Subject: [RESEND PATCH v1 0/6] Support GICv3 ITS in 32-bit mode

Hi,

This series introduces GICv3 ITS to 32-bit world. Since I'm limited
with real world 32-bit platforms which uses ITS it was tested with
help of vITS on 64-bit host running 32-bit guest.

I used Andrea's its/v8 branch at [1] with following option passed to
kvmtool: --aarch32 --irqchip=gicv3-its --force-pci

[1] git://www.linux-arm.org/kvmtool.git

Changelog:

    RFC -> v1
        - rebased on 4.9-rc2,  gits_read_typer() has been dropped
	- spilt ITS and vITS in separate patch sets
	
Vladimir Murzin (6):
  irqchip/gic-v3-its: Change unsigned types for AArch32 compatibility
  irqchip/gic-v3-its: Narrow down Entry Size when used as a divider
  irqchip/gicv3-its: Specialise flush_dcache operation
  irqchip/gicv3-its: Specialise readq and writeq accesses
  ARM: gic-v3-its: Add 32bit support to GICv3 ITS
  ARM: virt: Select ARM_GIC_V3_ITS
