8d7fd621d7 Don't acquire Giant just to call trap_fatal(), we are about to panic
anyway so we'd rather see the printf's then block if the system is
hosed.

9ff666d52d A feature to allow one to telnet to a unix domain socket. (MFC from
non-crypto version)

Also update the crypto telnet's man page to reflect other options
ported from the non-crypto version.

c6bb467070 - Assert Giant is held in the vnode pager methods.

  vnode_pager_lock().

f7df8897d2 - Add in several asserts of vm_mtx.
- Assert Giant in vm_pageout_scan() for the vnode hacking that it does.
- Don't hold vm_mtx around vget() or vput().
- Lock Giant when calling vm_pageout_scan() from the pagedaemon.  Also,
  lock curproc while setting the P_BUFEXHAUST flag.
- For now we still hold Giant for all of the vm_daemon.  When process
  limits are locked we will be only need Giant for swapout_procs().

7959aca6f7 - Assert that the vm lock is held for all of _vm_object_allocate().
- Restore the previous order of setting up a new vm_object.  The previous
  had a small bug where we zero'd out the flags after we set the
  OBJ_ONEMAPPING flag.
- Add several asserts of vm_mtx.
- Assert Giant is held rather than locking and unlocking it in a few
  places.
- Add in some #ifdef objlocks code to lock individual vm objects when
  vm objects each have their own lock someday.
- Don't bother acquiring the allproc lock for a ddb command.  If DDB
  blocked on the lock, that would be worse than having an inconsistent
  allproc list.

cf87d9f5db - Add lots of vm_mtx assertions.
- Add a few KTR tracepoints to track the addition and removal of
  vm_map_entry's and the creation adn free'ing of vmspace's.

  pointer to its new vmspace before freeing the old vmspace.

b6e2dc1111 - Lock the VM around the pmap_swapin_proc() call in faultin().
- Don't lock Giant in the scheduler() function except for when calling
  faultin().
- In swapout_procs(), lock the VM before the proccess to avoid a lock order
  violation.
- In swapout_procs(), release the allproc lock before calling swapout().
  We restart the process scan after swapping out a process.
- In swapout_procs(), un #if 0 the code to bump the vmspace reference count
  and lock the process' vm structures.  This bug was introduced by me and
  could result in the vmspace being free'd out from under a running
  process.
- Fix an old bug where the vmspace reference count was not free'd if we
  failed the swap_idle_threshold2 test.

7703731a60 - Obtain Giant in mmap() syscall while messing with file descriptors and
vnodes.
- Fix an old bug that would leak a reference to a fd if the vnode being
  mmap'd wasn't of type VREG or VCHR.
- Lock Giant in vm_mmap() around calls into the VM that can call into
  pager routines that need Giant or into other VM routines that need
  Giant.
- Replace code that used a goto to jump around the else branch of a test
  to use an else branch instead.

94feb0ab7e Tweak the xmphy driver a little bit based on something I learned about
the built-in 1000baseX interface in the Level 1 LXT1001 chip. The Level 1
PHY comes up with the isolate bit in the control register set by default,
but it also has the autonegotiate bit set. When you tell the xmphy driver
to select IFM_AUTO mode, it sees that the autoneg bit is already on, and
thus doesn't bother updating the control register. However this means that
the isolate bit is never turned off (unless you manually select 1000baseSX
full or half duplex mode, which does result in the control register being
modified and the ISO bit being turned off).

This subtle and unusual behavioral difference stopped me from being able
to receive packets on the SMC9462TX card for several days, since isolating
the PHY disconnects it from the MAC's data interface. The fix is to omit
the 'is the autoneg big set?' test, since it doesn't really provide much
of an optimization anyway.

This commit also updates the xmphy driver to support the Jato/Level 1
internal PHY. (I'm not sure how Jato Technologies is related to Level 1:
all I know is the OUI from the PHY ID registers maps to Jato in the OUI
database.) This will be used once I add the if_lge driver to support
the LXT10010 chip.

87198ba253 - Lock the VM when initializing the vmspace for proc0.

  the lookup anyways.

35be3f27b2 When a game ends that makes the top 10, the function insert_score in
score.c is called to make the new score file.  But the case for KFIRE
(killed by fire) incorrectly uses strcpy instead of strcat (all the
other cases use strcat).  This puts the string in the wrong place and
corrupts the score file.

2434332d91 Make sure that all resource allocation is handled in the pcib device, not
the chipset. This is already how the multi-hose systems handle resource
allocation and it fixes a bug where dense and bwx memory allocations were
not handled properly.

b39746576c syslogd gets kernel log messages only once every 30 seconds or
at the top of the minute, whichever comes first.  It seems
logtimeout() is only called once after the kernel log is opened
and then never again after that.  So I guess syslogd only gets
kernel log messages by virtue of syncer(4)'s flushes ...?
