[PATCH 00/16] mm/hmm/nouveau: THP mapping and migration

[Ralph Campbell <rcampbell@nvidia.com>]

These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go
into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM
self tests. Patch 7-8 prepare nouveau for the meat of this series which
adds support and testing for compound page mapping of system memory
(patches 9-11) and compound page migration to device private memory
(patches 12-16). Since these changes are split across mm core, nouveau,
and testing, I'm guessing Jason Gunthorpe's HMM tree would be appropriate.

Ralph Campbell (16):
  mm: fix migrate_vma_setup() src_owner and normal pages
  nouveau: fix migrate page regression
  nouveau: fix mixed normal and device private page migration
  mm/hmm: fix test timeout on slower machines
  mm/hmm/test: remove redundant page table invalidate
  mm/hmm: test mixed normal and device private migrations
  nouveau: make nvkm_vmm_ctor() and nvkm_mmu_ptp_get() static
  nouveau/hmm: fault one page at a time
  mm/hmm: add output flag for compound page mapping
  nouveau/hmm: support mapping large sysmem pages
  hmm: add tests for HMM_PFN_COMPOUND flag
  mm/hmm: optimize migrate_vma_setup() for holes
  mm: support THP migration to device private memory
  mm/thp: add THP allocation helper
  mm/hmm/test: add self tests for THP migration
  nouveau: support THP migration to private memory
