Subject: [PATCH v2 00/13] mm/debug_vm_pgtable fixes
Date: Wed, 19 Aug 2020 18:30:54 +0530 [thread overview]
Message-ID: <20200819130107.478414-1-aneesh.kumar@linux.ibm.com> (raw)
This patch series includes fixes for debug_vm_pgtable test code so that
they follow page table updates rules correctly. The first two patches introduce
changes w.r.t ppc64. The patches are included in this series for completeness. We can
merge them via ppc64 tree if required.
Hugetlb test is disabled on ppc64 because that needs larger change to satisfy
page table update rules.
Changes from V1:
* Address review feedback
* drop test specific pfn_pte and pfn_pmd.
* Update ppc64 page table helper to add _PAGE_PTE
Aneesh Kumar K.V (13):
powerpc/mm: Add DEBUG_VM WARN for pmd_clear
powerpc/mm: Move setting pte specific flags to pfn_pte
mm/debug_vm_pgtable/ppc64: Avoid setting top bits in radom value
mm/debug_vm_pgtables/hugevmap: Use the arch helper to identify huge
vmap support.
mm/debug_vm_pgtable/savedwrite: Enable savedwrite test with
CONFIG_NUMA_BALANCING
mm/debug_vm_pgtable/THP: Mark the pte entry huge before using
set_pmd/pud_at
mm/debug_vm_pgtable/set_pte/pmd/pud: Don't use set_*_at to update an
existing pte entry
mm/debug_vm_pgtable/thp: Use page table depost/withdraw with THP
mm/debug_vm_pgtable/locks: Move non page table modifying test together
mm/debug_vm_pgtable/locks: Take correct page table lock
mm/debug_vm_pgtable/pmd_clear: Don't use pmd/pud_clear on pte entries
mm/debug_vm_pgtable/hugetlb: Disable hugetlb test on ppc64
mm/debug_vm_pgtable: populate a pte entry before fetching it
