Will Deacon bf950040a5 arm64: pgtable: use a single bit for PTE_WRITE regardless of DBM ... Depending on CONFIG_ARM64_HW_AFDBM, we use either bit 57 or 51 of the pte to represent PTE_WRITE. Given that bit 51 is reserved prior to ARMv8.1, we can just use that bit regardless of the config option. That also matches what happens if a kernel configured with ARM64_HW_AFDBM=y is run on a CPU without the DBM functionality.
