PR kern/32166: pgo_get protocol is ambiguous
Also problems with tmpfs+nfs noted by hannken@.

Don't pass PGO_ALLPAGES to pgo_get, and ignore PGO_DONTCARE in the
!PGO_LOCKED case.  In uao_get() have uvm_pagealloc() take care of page
zeroing and release busy pages on error.

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.

Resurrect PGO_ZERO support.

When vnode pager encounters hole pages in XIP'ed vnodes, it fills
page slots with PGO_ZERO and returns them back to the caller (fault
handler).  Fault handlers are responsible to check page slots and
redirect PGO_ZERO to the single "zero page" allocated by calling
uvm_page_zeropage_alloc(9).

The zero page is wired, read-only (PG_RDONLY) page.  It's shared
by multiple vnodes, it has no single owner.

XIP'ed vnodes are supposed to be "stable" during I/O (unlocked).
Because XIP'ed mounts are always read-only.  There's no chance to
change mappings of XIP'ed vnodes and their XIP'ed pages.  Thus the
cached uobj is reused after pgo_get() for PGO_ZERO.

(Do we need a new concept of "read-only UVM object"?)

Add snapshot support for logging ffs file systems.

- Add UFS_WAPBL_BEGIN() / UFS_WAPBL_END() where needed.

- Expunge WAPBL log inodes from snapshots.

- Ffs_copyonwrite() and ffs_snapblkfree() must run inside a WAPBL transaction.

- Add ffs_gop_write() as a wrapper around genfs_gop_write() that makes sure
  genfs_gop_write() gets always called inside a WAPBL transaction.

- Add VOP_PUTPAGES() flag PGO_JOURNALLOCKED to tag calls to VOP_PUTPAGES()
  inside a WAPBL transaction.

Reviewed by: Simon Burge <simonb@netbsd.org>,  Greg Oster <oster@netbsd.org>

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.

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.

eliminate the VM_PAGER_* error codes in favor of the traditional E* codes.
the mapping is:

VM_PAGER_OK		        0
VM_PAGER_BAD		        <unused>
VM_PAGER_FAIL		        <unused>
VM_PAGER_PEND		        0 (see below)
VM_PAGER_ERROR		        EIO
VM_PAGER_AGAIN		        EAGAIN
VM_PAGER_UNLOCK		        EBUSY
VM_PAGER_REFAULT	        ERESTART

for async i/o requests, it used to be possible for the request to
be convert to sync, and the pager would return VM_PAGER_OK or VM_PAGER_PEND
to indicate whether the caller should perform post-i/o cleanup.
this is no longer allowed; pagers must now return 0 to indicate that
the async i/o was successfully started, and the caller never needs to
worry about doing the post-i/o cleanup.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some

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.  :-)
