At some point I want to stage a merge tree QEMU bits here:

https://git.kernel.org/pub/scm/linux/kernel/git/devsec/qemu.git/ (not
created yet)

...unless Paolo or others in QEMU community are open to running a
staging branch in qemu.git. At some point we need to collide all the
QEMU POC branches, and I expect that needs to happen and show some
success before the upstream projects start ingesting all these changes.
