e3c5a44915 Work around an Intel 21143 chip bug.
Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick()
routine.  dc_tick() is called regularly to detect link up and link down
status, especially when autonegotiating.

The expectation was that mii_tick() (which is still called from dc_tick())
would update status information automatically in all cases where it would
be sensible to do so.

Unfortunately, with authentic 21143 chips this is not the case, and
the driver never successfully autonegotiates.  This is because (despite
what it says in the 21143 manual) the chip always claims that link is not
present while the autonegotiation enable bit is set.  Autonegotation takes
place and succeeds, but the driver tests the link bits before it switches
off the autonegotiation enable bit, and success is not recognised.

The simplest solution is to call dcphy_status() more often for MII_TICK
calls by dropping out of the switch statement instead of exiting when
we are autonegotiating and link appears to not be present.  When
autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx
state and turn off the autonegotiation enable bit.  The next call to
dcphy_status() will notice that link is present, and the dc driver code
will be notified.

Macronix chips also use this code, but implement link detection as
described in the manual, and hence don't need this patch.  However, tests
on a Macronix 98715AEC-C show that it does not adversely affect them.

This could be done better but is the minimal effective change, and most
closely mimics what was happening prior to rev 1.56 of if_dc.c.  (Actually
I also deleted a small amount of unnecessary code while I was in the area.)

6139043b1f o Call vm_map_growstack() from vm_fault() if vm_map_lookup() has failed
due to conditions that suggest the possible need for stack growth.
   This has two beneficial effects: (1) we can
   now remove calls to vm_map_growstack() from the MD trap handlers and (2)
   simple page faults are faster because we no longer unnecessarily perform
   vm_map_growstack() on every page fault.
 o Remove vm_map_growstack() from the i386's trap_pfault().
 o Remove the acquisition and release of Giant from i386's trap_pfault().
   (vm_fault() still acquires it.)

d786139c76 Rework the kernel environment subsystem. We now convert the static
environment needed at boot time to a dynamic subsystem when VM is
up.  The dynamic kernel environment is protected by an sx lock.

This adds some new functions to manipulate the kernel environment :
freeenv(), setenv(), unsetenv() and testenv().  freeenv() has to be
called after every getenv() when you have finished using the string.
testenv() only tests if an environment variable is present, and
doesn't require a freeenv() call. setenv() and unsetenv() are self
explanatory.

The kenv(2) syscall exports these new functionalities to userland,
mainly for kenv(1).

334f706177 Do not free the vmspace until p->p_vmspace is set to null. Otherwise
statclock can access it in the tail end of statclock_process() at an
unfortunate time.  This bit me several times on an SMP alpha (UP2000)
and the problem went away with this change.  I'm not sure why it doesn't
break x86 as well.  Maybe it's because the clocks are much faster
on alpha (HZ=1024 by default).

200e654a4a I am not sure why ## was used in this macro, as w/o the string concatenation
the tokens are legal ANSI-C.  Maybe to enable 'op' to be a macro itself?
Anyway, with the ## concatenation Gcc 3.1's integrated `cpp' treats "=op("
as a single token vs. the three tokens it is.

df99ca52f1 The recent NFS forced unmount improvements introduced a side-effect
where some client operations might be unexpectedly cancelled during
an unsuccessful non-forced unmount attempt. This causes problems
for amd(8), because it periodically attempts a non-forced unmount
to check if the filesystem is still in use.

Fix this by adding a new mountpoint flag MNTK_UNMOUNTF that is set
only during the operation of a forced unmount. Use this instead of
MNTK_UNMOUNT to trigger the cancellation of hung NFS operations.

Also correct a problem where dounmount() might inadvertently clear
the MNTK_UNMOUNT flag.
