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

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
