I was actually meaning to apply this (at least until patch 6; I'm
not convinced patch 7 makes sense to go in at this point), but
noticed that comments by Konrad were still un-addressed. I'm
also expecting some re-basing to be needed on top of Paul's
emulation re-work.

Wei, considering that this had already missed 4.5, would you
be okay to take at least first 6 patches (which seem reasonably
risk free) after the freeze?
