Subject: turn hmm migrate_vma upside down v3
Date: Wed, 14 Aug 2019 09:59:18 +0200
Message-ID: <20190814075928.23766-1-hch@lst.de> (raw)

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
