Subject[PATCH 00/24] Use asm-generic for mmu_context no-op functions
Date
It would be nice to be able to modify these or add a hook without
updating all architectures, most of which just use noops.

There was some discussion around the lazy tlb switching vs membarrier
barriers that may have needed changes here to fix (addition of an
exit_lazy_tlb() function). I don't know whether that's what we will
end up doing, but these are the prep patches I did for it which are
still a good cleanup so I would like to mege them.

All arch patches depend on patch 1. If everybody is fine with it
then Arnd could merge that one in this merge window then we do the
rest of them in the next window?

Thanks,
Nick
