mm/hmm: fix utf8 ...

Browse Source 
Patch series "HMM updates, improvements and fixes", v2

Few fixes that only affect HMM users.  Improve the synchronization call
back so that we match was other mmu_notifier listener do and add proper
support to the new blockable flags in the process.

For curious folks here are branches to leverage HMM in various existing
device drivers:

https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-nouveau-v01
https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-radeon-v00
https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-intel-v00

More to come (amd gpu, Mellanox, ...)

I expect more of the preparatory work for nouveau will be merge in 4.20
(like we have been doing since 4.16) and i will wait until this patchset
is upstream before pushing the patches that actualy make use of HMM (to
avoid complex tree inter-dependency).

This patch (of 6):

Somehow utf=8 must have been broken.
