[PATCH 00/15] Remove asm/segment.h from low hanging architectures

[PATCH 00/15] Remove asm/segment.h from low hanging architectures

[Kumar Gala]

The following set of patches removes the use and existence of 
asm/segment.h from the architecture ports that it was fairly trivial to do 
so.  I need to work with the arch maintainers on the following 
architectures since they use asm/segment.h heavily:

m32r
um
frv
h8300
i386
m68knommu
m68k
v850
x86_64

If any arch maintainers want to go a head kill asm/segment.h in that last 
I would be very appreciative.

Thanks

Did you already remove all the uses outside the parisc-specific bits of
the tree, eg ISDN, media/video/, sound/oss/, etc?

If so, ACK, otherwise, NAK.

I did remove them.  I should have included a reference to the patch

I posted a similar patch a month ago, but I only removed the
arch/ia64 includes of asm/segment.h.

There are still a few drivers that include asm/segment.h, so
I don't think we should remove asm/segment.h itself just yet.

Agreed.  The sequence should be to send patches to get rid of
all "#include <asm/segment.h>" references.

Once they have all gone, then a patch can remove the files.

If you are concerned that people would start adding new
references and you don't want to get into a game of whack-a-mole,
then you could add #warning "include of deprecated asm/segment.h",
but that might be overkill.

I'll apply this for ia64 w/o the deletion.

I've posted a patch before this to remove all non-architecture users  
of asm/segment.h.

Ok, so it sounds like my patch to remove drivers from include asm/ 
segment.h is fine, and we will leave it up to the various arch  
maintainers to decide if they want to keep asm/segment.h for arch  
specific usage.

This is now in my test tree.  I will send to Linus soon after
2.6.13 is released.

You've broken various things by doing this because some driver code
rightly or wrongly uses segment.h. That is fine because they shouldn't
do so. However asm/segment.h isn't supoosed to be removed on
architectures that use segments- like x86, and x86-64. There it is a
real arch private file and shouldn't be disappearing.

It shouldn't be leaking into drivers any more (eg mxser.c is an offender
there)

<asm/segment.h> was replaced by <asm/uaccess.h> in 2.1.4 and we still have
references ...

Yes, agree totally,  i386 _requires_ asm/segment.h.  It is used in 
low-level trap handling and bootup code from assembly files.  In 
addition, even parts of userspace on i386 depend on asm/segment.h, 
although that is a different beast.

It is a total bug if generic drivers include it, there is simply no 
reason to use segment.h unless you have to use segmentation.  Ideally, 
all includes of segment.h should be confined to architectures that 
require it, and limited to either arch/foo or include/asm-foo.

I'm looking at -rc6-mm1, and I see the following bad guys:

./drivers/char/mxser.c:#include <asm/segment.h>
./drivers/char/speakup/speakup_drvcommon.c:#include <asm/segment.h>

but keeping the header under that name will just encorage people
to put it back into drivers, after all it compiles on i386..

Let's rename it even for i386.

That's a problem of glibc-kernheaders (or insert alternative $name here)
