spin locks that are not in the static order list. It is not safe to call
printf while holding the witness spin mutex since the console drivers that
back printf may need to use their own spin locks which would try to talk
to witness when they were locked. Given this, it is possible for one
CPU to lock a console driver lock (such as sio) which then tries to lock
the witness lock while another CPU is doing the printf while holding the
witness lock. Fix this by moving the printf outside of the witness lock.
All other printf's in witness are already correct.

similar the the Solaris implementation. Repackage the krb5 GSS mechanism
as a plugin library for the new implementation. This also includes a
comprehensive set of manpages for the GSS-API functions with text mostly
taken from the RFC.

Also return early if all pfil_* sysctls are turned off, the user obviously does

with FAST_IPSEC rather than the KAME IPSEC stack.
Note that the output of "netstat -s -p ipsec" differs depending on which
stack is compiled into the kernel since they each keep different stats.
This delta also adds the "esp", "ah", and "ipcomp" protocol stats, which
are also available when the kernel is compiled with the FAST_IPSEC stack
(e.g. "netstat -s -p esp").

perform varying number of small IPC operations. It runs using a single
process and one thread, a single process and two threads, and using
multiple processes. Critical to its performance measure are the cost and
frequency of context switches, locking overhead, and threading
performance. The benchmark generates .csv output appropriate for reading
into a spreadsheet to generate summary statistics and perform statistical
tests easily.
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.
