Greg, can you pick that for 3.9.8?

<formletter>

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

That patch is already in Linus' tree and is marked correctly (AFAICS)
for 3.9 stable:

Yes, but the one can not be applied to v3.9 cleanly.
so at same time you have backporting for 3.9.

Greg applied that for 3.9.5 but it has compile error, as v3.9 acpiphp is still
able to be complied as module.

Per your request, I respin that patch
  https://patchwork.kernel.org/patch/2676821/
that will call request_module("acpiphp") at first.

Thanks

Oh, right, I forgot that.  Then I'll just let you take care of sending
that to Greg in the correct format.
