Hi,

This is a quick update to the series I posted at the end of last week.
It mostly adds a bunch of review tags. There are two changes of note:

  cputlb and arm/sparc targets: convert mmuidx flushes...

  This has been updated to reduce the churn of the previous iteration
  by doing all the MMUIdx shifting in-situ for the tlb_flush calls.

And:

  tcg: enable MTTCG by default for ARM on x86 hosts

  Mostly cosmetic tweaks but I have clarified the semantics of the
  TCG_MO_foo declarations with a tweak to the TCG_TARGET_DEFAULT_MO on
  x86 to be (TCG_MO_ALL & ~TCG_MO_ST_LD).

From v8 rth said:

  "As far as I'm concerned, I'm done with my review and this can go in."

So this is really your last chance to raise any concerns or questions
before the merge (although of course bug fixes can go in later ;-).

Peter,

The patches that touch ARM and that could do with maintainer sign-off are:

  tcg: enable MTTCG by default for ARM on x86 hosts
  target-arm: ensure all cross vCPUs TLB flushes complete
  target-arm: introduce ARM_CP_EXIT_PC
  target-arm/cpu.h: make ARM_CP defined consistent
  target-arm: don't generate WFE/YIELD calls for MTTCG
  target-arm/powerctl: defer cpu reset work to CPU context
  cputlb and arm/sparc targets: convert mmuidx flushes from varg to bitmap
  tcg: drop global lock during TCG code execution

Cheers,
