Subjectturn hmm migrate_vma upside down v2
Date
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.

Diffstat:

5 files changed, 281 insertions(+), 607 deletions(-)

A git tree is also available at:

git://git.infradead.org/users/hch/misc.git migrate_vma-cleanup.2

Gitweb:

http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/migrate_vma-cleanup.2

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
