Hi Jérôme, Ben, Felix and Jason,

below is a series against the hmm tree which cleans up various minor bits and allows HMM_MIRROR to be built on all architectures.

Diffstat:

11 files changed, 94 insertions(+), 210 deletions(-)

A git tree is also available at:

Gitweb:

Changes since v1:

• fix the cover letter subject
• improve various patch descriptions
• use svmm->mm in nouveau_range_fault
• inverse the hmask field when using it
• select HMM_MIRROR instead of making it a user visible option

I think it is straightforward enough to move into -next, so applied to the hmm.git lets get some more reviewed-bys/tested-by though.

For now I dropped 'remove the pgmap field from struct hmm_vma_walk' just to hear the followup and 'amdgpu: remove CONFIG_DRM_AMDGPU_USERPTR' until the AMD team Acks

Thanks, Jason
