With this one, things have changed quite a bit. I'll take a deeper look
at what you did and figure out how this applies to v3.0-rt.

It doesn't look like this patch is needed for v3.0-rt as the patch
addresses the new stop_machine_from_inactive_cpu() API used by the mtrr
code added by this commit:

    x86, mtrr: use stop_machine APIs for doing MTRR rendezvous


This was added in 3.1 so the patch is still required for v3.2-rt.
