Progress:
* VIRT-65 [QEMU upstream maintainership]
+ Just the usual code review and pull request work.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ I have all fp16 insns (both VFP and Neon) implemented now, and the
VFP patches have been reviewed. Just need to track down a few last
test failures and then I can send the Neon patches out for review.
thanks

Progress (short week, 2 days):
* VIRT-65 [QEMU upstream maintainership]
+ We got 5.1 out the door. I think this is the first release
in the many years I've been handling them where we managed to
avoid needing an rc4.
+ Spent a fair amount of time helping Paolo to debug his conversion
of the QEMU build system to Meson. We managed to land that today.
+ First of the KVM Forum programme committee meetings
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ More progress with fp16 support work; another handful of insns done.
thanks

I got an email and an irc ping for
http://lab.llvm.org:8011/builders/lldb-aarch64-ubuntu/builds/6924
My change has no relation to the test failure.
Flaky bots aren't allowed to send email or ping, so either make it
non-flaky or make it not send stuff.
Thanks,
Nico
[VIRT-327 # Richard's upstream QEMU work ]
Patch review -- lots of riscv vector stuff.
Fix for PAUTH error indication.
Diagnosed an MTE KASAN problem
-- my theory is a guest os thread error.
Investigation into PAUTH slowdown.

Realised I missed last week so bumper update.
