Adjust the asm symlink support so we do not create the
symlink unless really needed.
We check the precense of include/asm-$ARCH by checking
for the system.h file. We may end up with a stale directory
so it is not enough to check if the directory is present.

Since 97965478 ("mm: Get rid of __ZONE_COUNT")
mmzone.h includes bounds.h.
Calling make clean after make prepare removes bounds.h
again so when building external modules this fails.

Add the ability to pass comments into asm-offsets.h by generating asm
output like

-># comment line

Mips needs this feature to preserve the comments that are in
asm-mips/asm-offsets.h right now.

Then remove the special handling for mips from Kbuild and convert mips to use
the new string to include the comments.

The use of enums create constants that are not available to the preprocessor
when building the kernel (f.e.  MAX_NR_ZONES).

Arch code already has a way to export constants calculated to the preprocessor
through the asm-offsets.c file.  Generate something similar for the core
kernel through kbuild.

Preparatory patch for the source merge of arch/i386 and arch/x86_64
into arch/x86. This allows to keep the original arch directories as
stubs for the main Makefiles, Kconfigs et. al during the transition
phase while having the code in the new arch/x86 directory.

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.

No file in rpm binary package should have the RPM_BUILD_ROOT string in it.
To simplify building of external modules, our kernel-source package
contains some temp files from the Kbuild system.  asm/asm-offsets.h is one
of the files that contains the absolute path if make O=$O is used.

  * This file was generated by /var/tmp/kernel-source-2.6.14_rc4-build/usr/src/linux-2.6.14-rc4-2/Kbuild

Remove the $RPM_BUILD_ROOT string in the shipped tempfile.

Changes to Makefile.kbuild ("kbuild: add -fverbose-asm to i386
Makefile") breaks asm-offset.h file on MIPS.  Other archs possibly
suffer this change too but I'm not sure.

Here is a fix just for MIPS.

Removed obsolete stuff from arch makefile.
mips had a special rule for generating asm-offsets.h so preserved it
using an architecture specific hook in top-level Kbuild file.
Renamed .h file to asm-offsets.h
Signed-off-by: NSam Ravnborg <sam@ravnborg.org>

Building asm-offsets.h has been moved to a seperate Kbuild file
located in the top-level directory. This allow us to share the
functionality across the architectures.

The old rules in architecture specific Makefiles will die
in subsequent patches.

Furhtermore the usual kbuild dependency tracking is now used
when deciding to rebuild asm-offsets.s. So we no longer risk
to fail a rebuild caused by asm-offsets.c dependencies being touched.

With this common rule-set we now force the same name across
all architectures. Following patches will fix the rest.
