This is the 3rd version of my VGIC patches. Not much code change this time, apart from: - a handful of bugs fixed - some performance improvement - adapted to the new WFI handling code - reworked after Christoffer review - rebased on v11 One thing that hasn't changed yet is the interrupt injection API. Once we're happy with the rest of the code, it won't be a big deal to fix it, and there seem to be some thoughts in this area. We also need to investigate some of the most recent KVM injection features (KVM_IRQ_LINE_STATUS, irqfd...), but I don't see it as a blocker for a merge of this code. This is based on the kvm-arm-v11-stage branch, and is available at: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm-v3.6-rc3-vgic. It also relies on the fixes available on my kvm-arm-v3.6-rc3-fixes branch. Tested on the TC2 platform, A15 cluster only.
