[ACTIVITY] report week ending 22 Jan

[Peter Maydell]

Progress:
 * UM-2 [QEMU upstream maintainership]
+ Code review (including RTH's MTE-for-user-mode-emulation)
+ Investigating an intermittent failure of a test case involving
  an s390 guest on aarch64 hosts...
 * QEMU-364 [QEMU support for ARMv8.1-M extensions]
+ Converted the ARMSSE (IoTKit/SSE-200) code over to use the Clock
  framework, which was added to QEMU after ARMSSE was first written.
  (This is a prereq for adding the new-in-SSE-300 timer device, which
  will use Clocks.) Sent the patches out for review.

I'm currently experimenting with a schedule of:
 Mon: JIRA task work; Tue: code review; Thu: JIRA task work; Fri: misc upstream

thanks
