mutex subsystem, add default include/asm-*/mutex.h files
PATCH 6/11 mutex subsystem, add default include/asm-*/mutex.h files
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.
