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:

but I had only been able to get this:

before the machine hanged solid after rmmod (the serial console doesn't work, as I've already reported).
