I think so. I haven't tried your patch yet (I managed to miss it ;-)), but
reversing the "+reduce-tlb-flushing-during-process-migration-2.patch"
helps here, so I assume the answer is "yes".

This is related to the previous one, certainly. I'm unable to reproduce it
after reversing the "+reduce-tlb-flushing-during-process-migration-2.patch",
too.
The trace would probably look very much like that one:
