uvm_phys_to_vm_page() turns out to be a fairly central routine due to the
way that some of the pmaps work, so try to optimise it a little.

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.

ddb/db_active.h: New home for extern db_active.

This can be included unconditionally, and db_active can then be
queried unconditionally; if DDB is not in the kernel, then db_active
is a constant zero.  Reduces need for #include opt_ddb.h, #ifdef DDB.

Move the handling of PG_PAGEOUT from uvm_aio_aiodone_pages() to
uvm_page_unbusy() so that all callers of uvm_page_unbusy() don't need to
handle this flag separately.  Split out the pages part of uvm_aio_aiodone()
into uvm_aio_aiodone_pages() in rump just like in the real kernel.

In ZFS functions that can fail to copy data between the ARC and VM pages,
use uvm_aio_aiodone_pages() rather than uvm_page_unbusy() so that we can
handle these "I/O" errors.  Fixes PR 55702.

fix an incorrect assertion in the previous commit.

update the rump copy of uvm_page_unbusy() to match the real version,
in particular handle PG_PAGEOUT.  fixes a few atf tests.
the busypage test is buggy, expect it to fail.

make rump's uvm_aio_aiodone_pages() look more like the kernel version.
fixes some more rumpy assertions.

for the busypage test, replace atf_tc_expect_fail() with atf_tc_skip()
because atf apparently has no way to expect a test program to crash.

In the current code, CPU_COUNT_FREEPAGES counts pages in the global
freelists AND the per-CPU pgflcache free pages caches, and that is the
number of pages that the pagedaemon considers to be available.
However, most pages in the pgflcache per-CPU free page caches are NOT
actually available for any particular allocation, and thus allocating
a page can fail even though the pagedaemon thinks enough pages are
available.  This change makes CPU_COUNT_FREEPAGES only count pages in
the global freelists and not pages in the pgflcache per-CPU free page
caches, thus better aligning the pagedaemon's view of how many pages
are available with the number of pages that can actually be allocated
by any particular request.  This fixes a hang that Christos was hitting.

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.

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 nothing.  Remove this and get back all the bits in pg->pqflags.

- Many small tweaks to the SMT awareness in the scheduler.  It does a much
  better job now at keeping all physical CPUs busy, while using the extra
  threads to help out.  In particular, during preempt() if we're using SMT,
  try to find a better CPU to run on and teleport curlwp there.

- Change the CPU topology stuff so it can work on asymmetric systems.  This
  mainly entails rearranging one of the CPU lists so it makes sense in all
  configurations.

- Add a parameter to cpu_topology_set() to note that a CPU is "slow", for
  where there are fast CPUs and slow CPUs, like with the Rockwell RK3399.
  Extend the SMT awareness to try and handle that situation too (keep fast
  CPUs busy, use slow CPUs as helpers).

Page allocator:

The method for assigning pages to buckets in the non-NUMA case sucks.  It
can defeat memory interleaving in the hardware, and not distribute pages
fairly by colour.  To fix this and make things more deterministic, take the
physical PFN and colour into account.

Then when freeing pages, in the non-NUMA case don't change the page's bucket
either.  Keeping the bucket number stable will also permit partitioning page
replacement state by CPU package / NUMA node.

- 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.

Redo the page allocator to perform better, especially on multi-core and

- add rudimentary NUMA support - needs more work.
- remove now unused "listq" from vm_page.

uvm_pagealloc_strat(): Tweak the locking to allow for lazy dequeue of pages
in the pdpolicy code.  This means taking pg->interlock if assigning to
an object.  The remaining barrier to lazy dequeue is having a dedicated
TAILQ_ENTRY in the page (it's currently shared with the page allocator).

Fix programming mistake: 'paddrp' is a pointer given as argument, setting
it to NULL in the called function does not set it to NULL in the caller.

Actually, the callers of these functions do not do anything with the
special error handling, so drop the unused checks and the NULL assignments
altogether.

Avoid a panic from the sequence

	mlock(buf, 0);
	munlock(buf, 0);
	mlock(buf, page);
	munlock(buf, page);

where buf is page aligned, and page is actually anything > 0
(but not too big) which will get rounded up to the next multiple
of the page size.

In that sequence, it is possible that the 1st munlock() is optional.

Add a KASSERT() (or two) to detect the first effects of the problem
(without that, or in !DIAGNOSTIC kernels) the problem eventually
causes some kind of problem or other (most often still a panic.)

After this, mlock(anything, 0) (or munlock) validates "anything"
but is otherwise a no-op (regardless of the alignment of anything).

Also, don't treat mlock(buf, verybig) as equivalent to mlock(buf, 0)
which is (more or less) what we had been doing.

