Hi Chintan,

Hi Will,

Thanks for sticking with this. I've reviewed the series now and I'm keen
for it to land in mainline. Just a couple of things below.

Thanks for all the reviews so far.

This series of patches re-bring huge vmap back for arm64.

These patches can also go into '-stable' branch (if accepted)
for 4.6 onwards.

Not sure we need to target -stable, since we solved the crash by disabling
the use of huge io mappings.

If disabling of huge io mappings have gone into stable trees, then I
won't push for these changes there.

If you get an ack from the x86 folks, then I could take all of this via
arm64. Alternatively, now that I've reviewed the series this could happily
go via another tree (e.g. akpm).

Sure. I would wait for few days before either of them take notice of
this. If required, I will communicated with them.

Thanks,

Will
