[ACTIVITY] report week ending 7 Dec

Progress: * VIRT-65 [QEMU upstream maintainership] - release work (we needed an rc4, and then an rc5 due to a late-breaking security bug) - wrote a patch which I hope will fix synchronization of system register state to KVM for a case where QEMU code wants to change the register values, which it does when QEMU is arranging to inject an exception into the guest - catching up on patch review and assembling target-arm.next ready for when the tree reopens - some simple patches fixing minor memory leaks spotted by clang LeakSanitizer - sent a patch for a race condition that meant we would sometimes ignore a guest-requested system reset or otherwise get confused by it

thanks -- PMM
