Re: [PATCH] Retain old acpi policy for !CONFIG_CPU_IDLE

[Len Brown <lenb@kernel.org>]

I couldn't get this patch to apply.

the current cpuidle branch is rooted at 2.6.22.
I'd like to see a patch on top of that branch
that restores as much of processor_idle.c as possible
to the state in 2.6.22.

ie. a diff of 2.6.22 and cpuidle processor_idle.c
should be as small as possible -- and it is okay
to use a bunch of CONFIG_CPU_IDLE ifdefs to keep things simple.

I can take care of merging that with the other changes
to processor_idle.c that have come along in 2.6.23.

thanks,
-Len
