[patch 07/19] mutex subsystem, add default include/asm-*/mutex.h files

[Ingo Molnar]

From: Arjan van de Ven <arjan@xxxxxxxxxxxxx>

add the per-arch mutex.h files for the remaining architectures.

We default to asm-generic/mutex-dec.h, because that performs
quite well on most arches. Arches that do not have atomic
decrement/increment instructions should switch to mutex-xchg.h
instead. Arches can also provide their own implementation for
the mutex fastpath primitives.
