c15541e7a7 contigalloc doesn't place the allocated page(s) into an object, and
now this breaks vm_page_wire (due to wired page accounting per object.)

This should fix a problem as described by Donald Maddox.

eaf13dd73a Change the busy page mgmt, so that when pages are freed, they
MUST be PG_BUSY.  It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed.  The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use.  There were some minor problems
with the collapse code, and this plugs those subtile "holes."

Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages.  I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise.  For now, we are stuck
with the current morass.

If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.

If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard

c3229e05a3 Improved connection establishment performance by doing local port lookups via
a hashed port list. In the new scheme, in_pcblookup() goes away and is
replaced by a new routine, in_pcblookup_local() for doing the local port
check. Note that this implementation is space inefficient in that the PCB
struct is now too large to fit into 128 bytes. I might deal with this in the
future by using the new zone allocator, but I wanted these changes to be
extensively tested in their current form first.

Also:
1) Fixed off-by-one errors in the port lookup loops in in_pcbbind().
2) Got rid of some unneeded rehashing. Adding a new routine, in_pcbinshash()
   to do the initialial hash insertion.
3) Renamed in_pcblookuphash() to in_pcblookup_hash() for easier readability.
4) Added a new routine, in_pcbremlists() to remove the PCB from the various
   hash lists.
5) Added/deleted comments where appropriate.
6) Removed unnecessary splnet() locking. In general, the PCB functions should
   be called at splnet()...there are unfortunately a few exceptions, however.
7) Reorganized a few structs for better cache line behavior.
8) Killed my TCP_ACK_HACK kludge. It may come back in a different form in
   the future, however.

These changes have been tested on wcarchive for more than a month. In tests
done here, connection establishment overhead is reduced by more than 50
times, thus getting rid of one of the major networking scalability problems.

Still to do: make tcp_fastimo/tcp_slowtimo scale well for systems with a
large number of connections. tcp_fastimo is easy; tcp_slowtimo is difficult.

WARNING: Anything that knows about inpcb and tcpcb structs will have to be
         recompiled; at the very least, this includes netstat(1).

88a92ff10e Even though BIOS writer's guide recommends cpuid instruction of Cyrix
6x86MX CPU is enabled (BIOS should not disable it), some BIOS disables
it via CCR4.  In this case, cpu variable becomes CPU_486 and
identblue() is called.  Because Cyrix 6x86MX has MSR and doesn't have
MSR1002, wrmsr instruction generates general protection fault.

2d8acc0f4a VM level code cleanups.
1)	Start using TSM.
	Struct procs continue to point to upages structure, after being freed.
	Struct vmspace continues to point to pte object and kva space for kstack.
	u_map is now superfluous.
2)	vm_map's don't need to be reference counted.  They always exist either
	in the kernel or in a vmspace.  The vmspaces are managed by reference
	counts.
3)	Remove the "wired" vm_map nonsense.
4)	No need to keep a cache of kernel stack kva's.
5)	Get rid of strange looking ++var, and change to var++.
6)	Change more data structures to use our "zone" allocator.  Added
	struct proc, struct vmspace and struct vnode.  This saves a significant
	amount of kva space and physical memory.  Additionally, this enables
	TSM for the zone managed memory.
7)	Keep ioopt disabled for now.
8)	Remove the now bogus "single use" map concept.
9)	Use generation counts or id's for data structures residing in TSM, where
	it allows us to avoid unneeded restart overhead during traversals, where
	blocking might occur.
10)	Account better for memory deficits, so the pageout daemon will be able
	to make enough memory available (experimental.)
11)	Fix some vnode locking problems. (From Tor, I think.)
12)	Add a check in ufs_lookup, to avoid lots of unneeded calls to bcmp.
	(experimental.)
13)	Significantly shrink, cleanup, and make slightly faster the vm_fault.c
	code.  Use generation counts, get rid of unneded collpase operations,
	and clean up the cluster code.
14)	Make vm_zone more suitable for TSM.

