Subject: [PATCH 0/3] arm64 fixes following support for hardware AF/DBM

It seems that the recent patch for handling hardware updates to the AF
and dirty bits also breaks hardware without such feature because of
changes to how a pte is detected as dirty. The first patch fixes the
non-DBM hardware case. The second is fixes losing of the dirty
information for hardware DBM (as a consequence of the first patch,
otherwise a pte was pretty much always dirty anyway). The third patch is
a clean-up.

Catalin Marinas (2):
  arm64: Fix the pte_hw_dirty() check when AF/DBM is enabled
  arm64: Fix pte_modify() to preserve the hardware dirty information

Will Deacon (1):
  arm64: pgtable: use a single bit for PTE_WRITE regardless of DBM
