Date: Mon, 2 Feb 2009 23:05:10 +0100 From: Uwe Kleine-König <u.kleine-koenig@...gutronix.de> To: linux-kernel@...r.kernel.org Cc: Steven Rostedt <rostedt@...dmis.org> Subject: [PATCH] [ARM] use __preempt_enable_no_resched in cpu_idle() instead of preempt_enable_no_resched. The only difference is that the latter wails if preempt_count drops to zero. This however is OK here as schedule is called afterwards. The same was done for x86 in 932e227146fbb26ea4688c126d0fd3953787f6a4. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@...gutronix.de> --- Hello, this patch can be found in my repo at git://git.pengutronix.de/git/ukl/linux-2.6.git rt/rt-locks as 7750516b5d0 basing on Steven's rt/rt-locks branch.
