[RFC 0/2] irqchip/gic-v3-its: Introduce virtual ITS

[Boqun Feng]

Hi Marc,

Here is an RFC for supporting platforms having LPI supported but without
ITS. And this is for the virtual PCI support for ARM64 Hyper-V guests.
We currently choose this approach (LPI w/o ITS) because a) it's allowed
for GICv3 and b) ITS may not be a more efficient way to configure LPIs
compared to hypercalls, but we'd like to get feedbacks from the
community.

Besides, patch #1 fixes a bug which I found while I was at it.

Looking forwards to any comment and suggestion!

Regards,
Boqun
