Start trying to reduce cache misses on vm_page during fault processing. - Make PGO_LOCKED getpages imply PGO_NOBUSY and remove the latter. Mark pages busy only when there's actually I/O to do. - When doing COW on a uvm_object, don't mess with neighbouring pages. In all likelyhood they're already entered. - Don't mess with neighbouring VAs that have existing mappings as replacing those mappings with same can be quite costly. - Don't enqueue pages for neighbour faults unless not enqueued already, and don't activate centre pages unless uvmpdpol says its useful. Also: - Make PGO_LOCKED getpages on UAOs work more like vnodes: do gang lookup in the radix tree, and don't allocate new pages. - Fix many assertion failures around faults/loans with tmpfs.

UVM locking changes, proposed on tech-kern: - Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock. - Break v_interlock and vmobjlock apart. v_interlock remains a mutex. - Do partial PV list locking in the x86 pmap. Others to follow later.

- Add and use wrapper functions that take and acquire page interlocks, and pairs of page interlocks. Require that the page interlock be held over calls to uvm_pageactivate(), uvm_pagewire() and similar. - Solve the concurrency problem with page replacement state. Rather than updating the global state synchronously, set an intended state on individual pages (active, inactive, enqueued, dequeued) while holding the page interlock. After the interlock is released put the pages on a 128 entry per-CPU queue for their state changes to be made real in batch. This results in in a ~400 fold decrease in contention on my test system. Proposed on tech-kern but modified to use the page interlock rather than atomics to synchronise as it's much easier to maintain that way, and cheaper.

pagedaemon: - Use marker pages to keep place in the queue when scanning, rather than relying on assumptions. - In uvmpdpol_balancequeue(), lock the object once instead of twice. - When draining pools, the situation is getting desperate, but try to avoid saturating the system with xcall, lock and interrupt activity by sleeping for 1 clock tick if being continually awoken and all pools have been cycled through at least once. - Pause & resume the freelist cache during pool draining.
