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 23:11:57
+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
