[ACTIVITY] report week ending 6 Nov

Progress: * VIRT-65 [QEMU upstream maintainership] + usual release cycle work + Our Coverity-Scan issues had been left untended a bit too long: went through them doing triage, reporting them back to patch submitters, and writing a few fixes for some of the easy ones + That took me down a rabbit-hole of fixing some issues with our sparc64 usermode emulation so I could demonstrate that the coverity fixes hadn't broken anything...

thanks -- PMM
