felt that if something better comes along sooner, it can be used to
replace this code.
Delayed by: BSDcon and subsequent disk crash.
can clear the pointer to mutex, not the thread doing mutex
handoff. Because _mutex_lock_backout does not hold scheduler
lock while testing THR_FLAGS_IN_SYNCQ and then reading mutex
pointer, it is possible mutex owner begin to unlock and
handoff the mutex to the current thread, and mutex pointer
will be cleared to NULL before current thread reading it, so
current thread will end up with deferencing a NULL pointer,
Fix the race by making mutex waiters to clear their mutex pointers.
While I am here, also save inherited priority in mutex for
PTHREAD_PRIO_INERIT mutex in mutex_trylock_common just like what
we did in mutex_lock_common.
and use it in src/etc/sendmail/Makefile in case the user wants to use
a different path to the sendmail m4 sources (e.g., sendmail port users).

Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers. With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.
Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

order to use "unmanaged" pages in the kmem object, vm_map_delete() must
unconditionally perform pmap_remove(). Otherwise, sparc64 has problems.

32 bit binary stuff. 32 bit binaries do not like it much when the kernel
tries hard to put things above the 8GB mark.
I have a work-in-progress to fix this properly, but I didn't want to burn
anybody with this yet.
"will trim at" message printed when the user requests '-v'. The
previous code would often print the wrong time, such as:
On Sept 22, run: newsyslog -nv /var/log/wtmp
And see: will trim at Mon Sep 1 05:00:00 2003
correct msg: will trim at Wed Oct 1 05:00:00 2003

initialize a TSC timecounter until we know if it is broke or not.
XXX I think there is a bug in the i386 code here. init_TSC_tc() comes
after:
if (statclock_disable)
return;
ie: if you turn off the statclock interrupt, you dont get the TSC either.
