[PULL v2 0/6] KVM/ARM Fixes for v4.12-rc5 - Take 2

[Christoffer Dall]

Hi Radim and Paolo,

Six additional fixes for KVM/ARM for v4.12 (instead of only the first
three in the first version of this pull request).

The changes are:
 - 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

The following changes since commit fa472fa91a5a0b241f5ddae927d2e235d07545df:

  KVM: arm/arm64: Hold slots_lock when unregistering kvm io bus devices (2017-05-18 11:18:16 +0200)
