[ACTIVITY] report week ending 1 Oct

Progress * UM-2 [QEMU upstream maintainership] + Worked through my code-review backlog + Noticed that we never got round to making our emulated GICv3 support having redistributors in more than one contiguous region; this prevents using more than 123 CPUs with the virt board. Sent out a patchset which adds the necessary handling. + Generally trying to tie off loose ends pre-holiday :-)
