Subject: [PATCH v5 0/9] Speedup mremap on ppc64
Date: Thu, 22 Apr 2021 11:13:14 +0530	[thread overview]
Message-ID: <20210422054323.150993-1-aneesh.kumar@linux.ibm.com> (raw)

Hi,

This patchset enables MOVE_PMD/MOVE_PUD support on power. This requires
the platform to support updating higher-level page tables without
updating page table entries. This also needs to invalidate the Page Walk
Cache on architecture supporting the same.

Changes from v4:
* Change function name and arguments based on review feedback.

Changes from v3:
* Fix build error reported by kernel test robot
* Address review feedback.

Changes from v2:
* switch from using mmu_gather to flush_pte_tlb_pwc_range() 

Changes from v1:
* Rebase to recent upstream
* Fix build issues with tlb_gather_mmu changes



Aneesh Kumar K.V (9):
  selftest/mremap_test: Update the test to handle pagesize other than 4K
  selftest/mremap_test: Avoid crash with static build
  mm/mremap: Use pmd/pud_poplulate to update page table entries
  powerpc/mm/book3s64: Fix possible build error
  powerpc/mm/book3s64: Update tlb flush routines to take a page walk
    cache flush argument
  mm/mremap: Use range flush that does TLB and page walk cache flush
  mm/mremap: Move TLB flush outside page table lock
  mm/mremap: Allow arch runtime override
  powerpc/mm: Enable move pmd/pud
