[PATCH v2 0/5] GICv3: add 32bit compatibility

This series adds 32bit compatibility to Marc's GICv3 driver. Only SGIs,
PPIs and SPIs support is present, no ITS.

It is now based on Linux 4.0-rc1, which contains Andre's GICv3 emulation
series for KVM [1]. With this support along with the kvmtool patches
mentioned in [1], it is possible to run ARM guests that use GICv3.

Changes since v1 [2]:
* rebased on 4.0-rc1
* fix the mistakes pointed out by Russell and Vladimir
* add a patch to select ARM_GIC_V3 under ARCH_VIRT, as suggested by Marc