Update the kernhist(9) kernel history code to address issues identified
in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in
   the kernel and in the structures used for exporting the history data
   to userland via sysctl(9).  This avoids problems on some architectures
   where passing a 64-bit (or larger) value to printf(3) can cause it to
   process the value as multiple arguments.  (This can be particularly
   problematic when printf()'s format string is not a literal, since in
   that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to
   include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings
   updated.  Each format specifier now includes an explicit length
   modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings
   updated to replace uses of "%p" with "%#jx", and the pointer
   arguments are now cast to (uintptr_t) before being subsequently cast
   to (uintmax_t).  This is needed to avoid compiler warnings about
   casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or
   "%c" format strings replaced with numeric formats; several instances
   of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the
   history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with
   the -u option does not exist (previously, this condition was silently
   ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the
   data exported via sysctl(9) and exits if they do not match the values
   with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional
   requirements imposed on the format strings, along with several other
   minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example,
     uint64_t) for the history arguments.  But that would require another
     "rototill" of all the users in the future when we add support for an
     architecture that supports a larger size.  Also, the printf(3)
format
     specifiers for explicitly-sized values, such as "%"PRIu64, are much
     more verbose (and less aesthetically appealing, IMHO) than simply
     using "%ju".
[2] I've tried very hard to find "all [the] existing users of
kernhist(9)"
     but it is possible that I've missed some of them.  I would be glad
to
     update any stragglers that anyone identifies.
--
For some reason this single kernel seems to have outgrown its declared
size as a result of the kernhist(9) changes.  Bump the size.
XXX The amount of increase may be excessive - anyone with more detailed
XXX knowledge please feel free to further adjust the value
appropriately.
--
Misssed one cast of pointer --> uintptr_t in previous kernhist(9) commit
--
And yet another one.  :(
--

--
More improvements in grammar and readability.
--

probably needed.
--
And replace an instance of "%p" conversion with "%#jx"
--
Whitespace fix. Give Bl tag table a width. Fix Xr.

Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
   RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
   and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
   places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
   that had stubbed out code, other minor cleanups.

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.

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.

Be a little more friendly to dynamic physical segment registration.

Maintain an array of pointer to struct vm_physseg, instead of struct
array.  So that VM subsystem can take its pointer safely.  Pointer
to this struct will replace raw paddr_t usage in the future.

Dynamic removal is not supported yet.

Only MD data structure changes, no kernel bump needed.

Tested on i386, amd64, powerpc/ibm40x, arm11.

Abstraction fix; move physical address -> physical segment "reverse"
lookup code from uvm_page.h to uvm_page.c.

This code is used by some pmaps to lookup per-page state (PV) from
per-segment metadata (struct vm_physseg).  This is not needed if
UVM looks up physical segment once in fault handler, then directly
passes it to pmap.  This change helps transition to that model.

The only users of vm_physseg_find() are pmap_motorola.c and
powerpc/ibm4xx/pmap.c.

Remove PQ_FIXED, which means that page daemon doesn't need to know

Fixes/improvements to RB-tree implementation:
1. Fix inverted node order, so that negative value from comparison operator
   would represent lower (left) node, and positive - higher (right) node.
2. Add an argument (i.e. "context"), passed to comparison operators.
3. Change rb_tree_insert_node() to return a node - either inserted one or
   already existing one.
4. Amend the interface to manipulate the actual object, instead of the
   rb_node (in a similar way as Patricia-tree interface does).
5. Update all RB-tree users accordingly.

XXX: Perhaps rename rb.h to rbtree.h, since cleaning-up..

After much consideration, rename bus_space_physload_direct(9) back to
bus_space_physload_device(9).

The latter registers a segment as "device pages".  "Device pages" are
managed, but not used for general purpose memory.  Most typically XIP
pages.

- Use ctob() instead of ptoa() to obtain physical addresses from frame
numbers. Using ptoa() will cast to vaddr_t, which might no be adequate
for architectures where sizeof(paddr_t) > sizeof(vaddr_t) (like i386 PAE).

- small fix inside AGP heuristics to avoid masking high order bits for
systems with more than 4GB.

range of a device, similar to uvm_page_physload() for memories.  For now,
this is supposed to be called by MD code.  We have to consider the design

Because it knows if a given vnode is a device page (and its physical

-fix two conditions where PQ_FREE was still/already set while the page
 was not anymore/yet on the freelist and uvm_fpageqlock was not held
-clear PQ_FREE while the page is in the works of pageidlezero
This avoids that the DMA memory allocator (pglistalloc) grabs a page
which is not on the freelist, leading to a diagnostic panic (with DEBUG)
or freelist corruption. (mostly on X server activation after a VT
switch or suspend/resume because this can allocate megabytes of AGP
memory)
This might fix PR port-i386/38989 by Alan Barrett (in case this was

