This patch series is split out series from [PATCH v7 00/11] Speedup mremap on ppc64
(https://lore.kernel.org/linux-mm/20210607055131.156184-1-aneesh.kumar@linux.ibm.com)
dropping ppc64 specific changes.

I will send the ppc64 specific changes separately once we agree on how to handle the
TLB flush changes.


Aneesh Kumar K.V (6):
  selftest/mremap_test: Update the test to handle pagesize other than 4K
  selftest/mremap_test: Avoid crash with static build
  mm/mremap: Convert huge PUD move to separate helper
  mm/mremap: Don't enable optimized PUD move if page table levels is 2
  mm/mremap: Use pmd/pud_poplulate to update page table entries
  mm/mremap: hold the rmap lock in write mode when moving page table
    entries.
