This is looking pretty good to me now and I feel that the longer it stays
out-of-tree, the more issues will creep in (without continual effort from
yourself and others). I've sent some minor comments (mainly vgic-related)
so, if you fix those, then you can add:

Reviewed-by: Will Deacon <will.deacon@arm.com>

for the series.

Now, there's a lot of code here and merging isn't completely
straightforward. I propose:

* The first series should go via Russell's tree. It depends on my
perf branch for the CPU type stuff, but that should go in for 3.9
anyway (also via Russell).

* The vGIC patches need rebasing on top of Rob Herring's work, which
he sent a pull for over the weekend:

http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/141488.html

In light of that, this stuff will need to go via arm-soc.

* The hyp arch-timers are in a similar situation to the vGIC: Mark Rutland
is moving those into drivers:

http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/140560.html

so the kvm bits will need rebasing appropriately and also sent to
arm-soc (Mark -- I assume you intend to send a PULL for 3.9 for those
patches?)

Obviously this is all open for discussion, but that seems like the easiest
option to me.

Cheers,

Will
