Great!

Note that the dependencies are even more relaxed that that: you can 
push it too via the KVM tree, independently of the x86 push. Obviously 
you got those x86 changes from us x86 maintainers and they all work 
standalone too.

Pulling from each other means both sides agree on that sub-set of 
changes and trust each other - so there's no forced merge ordering or 
maintenance boundaries - any side can merge it upstream. (If you feel 
uneasy about it on any level, and were you to send a pull request 
first, then you can point it out to Linus in the pull request that you 
got those changes from us.)
