[PATCH 0/6] nouveau/hmm: add support for mapping large pages
hmm_range_fault() returns an array of page frame numbers and flags for
how the pages are mapped in the requested process' page tables. The PFN
can be used to get the struct page with hmm_pfn_to_page() and the page size
order can be determined with compound_order(page) but if the page is larger
than order 0 (PAGE_SIZE), there is no indication that the page is mapped
using a larger page size. To

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