[ACTIVITY] report week ending 1 Dec

Progress: * UM-2 [QEMU upstream maintainership] - Sent a pullrequest for this week's rc - Sent a patch which disables SME if SVE is disabled, since QEMU currently asserts if you try to use that combination.

* QEMU-623 [Nested Virtualization Emulation] - Mostly working through debugging issues in my FEAT_NV/FEAT_NV2 emulation. I can get the inner guest kernel to boot up to the point where it tries to 'eret' and the outer kernel thinks that's an invalid exception return. More debugging scheduled for next week...
