5c5c7982be Use the external clock input for our PLL.
This may not be a generally valid configuration, but neither is relying
on the PCI clock to be stable.

The only currently known and supported hardware is the VPN14x1 from
Soekris, and since it has external clock, we fail safe(r) by using
it.

Unfortunately there is no way to probe this reliably.

3d1d5bc3c3 Rearrange some of the GEOM debugging tools to be more structured.
Retire g_sanity() and corresponding debugflag (0x8)

  Retire g_{stall,release}_events().

  Under #ifdef DIAGNOSTIC:

    Make g_valid_obj() an official function and have it return an an
    non-zero integer which indicates the kind of object when found.

    Implement G_VALID_{CLASS,GEOM,CONSUMER,PROVIDER}() macros based
    on g_valid_obj().

    Sprinkle calls to these macros liberally over the infrastructure.

    Always check that we do not free a live object.

a24cc63af9 Fix several issues related to the KeInitializeTimer() etc... API stuff
that I added recently:

- When a periodic timer fires, it's automatically re-armed. We must
  make sure to re-arm the timer _before_ invoking any caller-supplied
  defered procedure call: the DPC may choose to call KeCancelTimer(),
  and re-arming the timer after the DPC un-does the effect of the
  cancel.

- Fix similar issue with periodic timers in subr_ndis.c.

- When calling KeSetTimer() or KeSetTimerEx(), if the timer is
  already pending, untimeout() it first before timeout()ing
  it again.

- The old Atheros driver for the 5211 seems to use KeSetTimerEx()
  incorrectly, or at the very least in a very strange way that
  doesn't quite follow the Microsoft documentation. In one case,
  it calls KeSetTimerEx() with a duetime of 0 and a period of 5000.
  The Microsoft documentation says that negative duetime values
  are relative to the current time and positive values are absolute.
  But it doesn't say what's supposed to happen with positive values
  that less than the current time, i.e. absolute values that are
  in the past.

  Lacking any further information, I have decided that timers with
  positive duetimes that are in the past should fire right away (or
  in our case, after only 1 tick). This also takes care of the other
  strange usage in the Atheros driver, where the duetime is
  specified as 500000 and the period is 50. I think someone may
  have meant to use -500000 and misinterpreted the documentation.

- Also modified KeWaitForSingleObject() and KeWaitForMultipleObjects()
  to make the same duetime adjustment, since they have the same rules
  regarding timeout values.

- Cosmetic: change name of 'timeout' variable in KeWaitForSingleObject()
  and KeWaitForMultipleObjects() to 'duetime' to avoid senseless
  (though harmless) overlap with timeout() function name.

With these fixes, I can get the 5211 card to associate properly with
my adhoc net using driver AR5211.SYS version 2.4.1.6.

5d328ed44b - Make the acquisition of Giant in vm_fault_unwire() conditional on the
pmap.  For the kernel pmap, Giant is not required.  In general, for
   other pmaps, Giant is required by i386's pmap_pte() implementation.
   Specifically, the use of PMAP2/PADDR2 is synchronized by Giant.
   Note: In principle, updates to the kernel pmap's wired count could be
   lost without Giant.  However, in practice, we never use the kernel
   pmap's wired count.  This will be resolved when pmap locking appears.
 - With the above change, cpu_thread_clean() and uma_large_free() need
   not acquire Giant.  (The first case is simply the revival of
   i386/i386/vm_machdep.c's revision 1.226 by peter.)

fe5a02c927 Lock down IP-layer encapsulation library:
- Add encapmtx to protect ip_encap.c global variables (encapsulation
   list).
 - Unifdef #ifdef 0 pieces of encap_init() which was (and now really
   is) basically a no-op.
 - Lock encapmtx when walking encaptab, modifying it, comparing
   entries, etc.
 - Remove spl's.

Note that currently there's no facilite to make sure outstanding
use of encapsulation methods on a table entry have drained bfore
we allow a table entry to be removed.  As such, it's currently the
caller's responsibility to make sure that draining takes place.

module unload and cloan interface destroy, create a new utility
function disc_destroy(), which is callded on a softc after it
has been removed from the global softc list; the cloaner and

a69d88af52 Move a vref call outside of proc locks and Giant. By virtue of the fact
that we (p1) are currently running, we hold a reference on p_textvp which
means the vnode cannot go away.  p2 cannot run yet (and hence cannot exit)
so this should be safe to do at this point.  As a bonus, it removes a
block of under-Giant code that was there to support the vref.

fcffa790e9 Retire pmap_pinit2(). Alpha was the last platform that used it. However,
ever since alpha/alpha/pmap.c revision 1.81 introduced the list allpmaps,
there has been no reason for having this function on Alpha.  Briefly,
when pmap_growkernel() relied upon the list of all processes to find and
update the various pmaps to reflect a growth in the kernel's valid
address space, pmap_init2() served to avoid a race between pmap
initialization and pmap_growkernel().  Specifically, pmap_pinit2() was
responsible for initializing the kernel portions of the pmap and
pmap_pinit2() was called after the process structure contained a pointer
to the new pmap for use by pmap_growkernel().  Thus, an update to the
kernel's address space might be applied to the new pmap unnecessarily,
but an update would never be lost.
