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.
You need to break this up into parts that go where they need to
go. Nouveau rc changes should go to DRM or some series needs to
explain the linkage
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
Order things so it is hmm, test, noeveau
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
This is another series, you should split it even if it has to go
through the hmm tree

Thanks. I thought there was probably a better way to submit this but
I posted everything so people could see how it all fit together.
