Subject: [PATCH 0/5] Fix incorrect access of hugetlb pte entries
Date: Thu, 25 Jun 2026 11:29:49 +0000	[thread overview]
Message-ID: <20260625112955.3254283-1-dev.jain@arm.com> (raw)

There are various places which use ptep_get() to get the pte entry
corresponding to a hugetlb folio. Some arches have special handling
to compute the pteval, so they provide huge_ptep_get(). Use this
helper consistently.

Dev Jain (5):
  mm/rmap: use huge_ptep_get() in try_to_unmap_one()
  mm/rmap: use huge_ptep_get() in try_to_migrate_one()
  mm/migrate: use huge_ptep_get() in remove_migration_pte()
  mm/page_vma_mapped: use huge_ptep_get() for hugetlb
  mm/mprotect: use huge_ptep_get() for hugetlb