This commit is partially as a result of discussions and contributions from
other people, including DG, Tor Egge, PHK, and probably others that I
have forgotten to attribute (so let me know, if I forgot.)

This is not the infamous, final cleanup of the vnode stuff, but a necessary
step.  Vnode mgmt should be correct, but things might still change, and
there is still some missing stuff (like ioopt, and physical backing of
non-merged cache files, debugging of layering concepts.)

764d8cef56 A more complete fix for the "land" attack, removing the "quick fix" from
rev 1.66.  This fix contains both belt and suspenders.

Belt: ignore packets where src == dst and srcport == dstport in TCPS_LISTEN.
 These packets can only legitimately occur when connecting a socket to itself,
 which doesn't go through TCPS_LISTEN (it goes CLOSED->SYN_SENT->SYN_RCVD->
 ESTABLISHED).  This prevents the "standard" "land" attack, although doesn't
 prevent the multi-homed variation.

Suspenders: send a RST in response to a SYN/ACK in SYN_RECEIVED state.
 The only packets we should get in SYN_RECEIVED are
 1. A retransmitted SYN, or
 2. An ack of our SYN/ACK.
 The "land" attack depends on us accepting our own SYN/ACK as an ACK;
 in SYN_RECEIVED state; this should prevent all "land" attacks.

We also move up the sequence number check for the ACK in SYN_RECEIVED.
 This neither helps nor hurts with respect to the "land" attack, but
 puts more of the validation checking in one spot.

3ae6029808 - Move SETKLOC and CLEARKLOCK macros into uion.h.
- Set UN_ULOCK in union_lock() when UN_KLOCK is set.  Caller expects
  that vnode is locked correctly, and may call another function which
  expects locked vnode and may unlock the vnode.
- Do not assume the behavior of inside functions in FreeBSD's
  vfs_suber.c is same as 4.4BSD-Lite2.  Vnode may be locked in
  vget() even though flag is zero.  (Locked vnode is, of course,
  unlocked before returning from vget.)

Move sigjmp_buf and jmp_buf structure definitions to machine/setjmp.h
so that i386 can continue to use int as the basic register type and
alpha can use long. Bruce was concerned about possible differing
alignment. I've left the definition of _JBLEN in machine/setjmp.h
even though Bruce's example used the number directly. I don't know if
any other code relies on _JBLEN, so I left it to avoid potential
breakage.

  `accents'.  If the next key is the space key, produce the accent char
  itself.  Otherwise search the accent key map entry, indexed by
  `accents', for a matching pair of a regular char and an accented char.
- Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP
  and GIO_DEADKEYMAP).

bf27292b35 Turn off the VTEXT flag when an object is no longer referenced, so
that an executable that is no longer running can be written to.  Also,
clear the OBJ_OPT flag more often, when appropriate.

95e5e988e0 Make our v_usecount vnode reference count work identically to the
original BSD code.  The association between the vnode and the vm_object
no longer includes reference counts.  The major difference is that
vm_object's are no longer freed gratuitiously from the vnode, and so
once an object is created for the vnode, it will last as long as the
vnode does.

When a vnode object reference count is incremented, then the underlying
vnode reference count is incremented also.  The two "objects" are now
more intimately related, and so the interactions are now much less
complex.

When vnodes are now normally placed onto the free queue with an object still
attached.  The rundown of the object happens at vnode rundown time, and
happens with exactly the same filesystem semantics of the original VFS
code.  There is absolutely no need for vnode_pager_uncache and other
travesties like that anymore.

A side-effect of these changes is that SMP locking should be much simpler,
the I/O copyin/copyout optimizations work, NFS should be more ponderable,
and further work on layered filesystems should be less frustrating, because
of the totally coherent management of the vnode objects and vnodes.

Please be careful with your system while running this code, but I would
greatly appreciate feedback as soon a reasonably possible.
