Subject: [PATCH v3 0/9] Speedup mremap on ppc64
Date: Tue, 30 Mar 2021 11:37:43 +0530 [thread overview]
Message-ID: <20210330060752.592769-1-aneesh.kumar@linux.ibm.com> (raw)
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 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
