The traditional location of the arch specific Makefiles
has been at:

But as suggested by several people over time and lately
by Linus in the following post:
http://kerneltrap.org/mailarchive/linux-kernel/2008/5/21/1903924
is is suggested to move the arch specific files under arch/
and for the header files this is arch/$ARCH/include.
So I have hacked up support for this in kbuild so
for the simpler cases a simple move of header files as
in:
git mv include/asm-$ARCH arch/$ARCH/include/asm
is enough.
If Linus will accept it then I think -rc1 is a perfect
time to do it as people has less stuff pending touching
the header files that are moved.
Validation is easy - does the usual configs build?
For the archs that plays games with symlinks this is a
splendid opportunity to get rid af these.
The receipe is simple:
Use
KBUILD_CFLAGS += -Iarch/$ARCH/include/$CPU
to select the CPU and then do a copy of the header files
like this:
git mv include/asm-$ARCH/$CPU arch/$ARCH/include/$CPU/cpu
Then the code can continue to use:
#include <cpu/foo.h>
I already converted sparc to use arch/sparc/include -
while I merged the header files for sparc and sparc64.
This change is already upstream.
And for SH I posted a receipe which you can read here:
http://lkml.org/lkml/2008/7/28/83
It is SH specific but anyway pretty generic.
I am limited in time and resources at the moment but I
would be glad to help out as time permits should there
be any questions.
I just tried moving the include/asm-m68knommu directory
to arch/m68knommu/include/asm and it all worked fine.
Clean compile first go :-) Nice. (As noted
asm-offsets.h was still generated in incldue/asm-m68knommu
afterwards though).
So what is the status, should I prepare git/patch
for Linus?
Yes please do so.
The move change can be pulled from:
git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu.git for-linus
If there is no complaints I'll send Linus a pull request in a
couple of days time.
Regards
Greg
