Subject: [PATCH v8 0/3] Speedup mremap on ppc64
Date: Wed, 16 Jun 2021 10:27:32 +0530 [thread overview]
Message-ID: <20210616045735.374532-1-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.
This patchset is dependent on
https://lore.kernel.org/linux-mm/20210616045239.370802-1-aneesh.kumar@linux.ibm.com/
Changes from v7:
* Split mremap fixes to a separate series
Changes from v6:
* Update ppc64 flush_tlb_range to invalidate page walk cache.
* Add patches to fix race between mremap and page out
* Add patch to fix build error with page table levels 2
Changes from v5:
* Drop patch mm/mremap: Move TLB flush outside page table lock
* Add fixes for race between optimized mremap and page out
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
