Hi Paolo,
Here is a bunch of fixes for the next -rc, focusing on the PSCI
implementation (spec conformance), and the usual vGIC patches
(preventing userspace from messing with the HW state and plugging a
couple of memory leaks).
Please pull,
M.

Merge branch 'kvm-arm64/vgic-fixes-5.7' into kvmarm-master/master (2020-04-23 16:27:33 +0100)
----------------------------------------------------------------
KVM/arm fixes for Linux 5.7, take #1
- Prevent the userspace API from interacting directly with the HW
stage of the virtual GIC
- Fix a couple of vGIC memory leaks
- Tighten the rules around the use of the 32bit PSCI functions
for 64bit guest, as well as the opposite situation (matches the
specification)
