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
