Do you really believe that open-coding x86_capability[9] in .../common.c
is better than the open-coding in ../powernow-k8.c ?

Again, open-coding is wrong and error prone. Ingo explicitely asked for a
helper function. All you did is moving the open-coded hard wired array
reference to a different place.

Please start to listen to the review comments as long as people are
willing to look at your patches. Seriously, the noise/useful ratio of
your patches is annoying and adds an unjustified burden to the
maintainers of that code.

Thanks,

tglx
