Hi Michael,
After merging the vhost tree, today's linux-next build (powerpc allyesconfig)
failed like this:

Caused by commit 89bfc4cdb438 ("cpuidle: kvm cpuidle").
Given that the commit message for this commit includes "Very much a
demo for now, downstream only." it should *not* be in linux-next. It
should especially not have turned up at this point (just before the
merge window). I also wonder about some of the other commits in that
tree :-(
I have reverted that commit for today.
