Hi Thomas, Jason,
Here's the pull request for the GIC updates I stashed over the past few weeks. Only real new feature is the 32bit support from Jean-Philippe, the rest is all about dealing with errata and firmware.
Please pull!
Thanks,
M.

arm/arm64: KVM: Only allow 64bit hosts to build VGICv3 (2015-10-09 15:35:11 +0100)
---------------------------------------------------------------- GIC updates for Linux 4.4:
- Enable basic GICv3 support on 32bit ARM (mostly for running VMs with more than 8 virtual CPUs) - arm64 changes to deal with firmware limitations that forces a GICv3 to be used as a GICv2 - A GICv2m erratum workaround on Applied Micro X-Gene2
---------------------------------------------------------------- Duc Dang (1): irqchip/gic-v2m: Add workaround for APM X-Gene GICv2m erratum
Jean-Philippe Brucker (6): irqchip/gic-v3: Refactor the arm64 specific parts irqchip/gic-v3: Change unsigned types for AArch32 compatibility irqchip/gic-v3: Specialize readq and writeq accesses ARM: add 32bit support to GICv3 ARM: virt: select ARM_GIC_V3 arm/arm64: KVM: Only allow 64bit hosts to build VGICv3
Marc Zyngier (5): arm64: el2_setup: Make sure ICC_SRE_EL2.SRE sticks before using GICv3 sysregs irqchip/gic-v3: Make gic_enable_sre an inline function arm64: cpufeatures: Check ICC_EL1_SRE.SRE before enabling ARM64_HAS_SYSREG_GIC_CPUIF irqchip/gic: Warn if GICv3 system registers are enabled arm64: Update booting requirements for GICv3 in GICv2 mode
