FTR, even though 8f34f1eac382 applies cleanly it does not compile.
The 1st patch of that series is also required (5fc7a5f6fd04) - it removes
use of
*vma, which is later removed by the patch that fixes the actual problem.

Please feel free to give it a shot with the two backport series to see
whether
you spot any issue with it so far.

It seems like a normal cherry-pick without any extra changes around (please
correct me if I'm wrong),
so I've already added that to our internal kernel builds and so far I did
not spot any issues
(but as the issue does not happen frequently, I can't confirm if it is
really fixed but I trust Hugh
that he identified that as the commit that should fix it).

Anyhow, I'll keep looking around and let you know if I spot anything :)

Sorry for the trouble.

Thanks for providing fixes!
