Log:
Determine whether the MMU hardware is capable of updating a page table
entry's access flag and dirty state, and enable this feature when it's
available.
Am I right in thinking that this should result in improved performance under
load? (I'm wondering if it's time to redo my amd64 vs arm64 EC2 benchmarks.)
Yes, a modest one.
