Part1 is based on tip/master and Part2 is based on kvm/master.

With the current division, we should be able to compile and run part1
and part2 independently. This patch defines X86_FEATURE_SEV which is
currently been used by svm.c hence I kept the patch in Part2.

If we move it in Part1 then Part2 build will fail -- I am okay with
including it as a pre-cursor to Part2 series. Is this something acceptable?
