linux-toradex.git/arch/sh/include/asm/mutex-llsc.h, branch v3.2.29 Linux kernel for Apalis and Colibri modules sh: Fix up T-bit error handling in SH-4A mutex fastpath. 2009-01-29T02:56:03+00:00 Takashi Yoshii yoshii.takashi@renesas.com 2009-01-28T09:29:13+00:00 c20f326a62c046ee958c3aa584f183201adb229f 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.

sh: Fix up the SH-4A mutex fastpath semantics. 2008-12-22T09:43:52+00:00 Paul Mundt lethal@linux-sh.org 2008-12-08T02:25:50+00:00 77ba93a7ac5fb0d9338bffbf97c787b8efe00806 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.
