I think all these are ready to go having been mostly reviewed in previous
series. The following still need review:

  util/timer: avoid deadlock when shutting down
  tests/tcg: add a system test to check memory instrumentation
  tests/tcg: ensure s390x-softmmu output redirected
  tests/tcg/multiarch: add test for plugin memory access (0 acks, 1 sobs, 1 tbs)
