arm64: Implement pmdp_set_access_flags() for hardware AF/DBM
commit 282aa7051b0169991b34716f0f22d9c2f59c46c4 upstream.
The update to the accessed or dirty states for block mappings must be
done atomically on hardware with support for automatic AF/DBM. The
ptep_set_access_flags() function has been fixed as part of commit
66dbd6e61a52 ("arm64: Implement ptep_set_access_flags() for hardware
AF/DBM"). This patch brings pmdp_set_access_flags() in line with the pte
counterpart.
Fixes: 2f4b829c625e ("arm64: Add support for hardware updates of the access and dirty pte bits")
