2009-01-29	sh: Fix up T-bit error handling in SH-4A mutex fastpath.	Takashi Yoshii	1	-12/+9
	This corrects a deadlock encountered on ap325 in the cases where the mutex is contended and the slow-path needs to be fallen back upon.

2008-12-22	sh: Fix up the SH-4A mutex fastpath semantics.	Paul Mundt	1	-16/+21
	This fixes up the __mutex_fastpath_xxx() routines to match the semantics noted in the comment. Previously these were looping rather than doing a single-pass, which is counter-intuitive, as the slow path takes care of the looping for us in the event of contention.
