Generic headers allow ARCH maintainers to remove all dummy
arch/ARCH/include/asm/XXX.h files or, depending on the architecture, 
include/asm-ARCH/XXX.h (e.g. arch/x86/include/asm/errno.h) that only 
include the _name equivalent_ include/asm-generic/XXX.h file 
(e.g. include/asm-generic/errno.h) with _no_ changes. It was called 
generic headers for short. Arnd Bergmann gave the original idea and 
asked me to implement it.

To use it just two steps are necessary:

 - Remove all the dummy arch/ARCH/include/asm/XXX.h files 
   (e.g. rm arch/x86/include/asm/errno.h)

 - Add the variable generic-y with the names of the removed files 
   (e.g. generic-y += errno.h) in the arch/ARCH/include/asm/Kbuild 
   (e.g. arch/x86/include/asm/Kbuild)

The removed files will be automatically generated during the build 
process by the script scripts/Makefile.genericheaders.

The scripts/Makefile.headersinst was adapted to avoid errors (due to 
the removal of header files from their default locations) so it would 
pass the 'make headers_check'.

The generic headers were applyed and tested in both x86 (tested in my 
Notebook with i386_defconfig on kernel 2.6.29-rc7 of 09/Mar/2009 from 
Linus git tree) and powerpc (tested in my PS3 with ps3_defconfig on 
kernel 2.6.29-rc7 of 11/Mar/2009 from Geoff Levand git tree). Both 
compiled and booted without problems.

This approach does not reduce much LOC but, in a rough estimation, it 
would allow the removal of around 90 dummy header files among all 
architectures.

PS: This is my first e-mail/patch here. Sorry for any misbehaviour :)

Create the infrastructure that allow ARCH maintainers to remove all
arch/ARCH/include/asm/XXX.h files or, depending on the architecture,
include/asm-ARCH/XXX.h (e.g. arch/x86/include/asm/errno.h) that only
include the _name equivalent_ include/asm-generic/XXX.h file
(e.g. include/asm-generic/errno.h) with _no_ changes. It was called
generic headers for short. Arnd Bergmann gave the original idea and
asked me to implement it.

To use it just two steps are necessary:

 - Remove all the dummy arch/ARCH/include/asm/XXX.h files
   (e.g. rm arch/x86/include/asm/errno.h)

 - Add the variable generic-y with the names of the removed files
   (e.g. generic-y += errno.h) in the arch/ARCH/include/asm/Kbuild
   (e.g. arch/x86/include/asm/Kbuild)

The removed files will be automatically generated during the build
process by the script scripts/Makefile.genericheaders.

NOTE: the arch/ARCH/include/asm/XXX.h (or include/asm-ARCH/XXX.h)
file can only be removed if it has the _exact same name_ as the
include/asm-generic/XXX.h file and _no_ additional logic.

Hi Remis.

I recall having exchanged mails with Arnd about the topic before but
I have lost track of it.

Why is it that we do not implment this using the following scheme:

Create a new directory:
1) include/generic/asm
2) Add the directory to the searchpath _after_ all ARCH supplied search paths.
3) Teach headers install about this new place
4) Move all generic headers from asm-generic to this new home
   and add a dummy "#include <generic/asm/foo.h>" in asm-generic

Then we can delete all the one-liners in $ARCH/include/asm
which simply include the asm-generic version.

Actually this is a much better solution. I just tried it out for few
files and it seems to work quite well. I will implement it and send
the patch.
But what do you think if, instead of creating the dummy "#include
<generic/asm/foo.h>" in asm-generic, we create symlinks?
I've heard about an "avoid-symlink policy" so it is more a sort of
question than suggestion ;-)

Generic headers allow ARCH maintainers to remove all dummy
arch/ARCH/include/asm/XXX.h files or, depending on the architecture, 
include/asm-ARCH/XXX.h (e.g. arch/x86/include/asm/errno.h) that only 
include the _name equivalent_ include/asm-generic/XXX.h file 
(e.g. include/asm-generic/errno.h) with _no_ changes. It was called 
generic headers for short. Arnd Bergmann gave the original idea and 
asked me to implement it. This is the second implementation with the 
changes proposed by Sam Ravnborg.

To use it just one step is necessary:

 - Remove all the dummy arch/ARCH/include/asm/XXX.h files 
   (e.g. rm arch/x86/include/asm/errno.h)

The scripts/Makefile.headersinst was adapted to avoid errors (due to 
the removal of header files from their default locations) so it would 
pass the 'make headers_check'.

The generic headers were applyed and tested in x86 (tested in my 
Notebook with i386_defconfig on kernel 2.6.29-rc8 of 17/Mar/2009 from 
Linus git tree). It compiled and booted without problems.

This approach does not reduce much LOC but, in a rough estimation, it 
would allow the removal of around 90 dummy header files among all 
architectures.

This patch is an update to the patch 'Create the infrastructure for
generic headers'.

The 'make headers_install' is copying the dummy header files from
include/asm-generic to the OBJTREE/usr/include/asm-generic. But these
dummy header files are pointing to their equivalents in
include/generic/asm which were not being exported. This could cause
problems in the compilatin of some user space applications.
This patch fixes this problem by also exporting the header files from
include/generic/asm to the OBJTREE/usr/include/generic/asm.
