- Release the pci_link acpi serial lock if a link device has no actual
links.
- Don't panic if a _PRT entry references an invalid link on a link device
unless we actually try to route an interrupt using that _PRT entry.
In ng_netflow_disconnect() check whether we are working with "iface"
or with "out" hook, and clear the right pointer.

When in rev. 1.47 cardbus_alloc_resources() function was moved from
cardbus_cis.c to this file, some code was not merged and thus resource
list entries were invalid. They didn't have a resources attached to
them.
However, the problem was masked for some time later, because newer
resources list entries were added to the head of the list, and
resource_list_find() always returned the first matching resource list
entry. Usually the underlying driver allocated a valid resource and
added it to the head of the list, and invalid one wasn't used.
In rev. 1.174 of subr_bus.c the sorting of resource list entries was
reversed demasking the problem in cardbus_alloc_resources().
This commit fixes the problem returning back some code from
cardbus_cis.c, pre-1.49 revisions.

To preserve kernel modules ABI, unlike the version commited into the trunk,
which adds new flag field into Brandinfo structure for this purpose, this
one checks if brand field of Brandinfo matches ELFOSABI_LINUX.

Avoid kernel panic when attaching a process which
may not be stopped by debugger, e.g process is dumping core.
Call fill_kinfo_proc_only() instead of fill_kinfo_proc()
before calling fill_kinfo_thread(), because fill_kinfo_proc()
calls both fill_kinfo_proc_only() and fill_kinfo_thread().
This is a minor optimization and there should be no change
in functionality.
Leading whitespace cleanup.

Apply the same fix to a potential race in the ISDOTDOT code in
cd9660_lookup() that was used to fix an actual race in ufs_lookup.c:1.78.
This is not currently a hazard, but the bug would be activated by
marking cd9660 as MPSAFE.

Original commit messages:
Log:
Track all lock relationships instead of pruning direct relationships
if an indirect relationship exists (keep both A->B->C and A->C).
This allows witness_checkorder() to use isitmychild() instead of
the much more expensive isitmydescendant() to check for valid lock
ordering.
Don't do an expensive tree walk to update the w_level values when
the tree is updated. Only update the w_level values when using the
debugger to display the tree.
Nuke the experimental "witness_watch > 1" mode that only compared
w_level for the two locks. This information is no longer maintained
at run time, and the use of isitmychild() in witness_checkorder
should bring performance close enough to the acceptable level that
this hack is not needed.
Report witness data structure allocation statistics under the
debug.witness sysctl.

In watchdog_config enable the software watchdog iff the WD_ACTIVE flag
is set. When watchdogd(1) is terminated intentionally it clears the

most of the sysctl's (those which would introduce a new interface).
The spdif_enabled sysctl is still there (or more correctly: added
to another driver).
A rough overview what's there now:
- new driver for ATI chips (snd_atiixp)
- support for some Intel HDA chips in AC97 mode (no real HDA
support!), this doesn't work with every mainboard and is
subject to the wiring on the mainboard (no servicable parts
inside)
- MPSAFE and fixes for snd_als4000(4), snd_es137x(4),
snd_via82c686(4), snd_via8233(4) and snd_ich(4)
- 24bit and 32bit sound format support
- feeder infrastructure (format, rate) has been reworked, new
feeder (volume) has been introduced
- lots of LOR and panic issues fixed
- and a lot of small or not so small fixes I may have forgotten...
As noted in UPDATING: you may want to recompile mplayer (after booting
into the new world) to get all new features.

Move PFSTATE_EXPIRING from sync_flags to a new local_flags. sync_flags
has special handling when zero. This caused no PFSYNC_ACT_DEL message and
thus disfunction of pfflowd and state synchronisation in general.
