[PATCH 0/9] Rework architected timer and fix UEFI reset

Hi Christoffer,

The architected timer integration with the vgic had some shortcomings in
that certain guests (one being UEFI) weren't fully supported.

In fixing this I also found that we are scheduling the hrtimer for the
virtual timer way too often, with a potential performance overhead.

This series tries to address these problems in proviging level-triggered
semantics for the arch timer and vgic intergration and seeks to clarify
the behavior when setting/clearing the active state on the physical
distributor.

Series based on kvmarm/next and also available at:
https://git.linaro.org/people/christoffer.dall/linux-kvm-arm.git timer-rework
I'm quite pleased with the overall look of this series. It fixes a
number of issues that have been around for a while, plus some others
I've recently introduced...

Now, I fear this is probably too big a series to be shipped as a fix for
4.3. Can you come up with a minimal series that we could merge quickly
(I'm thinking patches 7 and 9), and leave the rest for the following
merge window?

Thanks,

	M.
