Subject: [PATCH 0/3] irqchip/gic-v3: Assorted fixes and improvements

This is a small series that happens on the back of [1], which
implements additional features in KVM's vgic.

The first patch fixes a pretty embarrassing bug, which is fortunately
unlikely to cause any issue in real life. The next two patches are
performance optimisations.

Thanks,

        M.
