Sorry for the bugginess that slipped through my testing in v1.
I think this series addresses all of the reported problems.
v2:
- Add "alpha: Fix alloc_zeroed_user_highpage_movable()"
- Rework the shmem_alloc_page() -> shmem_alloc_folio() conversion to
be less disruptive (and buggy)
- Use folio_test_pmd_mappable() instead of folio_test_large() to
fix the !THP builds
- Initialise 'folio' to NULL in shmem_swapin_folio to fix the error
case
- Avoid using HPAGE_PMD_NR in shmem_getpage_gfp()
- Remove BUILD_BUG from can_split_folio()
- Add the mm parts needed to convert ->migratepage to migrate_folio
for fs in the next merge window
v1:
- Finish the conversion from alloc_pages_vma() to vma_alloc_folio()
- Finish converting shrink_page_list() to folios
- Start converting shmem from pages to folios (alas, not finished,
I have simply run out of time with all the debugging/fixing needed
for 5.18)
