In mask/restore_ioapic_entries() we should be restoring ioapic
entries when ioapics[apic].saved_registers is not NULL.
Fix the typo and address the resume hang regression reported by
Linus.
This was not found sooner because the systems where these
changes were tested on kept the IO-APIC entries intact over
resume.

Commit d12337 (rwsem: Remove redundant asmregparm annotation)
broke rwsem on UML.
As we cannot compile UML with -mregparm=3 and keeping asmregparm only
for UML is inadequate the easiest solution is using RWSEM_GENERIC_SPINLOCK.
Thanks to Thomas Gleixner for the idea.

There is a lot of common code in the sys_m68k.c files. The mmu and non-mmu
versions can easily be merged into a single file.
There is really only 2 functions that differ in the 2 cases. A single
ifdef on CONFIG_MMU can take care of this. Alternatively we could break
those 2 functions out and maintain sys_m68k_no.c and sys_m68k_mm.c with
just this code in it (Makefile could then just build the right one).
Does anyone have strong feelings on which way they want this done?

After cleaning up m68k_ksyms_no.c it is now strait forward to merge
the non-mmu and mmu versions of m68k_ksyms.c. The need for the extra
gcc functions is not strictly based on having an MMU or not. It is
based on the family the processor belongs too, so use an appropriate
conditional check.

There is no reason most of the symbols enclosed in a conditional
on CONFIG_COLDFIRE need to be exported. And they sure don't need to

are currently needed) to the definitions of those, and remove the
rest of the exporting here.

Merging the mmu and non-mmu directories we ended up with duplicate
