[ACTIVITY] report week ending 18 June

Progress: (very short week, 2 days) * VIRT-65 [QEMU upstream maintainership] + found and sent patches for a handful of minor M-profile bugs * VIRT-268 [QEMU support for dual-core Cortex-M Musca board] + the final patches for this have now gone upstream and I have marked the JIRA issue as resolved. There may still be minor bug fixes but we can handle those under the usual 'upstream maintainership' JIRA

thanks -- PMM
