This is the second version of my in-kernel timers using the
architected timer. Not much has changed, apart from taking
Christoffer's consideration into account, and fixing a couple of
glaring bugs.
This relies on my previously posted VGIC series.
This is based on the kvm-arm-v10-stage branch, and is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git
kvm-a15-v10-stage-v3.5-rc5-vgic
Tested on the TC2 platform, A15 cluster only.
