[PATCH 00/11] irqchip/gic-v3-its: Cleanup and fixes for Linux 5.5

Hi all,

This series is a mix of early GICv4.1 cleanups, fixes coming out of
discussions with Zenghui Yu, and a couple of stashed bug fixes that I
recently rediscovered (oops).

Hopefully nothing controvertial here, but please shout if you think
anything looks wrong. I've given it a good shake on my D05, and
everything was great (until the SSD containing the home directories
decided it had enough with life and everything ground to a halt).

As $SUBJECT says, I plan to take this into 5.5.

Thanks,

M.
