[PATCH v4 0/3] drm/nouveau: set DMA mask before mapping scratch page
This v4 is now a 3 piece series, after Alexandre pointed out that both
GF 100 and NV50 are affected by the same issue, and that a related issue
has been solved already for Tegra in commit 9d0394c6bed5
("drm/nouveau/instmem/gk20a: set DMA mask early").
The issue that this series addresses is the fact that the Nouveau driver
invokes the DMA API before setting the DMA mask. In both cases

turn hmm migrate_vma upside down v2
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.
