From 9bed07d0fed01f7c39d128e59e5d35d7d67ff439 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Sat, 3 Sep 2005 19:39:26 +0100 Subject: [PATCH] [ARM] 2874/1: S3C2410 - add cpu_init() call after sleep wakeup Patch from Ben Dooks The power management sleep code needs to call cpu_init() to restore the cpu state after the system resumes from suspend. Also clear off an un-necessary comment. Thanks to Dimitry Andric for reporting the bug and for rmk for pointing out the cause.
