Hi Stephen,

Sorry for the delay.

I fished the patch of LKML and have applied it from today.  However, I
think SH may need a further patch for this errors:

arch/sh/kernel/idle.c:25: error: static declaration of 'pm_idle' follows non-static declaration
include/linux/pm.h:34: error: previous declaration of 'pm_idle' was here

Len, can you please get these fixed up in your idle-test tree.
