Merge tag 'kvm-arm-for-v4.12-rc5-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/ARM Fixes for v4.12-rc5 - Take 2 Changes include: - Fix an issue with migrating GICv2 VMs on GICv3 systems. - Squashed a bug for gicv3 when figuring out preemption levels. - Fix a potential null pointer derefence in KVM happening under memory pressure. - Maintain RES1 bits in the SCTLR_EL2 to make sure KVM works on new architecture revisions. - Allow unaligned accesses at EL2/HYP
