62f9fae610 If the user exists abruptly, tip's "tipout" child can hang around
forever. Since the lock file doesn't get cleaned up, this prevents
other users from accessing the target device.

ac8f990bde This patch implements O_DIRECT about 80% of the way. It takes a patchset
Tor created a while ago, removes the raw I/O piece (that has cache coherency
problems), and adds a buffer cache / VM freeing piece.

Essentially this patch causes O_DIRECT I/O to not be left in the cache, but
does not prevent it from going through the cache, hence the 80%.  For
the last 20% we need a method by which the I/O can be issued directly to
buffer supplied by the user process and bypass the buffer cache entirely,
but still maintain cache coherency.

I also have the code working under -stable but the changes made to sys/file.h
may not be MFCable, so an MFC is not on the table yet.

4d5a4ec15f Do what we should have done a long time ago:
o If the class is PCIC_BRIDGE, subclass is PCIS_BRIDGE_PCMCIA and
  programming interface is 0, assume that it is a generic PCMCIA PCI
  chip we can program.  I don't think there are any of these that
  we don't know about, but you never know.
o If the class is PCIC_BRIDGE, subclass is PCIS_BRIDGE_CARDBUS and
  programming interface is 0, assume that it is a YENTA cardbus bridge
  that we know how to cope with.  There are likely some cardbus bridges
  that haven't it made it in here yet.

99efcc2bb9 Move getb1 and putb1 from pcic_isa.c to pcic.c. Rename them to
pcic_{get,put}b_io.  There are some pci bridges (the CL-PD6729 and
maybe others) that do not have memory mapped registers, so we'll need
these in both places.  Declare them in pcicvar.h.

3614c6fcbb - 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().

60517fd1f7 - 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.

- 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.

134c58d3c0 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.
