    Date
    From
    Subject[patch 06/13] 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.
