In order to get people to test this a bit more, I've now pushed this
series into -next. I'm pretty confident that it won't break a thing, but
better safe than sorry. I also expect any fix to be pushed on top of
this series.

This doesn't mean that the review is over, quite the opposite. I intend
to go over it once more, and I'd like other people to do the same
(specially anyone looking at implementing the required support in QEMU).

Thanks,

M.
