Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which starts revamping the
migrate_vma functionality. The prime idea is to export three slightly
lower level functions and thus avoid the need for migrate_vma_ops
callbacks.

Changes since v2:
- don't unmap pages when returning 0 from nouveau_dmem_migrate_to_ram
- minor style fixes
- add a new patch to remove CONFIG_MIGRATE_VMA_HELPER
Changes since v1:
- fix a few whitespace issues
- drop the patch to remove MIGRATE_PFN_WRITE for now
- various spelling fixes
- clear cpages and npages in migrate_vma_setup
- fix the nouveau_dmem_fault_copy_one return value
- minor improvements to some nouveau internal calling conventions
Some of the patches seem to have been mangled in the mail.
I was able to edit them and apply to Jason's tree
https://github.com/jgunthorpe/linux.git mmu_notifier branch.
So for the series you can add:
