Applied to kvm-x86 next.  In the future, please only bundle related and/or
dependent patches, especially for one-off patches.  It's a lot easier on my
end (and likely for most maintainers and reviewers) to deal separate series.

E.g. if you need to spin a new version, then you aren't spamming everyone
with 10+ patches just to rev one patch that might not even be realted to the
rest.  And having separate series makes it easier to select exactly what I
want to apply.

Concretely, at a glance, this could/should be 7 different patches/series:

   1, 2, 3-5 + 7 + 10-11, 6, 8, 9, 12-13, 14
