Prevent accounting bug when an anon w/ swap slot is passed to uvm_anon_release() uvm_anon_release() is always called for anon that have an associated page so decrementing `uvmexp.swpgonly' is incorrect. This happened because the page was cleared before calling uvm_anfree(). Reported by many including mvs@, miod@ and robert@ ok kettenis@, miod@

Zap anon pages mappings in uvm_anon_release() instead of in the fault handler. This makes all code paths deactivating or freeing anons consistent. No objection from the usual suspects.

(re)Introduce locking for amaps & anons. A rwlock is attached to every amap and is shared with all its anon. The same lock will be used by multiple amaps if they have anons in common. This should be enough to get the upper part of the fault handler out of the KERNEL_LOCK() which seems to bring up to 20% improvements in builds. This is based/copied/adapted from the most recent work done in NetBSD which is an evolution of the precendent simple_lock scheme. Tested by many, thanks! ok kettenis@, mvs@

all pools have their ipl set via pool_setipl, so fold it into pool_init. the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);

Backout all changes to uvm after pmemrange (which will be backed out separately). a change at or just before the hackathon has either exposed or added a very very nasty memory corruption bug that is giving us hell right now. So in the interest of kernel stability these diffs are being backed out until such a time as that corruption bug has been found and squashed, then the ones that are proven good may slowly return. a quick hitlist of the main commits this backs out: mine: uvm_objwire the lock change in uvm_swap.c using trees for uvm objects instead of the hash removing the pgo_releasepg callback. art@'s: putting pmap_page_protect(VM_PROT_NONE) in uvm_pagedeactivate() since all callers called that just prior anyway. ok beck@, ariane@. prompted by deraadt@.

While splitting flags and pqflags might have been a good idea in theory to separate locking, on most modern machines this is not enough since operations on short types touch other short types that share the same word in memory. Merge pg_flags and pqflags again and now use atomic operations to change the flags. Also bump wire_count to an int and pg_version might go int as well, just for alignment. tested by many, many. ok miod@

Mechanically rename the "flags" and "version" fields in struct vm_page

Merge in the unified buffer cache code as found in NetBSD 2001/03/10. The code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>. Tested for the past few weeks by many developers, should be in a pretty stable state, but will require optimizations and additional cleanups.

Merge in -current from two days ago in the SMP branch. As usual with merges, they do not indicate progress, so do not hold your breath for working SMP, and do not mail me and ask about the state of it. It has not changed. There is work ongoing, but very, very slowly. The commit is done in parts as to not lock up the tree in too big chunks at a time.

Convert bzero to memset(X, 0..) and bcopy to memcpy. This is to match (make diffs smaller) the code in NetBSD. new gcc inlines those functions, so this could also be a performance win.
