Counter tweaks:

- Don't need to count anonpages+filepages any more; clean+unknown+dirty for
  each kind of page can be summed to get the totals.

- Track the number of free pages with a counter so that it's one less thing
  for the allocator to do, which opens up further options there.

- Remove cpu_count_sync_one().  It has no users and doesn't save a whole lot.
  For the cheap option, give cpu_count_sync() a boolean parameter indicating
  that a cached value is okay, and rate limit the updates for cached values
  to hz.

uvm_availmem(): give it a boolean argument to specify whether a recent
cached value will do, or if the very latest total must be fetched.  It can
be called thousands of times a second and fetching the totals impacts not
only the calling LWP but other CPUs doing unrelated activity in the VM
system.

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.

dropped, so it just doesn't matter.

uvmpdpol_pageactive(): the change to not re-activate recently activated
pages worked great with uvm_pageqlock, but it doesn't buy anything any more,
because now the busy pages are likely in a per-CPU queue somewhere waiting
to be processed, and changing the intent on those queued pages costs next
to nothing.  Remove this and get back all the bits in pg->pqflags.

- 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.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Reorganise UVM locking to protect P->V state and serialise pmap(9)
operations on the same page(s) by always locking their owner.  Hence
lock order: "vmpage"-lock -> pmap-lock.

Patch, proposed on tech-kern@, from Andrew Doran.
