Update code that relied on sched.h including various MM types for them.
This will allow us to remove the <linux/mm_types.h> include from <linux/sched.h>.

We are going to split <linux/sched/debug.h> out of <linux/sched.h>, which
will have to be picked up from other headers and a couple of .c files.
Create a trivial placeholder <linux/sched/debug.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.
Include the new header in the files that are going to need it.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/'
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

As execution domain support is gone we can remove
signal translation from the signal code and remove
exec_domain from thread_info.

Fix up all callers as they were before, with make one change: an

For the explicit calls to .udiv/.umul in assembler, I made a
mechanical (read as: safe) transformation. I didn't attempt
to make any simplifications.
In particular, __ndelay and __udelay can be simplified significantly.
Some of the %y reads are unnecessary and these routines have no need
any longer for allocating a register window, they can be leaf
functions.

These files are only exporting symbols, so they don't need
the full module.h header file. Previously they were getting
access to EXPORT_SYMBOL implicitly via overuse of module.h
from within other .h files, but that is being cleaned up.

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

Move all applicable EXPORT_SYMBOL()s to the file where the respective
symbol is defined.
Removed all the includes that are no longer needed in sparc_ksyms_32.c
Comment all remaining EXPORT_SYMBOL()s in sparc_ksyms_32.c
Two symbols are shared with sparc64 thus the exports were removed from
the sparc_ksyms_64.c too, along with the include their ommission made
redundant.

Additions by Julian Calaby:
* Moved EXPORT_SYMBOL()s for prom functions to their rightful places.
* Made some minor cleanups to the includes and comments of sparc_ksyms_32.c
* Made another subtraction from sparc_ksyms_64.c
* Updated and tidied commit message.
* Rebased patch over sparc-2.6.git HEAD.
* Ensured that all modified files have the correct includes.

Renaming a few types to contain a 32 suffix makes the
type names compatible with sparc64 and thus makes sharing
between the two a lot easier.
Note: None of these definitions are expected part of the
stable ABI towards userspace.

o sparc32 files with identical names to sparc64 renamed to <name>_32.S
o introduced a few Kconfig helpers to simplify Makefile logic
o refactored Makefile to prepare for unification
- use obj-$(CONFIG_SPARC32) for sparc32 specific files
- use <name>_$(BITS) for files where sparc64 has a _64 variant
- sparc64 directly include a few files where sparc32 builds them,
refer to these files directly (no BITS)
- sneaked in -Werror as used by sparc64
o modified sparc/Makefile to use the new names for head/init_task
