Merge tag 'kvm-arm-for-4.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-master
KVM/ARM changes for 4.3-rc2 - Fix timer interrupt injection after the rework that went in during the merge window - Reset the timer to zero on reboot - Make sure the TCR_EL2 RES1 bits are really set to 1 - Fix a PSCI affinity bug for non-existing vcpus
