[ACTIVITY] report week ending 16 Apr

Progress: (very short week, 2 days) * VIRT-65 [QEMU upstream maintainership] + QEMU release work: flurry of last minute stuff for rc3. I hoped we would not need an rc4, but as usual a release-critical issue was found, so we will be having one. + code review * VIRT-268 [QEMU support for dual-core Cortex-M Musca board] + worked through some final bug fixes + sent out v1 of the FP support patchset for review

thanks -- PMM
