Thanks for the detailed reviews. Hopefully this is the last one...

Since v3:
- Addressed Thomas's review comments:
- Patch 2 initrd cleanup unset the old variable in the correct place.
- Patch 4 multi migration removed the extra wait for "Now migrate the
VM" message, and updated comments around it.
- Patch 6 fix typo and whitespace in quiet migration support.
- Patch 8 fix typo and whitespace in migration selftest.

Since v2:
- Rebase on riscv port and auxvinfo fix was merged.
- Clean up initrd cleanup moves more commands into the new cleanup
function from the trap handler comands (suggested by Thomas).
- "arch-run: Clean up temporary files properly" patch is now renamed
to "arch-run: Fix TRAP handler..."
- Fix TRAP handler patch has redone changelog to be more precise about
the problem and including recipe to recreate it.
- Fix TRAP handler patch reworked slightly to remove the theoretical
race rather than just adding a comment about it.
- Patch 3 was missing a couple of fixes that leaked into patch 4,
those are moved into patch 3.

Thanks,
Nick
