- If the hardware provided NUMA info, then use it to decide how to set up
  the allocator's buckets, instead of doing round robin distribution.  There
  are open questions here but this is better than doing nothing.

- Kernel reserve pages are for the kernel not realtime threads.

Make page waits (WANTED vs BUSY) interlocked by pg->interlock.  Gets RW
locks out of the equation for sleep/wakeup, and allows observing+waiting
for busy pages when holding only a read lock.  Proposed on tech-kern.

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.

remove the aiodoned thread.  I originally added this to provide a thread context
for doing page cache iodone work, but since then biodone() has changed to
hand off all iodone work to a softint thread, so we no longer need the
special-purpose aiodoned thread.

- 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.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

move and rename the uvm history code out of uvm_stat to "kernhist".

rename "UVMHIST" option to enable the uvm histories.

TODO:
- make UVMHIST properly depend upon KERNHIST
- enable dynamic registration of histories.  this is mostly just
  allocating something in a bitmap, and is only for viewing multiple
  histories in a merged form.

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.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

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.

Proposed on <tech-kern>, silence there.

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Changes necessary to implement pre-zero'ing of pages in the idle loop:
- Make page free lists have two actual queues: known-zero pages and
  pages with unknown contents.
- Implement uvm_pageidlezero().  This function attempts to zero up to
  the target number of pages until the target has been reached (currently
  target is `all free pages') or until whichqs becomes non-zero (indicating
  that a process is ready to run).
- Define a new hook for the pmap module for pre-zero'ing pages.  This is
  used to zero the pages using uncached access.  This allows us to zero
  as many pages as we want without polluting the cache.

In order to use this feature, each platform must add the appropropriate
glue in their idle loop.

Instead of checking vm_physmem[<physseg>].pgs to determine if
uvm_page_init() has completed, add a boolean uvm.page_init_done,
and test against that.  Use this same boolean (rather than
pmap_initialized) in pmap_growkernel() to determine if we are
being called via uvm_page_init() to grow the kernel address space.

This fixes a problem on some i386 configurations where pmap_init()
itself was needing to have the kernel page table grown, and since
pmap_initialized was not yet set to TRUE, pmap_growkernel() was
choosing the wrong code path.

Fix tested by Havard Eidnes.

Add support for multiple memory free lists.  There is at least one
default free list, and 0 - N additional free list, in order of descending
priority.

A new page allocation function, uvm_pagealloc_strat(), has been added,
providing three page allocation strategies:

	- normal: high -> low priority free list walk, taking the
	  page off the first free list that has one.

	- only: attempt to allocate a page only from the specified free
	  list, failing if that free list has none available.

	- fallback: if `only' fails, fall back on `normal'.

uvm_pagealloc(...) is provided for normal use (and is a synonym for
uvm_pagealloc_strat(..., UVM_PGA_STRAT_NORMAL, 0); the free list argument
is ignored for the `normal' case).

uvm_page_physload() now specified which free list the pages will be
loaded onto.  This means that some platforms which have multiple physical
memory segments may define additional vm_physsegs if they wish to break
individual physical segments into differing priorities.

Machine-dependent code must define _at least_ the following constants
in <machine/vmparam.h>:

	VM_NFREELIST: the number of free lists the system will have

	VM_FREELIST_DEFAULT: the default freelist (should always be 0,
	but is defined in machdep code so that it's with all of the
	other free list-related constants).

Additional free list names may be defined by machine-dependent code, but
