Change Details

On amd64, don't abort promotion due to a missing accessed bit in a mapping before possibly write protecting that mapping. Previously, in some cases, we might not repromote after madvise(MADV_FREE) because there was no write fault to trigger the repromotion. Conversely, on arm64, don't pointlessly, yet harmlessly, write protect physical pages that aren't part of the physical superpage. Don't count aborted promotions due to explicit promotion prohibition (arm64) or hardware errata (amd64) as ordinary promotion failures.
