Konstantin Belousov 872d995f76 Change the pmap_ts_referenced() method of amd64 pmap to use shared ... pvh_global_lock. This allows the method to be executed in parallel, avoiding undue contention on the pvh_global_lock for the multithreaded pagedaemon. The pmap_ts_referenced() function has to inspect the page mappings for several pmaps, which need to be locked while pv list lock is owned. This contradicts to the lock order, where pmap lock is before pv list lock. Introduce the generation count for the pv list of the page or superpage, which indicate any change in the pv list, and, as usual, perform restart of the iteration if generation changed while pv lock was dropped for blocking acquire of a pmap lock.
