[ACTIVITY] report week ending 24 Jan

Progress: * VIRT-65 [QEMU upstream maintainership] - code review: + RTH's bug fix for the PAuth ComputePAC operation + patchset adding DMA support for Exynos4210 UARTs - small patchset documenting the right way to conditionally run expensive computations that are only needed for trace event output, and updating a handful of places that used an older (worse) method - more QEMU documentation conversion to rST; in particular wrote a Sphinx 'hxtool' extension to handle pulling out fragments of documentation from QEMU's '.hx' files which define and document command line options
