[ACTIVITY] report week 8

Progress: * updated various Virtualization category cards in cards.linaro.org with my comments and clarifications * rebased qemu-linaro on upstream 1.4.0 * upstream code review: pl330 and others * prompted by LP:1129571 into another look at the linux-user threading issues. I dusted off an ancient patch I'd written to address one part of these, rebased it and rewrote it to work properly. * KVM/ARM kernel patches are now upstream, so we can submit the QEMU patches; started on a final rebase, polish and test

Absences: * NB: I now work a 4 day week, excluding Wednesdays * 4-8 March: Linaro Connect Asia (Hong Kong)
