So updated HMM patchset :
https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-v20

I am not posting yet as it seems there is couple thing you need to
fix in your patchset first. However if you could review :

https://cgit.freedesktop.org/~glisse/linux/commit/?h=hmm-v20&id=84fc68534e781cf6125d02b3bfdba4a51e82d9c9

As it was your idea, i just want to make sure i didn't denatured
it :)

Also as side note, v20 fix build issue by restricting HMM to x86-64
which is safer than pretending this can be use on any random arch
as build failures i am getting clearly shows that thing i assumed to
be true on all arch aren't.

Cheers,
J?r?me
