4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Borislav Petkov <bp@xxxxxxx>

commit cd4d09ec6f6c12a2cc3db5b7d8876a325a53545b upstream

Move them to a separate header and have the following
dependency:

x86/cpufeatures.h <- x86/processor.h <- x86/cpufeature.h

This makes it easier to use the header in asm code and not
include the whole cpufeature.h and add guards for asm.
