Cover letter [PATCH 0/12]: MUTEX: Introduce mutex implementation

This set of patches implements mutexes as an alternative to semaphores where such more restricted behaviour is appropriate.

There are several changes that might be appropriate to these patches:

(1) Name DECLARE_MUTEX as DEFINE_MUTEX in linux/mutex-*.h

(2) Make mutex_trylock()'s return value consistent with semaphores rather than everything else.

(3) Drop the testing module (patch 12/12). I'm not sure I've got the plumbing correct in the master makefile.

Patches to come after Christmas will include sem -> completion conversions and sem -> mutex conversions.

Merry Christmas!

David
