586b610e43 locking, asm-generic: Rework atomic-long.h to avoid bulk code duplication 
We can use some (admittedly ugly) macros to generate the 32-bit and
64-bit based atomic_long implementations from the same code.

5b02ee3d21 asm-generic: merge branch 'master' of torvalds/linux-2.6 
Fixes a merge conflict against the x86 tree caused by a fix to
atomic.h which I renamed to atomic_long.h.

72099ed271 asm-generic: rename atomic.h to atomic-long.h 
The existing asm-generic/atomic.h only defines the
atomic_long type. This renames it to atomic-long.h
so we have a place to add a truly generic atomic.h
that can be used on all non-SMP systems.
