Applied patch 2 to kvm-x86 fixes and tagged it for stable, and applied patch 1
to misc. Not zeroing eax/ebx is relatively benign, as it only affects the
!enable_pmu case, but it's most definitely a bug and the fix is about as safe
as a fix can be.
I also added quite a bit of extra information to both changelogs.
Thanks!
