This was included in v3.18-rc3.

Andi spotted this typo (see https://lkml.org/lkml/2014/10/28/455 ). So
did my local perl script when it hit next-20141029. But since this was
already discussed I didn't bother to mention it too.

One expects this to be fixed by s/SUP_SUP_INTEL/CPU_SUP_INTEL/. Perhaps
the fix is more complicated, but anyhow, the typo isn't fixed in
next-20141103 or, as far as I can tell, in tip.git. So I decided to
remind you to make sure this doesn't fall through the cracks.
