Functions implemented in cpufeature.h depend on some headers, but
cpufeature.h does not include them. This may cause build failure if
cpufeature.h user does not include that headers by itself. (Like it
happens in next patch of this series.)

We're also missing <linux/compiler.h> for the __attribute_const__ on
cpuid_feature_extract_field.

The cpu_feature macro using ilog2 is prior to the __ASSEMBLY__ guard.
Given it cannot be used by assembly, I think it should also be pulled
under the guard, or removed as it doesn't appear to be used anyway
(which would remove the need for this include).

Otherwise this looks good to me.

Thanks,
Mark.
