[ACTIVITY] report week ending 4 Feb

Progress: * UM-2 [QEMU upstream maintainership] - Fixed some minor issues with the hvf accelerator and sent out a patchset + '-cpu max' didn't act like '-cpu host' + we weren't exposing PAuth to the guest * QEMU-420 [GICv4 emulation] - Sent out a patchset with more cleanups and fixes to the existing ITS code - The ITS parts of the GICv4 work are now code-complete; moving on to the redistributor end of things next week.
