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.
