04/12] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last three patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

Can we revert this patch please? I had forgotten about it when
increasing the in-kernel CRYPTO_MAX_ALG_NAME so it now conflicts
with the crypto tree.  The crypto tree has fixed the problem in
a different way.

Thanks,

[PATCH v11 10/12] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

Re: [PATCH v11 10/12] uapi: export all headers under uapi directories

I will send pull-requests for v4.12 in a few days.

I need to fix a complex conflict reported by
https://lkml.org/lkml/2017/4/10/1208

I rebased linux-kbuild/uapi on commit 13e0988140
(dropping 08/12 "cryptouser.h: fix include from userland").


I updated the list of headers, which were not exported,
are now exported.

If you find something is wrong, please let me know.
The list is now as follows:

    asm-arc/ucontext.h

linux/vfio_ccw.h is missing in your list.
And to be a bit picky, linux/fsmap.h should be put before
linux/genwqe/genwqe_card.h ;-)

I've rebased my tree on commit 2868b2513aa7 (see
https://github.com/NicolasDichtel/linux/commits/master) and the following file
should also be added after that: linux/switchtec_ioctl.h.


Thank you,
Nicolas

[PATCH v11 11/12] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

Starting with commit 61562f981e92 "uapi: export all arch specifics
directories", a "make INSTALL_HDR_PATH=$root/usr headers_install"
operation will delete standard glibc headers and others in
$root/usr/include.

Here's the snippet from the build process where it deletes system
headers with this commit:

[PATCH v8 10/11] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h
asm-avr32/kvm_para.h
asm-blackfin/shmparam.h

Note that I have removed from this list the files which are generated in every
exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

[PATCH v8 11/11] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

[PATCH v6 8/8] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

[PATCH v4 4/7] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that input-files3-name is genhdr-y.

[PATCH v4 6/7] uapi: export all headers under uapi directories

[Nicolas Dichtel]

Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-unicore32/shmparam.h
asm-unicore32/ucontext.h
asm-hexagon/shmparam.h
asm-mips/ucontext.h
asm-mips/hwcap.h
asm-mips/reg.h
drm/vgem_drm.h

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

If these aren't just a mistake in your list the patches need to be
fixed not to install this build system internal file.

And I'm pretty sure I already pointed this out last time.

Yes, it was already pointed out. But, as I said, this is done for *every*
exported directory. My patch just follows how it is done currently:
$ find . -name '.install' | wc -l
105
$ find . -name '..install.cmd' | wc -l
105
$ find . -type d | wc -l
105

I'm not against removing these files, but this should be done in another patch,
it's not related to this series.
Fell free to send a patch.

Nicolas

[PATCH v4 7/7] uapi: export all arch specifics directories

[Nicolas Dichtel]

This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.
