  arm64: mm: Always make sw-dirty PTEs hw-dirty in pte_modify (2023-12-12 16:25:26 +0000)

----------------------------------------------------------------
arm64 fixes:

- Arm CMN perf: fix the DTC allocation failure path which can end up
  erroneously clearing live counters

- arm64/mm: fix hugetlb handling of the dirty page state leading to a
  continuous fault loop in user on hardware without dirty bit management
  (DBM). That's caused by the dirty+writeable information not being
  properly preserved across a series of mprotect(PROT_NONE),
  mprotect(PROT_READ|PROT_WRITE)
