[ACTIVITY] report week ending 27 Sep

Progress: * VIRT-65 [QEMU upstream maintainership] + identified cause of LP:1844597 and sent patch fixing it (we broke direct-booting kernels when the emulated system has an AArch32 EL3) + tracked down the cause of LP:1777777 to a race condition that's inherent to the current design of QEMU's 'ptimer' countdown timers; fixing this will require us to rethink when we call the callback when a ptimer hits 0. Posted some ideas to mailing list, for feedback on whether I missed a better way to rework them. + usual upstream maintainer stuff; managed one way or another to get a few of the most obstinately sticky patchsets off my to-review list

thanks -- PMM
