[PATCH 0/2] GICv4.1 fixes for 5.7

From: Marc Zyngier

Here's a couple of GICv4.1 fixes for issues that have been found
during the 5.7 merge window.

The first one implements the "Dirty+Valid" feature, where the
hypervisor can wait for the GIC to have finish parsing the VPT before
entering the guest. The feature was optional in GICv4.0, but is now
mandatory in GICv4.1, so let's take advantage of it.

The second patch fixes an issue where the kernel shouts about the
effective affinity of VSGIs not being updated, which is the absolute
truth. Let's fix it.

I plan to send these fixes as part of a bigger pull request for -rc2.

Thanks,

M.