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,

Tweak the way the pagesize-related variables are set:
* Remove DEFAULT_PAGE_SIZE.  We don't use PAGE_SIZE the way Mach did.
* In uvm_setpagesize(), if we are called with uvmexp.pagesize == 0,
  then assert that PAGE_SIZE != 0 (i.e. a constant), and set uvmexp.pagesize
  accordingly.
* Provide defaults for MIN_PAGE_SIZE and MAX_PAGE_SIZE if not defined
  by <machine/vmparam.h>.  If PAGE_SIZE is not a constant, MIN_PAGE_SIZE
  and MAX_PAGE_SIZE must be provided.
* If MIN_PAGE_SIZE and MAX_PAGE_SIZE are not equal (i.e. PAGE_SIZE may
  not be a constant in all configurations), then ensure that PAGE_SIZE
  and friends expand to variable references for LKMs.

Add code to UBCify LFS.  This is still behind "#ifdef LFS_UBC" for now
(there are still some details to work out) but expect that to go
away soon.  To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:

* Create a writer daemon kernel thread whose purpose is to handle page
  writes for the pagedaemon, but which also takes over some of the
  functions of lfs_check().  This thread is started the first time an
  LFS is mounted.

* Add a "flags" parameter to GOP_SIZE.  Current values are
  GOP_SIZE_READ, meaning that the call should return the size of the
  in-core version of the file, and GOP_SIZE_WRITE, meaning that it
  should return the on-disk size.  One of GOP_SIZE_READ or
  GOP_SIZE_WRITE must be specified.

* Instead of using malloc(...M_WAITOK) for everything, reserve enough
  resources to get by and use malloc(...M_NOWAIT), using the reserves if
  necessary.  Use the pool subsystem for structures small enough that
  this is feasible.  This also obsoletes LFS_THROTTLE.

And a few that are not strictly necessary:

* Moves the LFS inode extensions off onto a separately allocated
  structure; getting closer to LFS as an LKM.  "Welcome to 1.6O."

* Unified GOP_ALLOC between FFS and LFS.

* Update LFS copyright headers to correct values.

* Actually cast to unsigned in lfs_shellsort, like the comment says.

* Keep track of which segments were empty before the previous
  checkpoint; any segments that pass two checkpoints both dirty and
  empty can be summarily cleaned.  Do this.  Right now lfs_segclean
  still works, but this should be turned into an effectless
  compatibility syscall.

Add extensible malloc types, adapted from FreeBSD.  This turns
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

 - fix uvm_km_pgremove() to always free any swap space associated with

 - get rid of UVM_LOAN_WIRED flag.  instead, we just make sure that
   pages loaned to the kernel are never on the page queues.

   at the same time.
 - add yet more assertions.

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.

Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Support dynamic sizing of the page color bins.  We also support
dynamically re-coloring pages; as machine-dependent code discovers
the size of the system's caches, it may call uvm_page_recolor() with
the new number of colors to use.  If the new mumber of colors is
smaller (or equal to) the current number of colors, then uvm_page_recolor()
is a no-op.

The system defaults to one bucket if machine-dependent code does not
initialize uvmexp.ncolors before uvm_page_init() is called.

Note that the number of color bins should be initialized to something
reasonable as early as possible -- for many early memory allocations,
we live with the consequences of the page choice for the lifetime of
the boot.

Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

add UBC memory-usage balancing.  we track the number of pages in use for
each of the basic types (anonymous data, executable image, cached files)
and prevent the pagedaemon from reusing a given page if that would reduce
the count of that type of page below a sysctl-setable minimum threshold.
the thresholds are controlled via three new sysctl tunables:
vm.anonmin, vm.vnodemin, and vm.vtextmin.  these tunables are the
percentages of pageable memory reserved for each usage, and we do not allow
the sum of the minimums to be more than 95% so that there's always some
memory that can be reused.

First sweep at scheduler state cleanup.  Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

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.

Since interrupts must be blocked while this lock is asserted, tying them

Make a slight modification of pmap_growkernel() -- it now returns the

Also, export uvm_maxkaddr so that uvm_pageboot_alloc() can grow the
kernel pmap if necessary, as well.  Note that pmap_growkernel() must
now be able to handle being called before pmap_init().

Add a new `access type' argument to pmap_enter().  This indicates what type of
memory access a mapping was caused by.  This is passed through from uvm_fault()
and udv_fault(), and in most other cases is 0.
The pmap module may use this to preset R/M information.  On MMUs which require
R/M emulation, the implementation may preset the bits and avoid taking another
fault.  On MMUs which keep R/M information in hardware, the implementation may
preset its cached bits to speed up the next call to pmap_is_modified() or
pmap_is_referenced().

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
they will only be used by machine-dependent code (e.g. for loading the
vm_physsegs).

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
