[ACTIVITY] report week ending 21 Apr

Progress: * UM-2 [QEMU upstream maintainership] - sent out v3 of the 'deprecate singlestep option' patchset - sorted out the draft QEMU Summit invite list and invitation text - spent some time trying to understand how the imx SoCs arrange their ethernet controllers and PHYs so I can review a patchset - sent patch fixing minor configure nit where it wasn't honouring --cross-prefix for the ObjC compiler - got the 8.0 release out of the door and handed over merge handling to rth - sent some patchsets updating a few old .txt files to reStructuredText - still thinking about our page-table-walk code -- I'm not convinced it's doing the right thing with NSW/SW bits, even after last week's patchset...
