Repply this change with a couple of bugs fixed:

- Do away with separate pool_cache for some kernel objects that have no special
  requirements and use the general purpose allocator instead. On one of my
  test systems this makes for a small (~1%) but repeatable reduction in system
  time during builds presumably because it decreases the kernel's cache /
  memory bandwidth footprint a little.
- vfs_lockf: cache a pointer to the uidinfo and put mutex in the data segment.

uvm(9): One rndsource for faults -- not one per CPU.

All relevant state is per-CPU anyway; the only substantive difference
this makes is how many entries appear in `rndctl -l' output and what
they are called -- formerly the somewhat confusing `cpuN', meaning
`page faults on cpuN', and now just `uvmfault'.  I don't think
there's any real value in being able to enable or disable measurement
or counting of page faults on one CPU vs others, so although this
could be a minor compatibility change, it's hard to imagine it
matters much.

In uvmpd_tryownerlock(), if the initial try-lock of the owner lock fails
then rather than do more try-locks and eventually sleep for a tick,
take a hold on the current owner's lock, drop the page interlock,
and acquire the lock that we took the hold on in a blocking fashion.
After we get the lock, check if the lock that we acquired is still
the lock for the owner of the page that we're interested in.
If the owner hasn't changed then can proceed with this page,
otherwise we will skip this page and move on to a different page.
This dramatically reduces the amount of time that the pagedaemon
sleeps trying to get locks, since even 1 tick is an eternity to sleep
in this context and it was easy to trigger that case in practice,
and with this new method the pagedaemon only very rarely actually blocks
to acquire the lock that it wants since the object locks are adaptive,
and when the pagedaemon does block then the amount of time it spends
sleeping will be generally be much less than 1 tick.

Add a new, more aggressive allocator for uvm_pglistalloc() to allocate
contiguous physical pages, and try this new allocator if the existing
one fails.  The existing contig allocator only tries to allocate pages
that are already free, which works fine shortly after boot but rarely
works after the system has been up for a while.  The new allocator uses
the pagedaemon to evict pages from memory in the hope that this will
free up a range of pages that satisfies the constraits of the request.
This should help with things like plugging in a USB device, which often
fails for some USB controllers because they can't get contigous memory.

Remove emap support. Unfortunately it never got to state where it would be
used and usable, due to reliability and limited & complicated MD support.

Going forward, we need to concentrate on interface which do not map anything
into kernel in first place (such as direct map or KVA-less I/O), rather
than making those mappings cheaper to do.

Remove uarea swap-out functionality:

- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Ephemeral mapping (emap) implementation.  Concept is based on the idea that
activity of other threads will perform the TLB flush for the processes using
emap as a side effect.  To track that, global and per-CPU generation numbers
are used.  This idea was suggested by Andrew Doran; various improvements to
it by me.  Notes:

- For now, zero-copy on pipe is not yet enabled.
- TCP socket code would likely need more work.
- Additional UVM loaning improvements are needed.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM.  Machine-dependent code is
responsible for initializing them before main() is called.  Anything
that steals KVA must adjust these variables accordingly.

This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().

This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.

This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

Fix the following pathological scanario:
* User allocates ZFOD region, but does not actually touch the buffer
  to fault in the pages.
* In a loop, user writes this buffer to a network socket, triggering
  sosend_loan().
* uvm_loan() calls uvm_loanzero() once for each page in the loaned
  region (since the pages have not yet faulted in).  This causes a
  page to be allocated and zero'd.  The result is the kernel spends
  a lot of time allocating and zero'ing pages.

This fixes creates a special object which owns a single zero'd page.
This single zero'd page is used to satisfy all loans of non-resident
ZFOD mappings.

Thanks to Allen Briggs for discovering the problem and for providing
an initial patch.
