I've become convinced that Something Really Bad happened to the KVM tree in
linux-next on its way to my laptop - after 2 bisects, it reported I had some
2,000 commits left to check.  So I ran 'git bisect visualize' to sanity check.

And *every single one* of those 4,000 commits between 'good' and 'bad' was a
KVM commit, stretching all the way back to 2007.  Unless that's an artifact
of the way linux-next is built, I would have expected only "new-ish" commits
to be in the bisect window, and not just out of one tree...

So I ended up doing a 'WTF?', an 'rm -r', and am cloning over today's linux-next
and will see if that brings me any better joy.
