could only happen for the last page, because only then buffer which
triggered invalidation could not cover the whole page.

This should be updated by developers who know more about this system than

to not get scanned on boot.
The problem originated in change 253549. With the change to the mps(4)
driver to scan only targets that it knows it has (as opposed to scanning
the entire bus), scanning RAID volumes on boot was omitted.
So, for versions of FreeBSD that have the scanning changes
(__FreeBSD_version 1000039 and higher), scan RAID volumes that are added
whether or not we're booting.

amount of free memory was close to the point at which we would begin
reclaiming pages. Now, we continuously scan the active page queue,
regardless of the amount of free memory. Consequently, we are continuously
calling pmap_ts_referenced() on active pages.
Prior to this change, pmap_ts_referenced() would always demote superpage
mappings in order to obtain finer-grained reference information. This made
sense because we were coming under memory pressure and would soon have to
begin reclaiming pages. Now, however, with continuous scanning of the
active page queue, these demotions are taking a toll on performance. To
address this problem, I have replaced the demotion with a heuristic for
periodically clearing the reference flag on superpage mappings.
