but never accept'ed, so they must be destroyed. Originally, unp_drop()
detected this situation by checking if so->so_head is non-NULL.
However, since revision 1.54 of uipc_socket.c (Feb 1999), so->so_head
is set to NULL before calling soabort(), so any unix-domain sockets
waiting to be accept'ed are leaked if the server socket is closed.
Resolve this by moving the socket destruction code into uipc_abort()
itself, and making it unconditional (the other caller of unp_drop()
never needs the socket to be destroyed). Use unp_detach() to avoid
the original code duplication when destroying the socket.

latch the acpi timer, resulting in weird deltas. The problem is severe
enough to adversely effect the timecounter code.
Default to the 'safe' version of the get-timecount function. The probe
will override it if a known-good chipset is found. This is temporary
until a more complete solution is found.

our feet when we look inside timecounter structures.
Make the "sync_other" code more robust by never overwriting the
tc_next field.
Add counters for the bin[up]time functions.
Call tc_windup() in tc_init() and switch_timecounter() to make sure
we all the fields set right.
Most of the contents are commented out as they are as-yet untested.
However, I wanted the contents to match our other arches, so that when
people make changes to {i386,alpha,ia64}, they will also make the same
changes here.

I am committing this here rather than in gcc/config/freebsd.h because the
profiled libgcc only exists with the native system compiler. It is not
created by a stock FSF build and we will never be able to get these bits
committed to the FSF CVS repo. Thus this is very much a FreeBSD "native"
issue.
AIOGCAP ioctl reports software-emulated formats. It defaults to on. People
who use performance-sensitive audio software and do not want it to pick a
software-emulated audio format instead of one supported by their hardware
should turn it off.
This unbreaks isdnphone(1) on systems with PCM-only sound cards.

pmap_qenter and pmap_qremove in preference to pmap_kenter/pmap_kremove.
The former maps in multiple pages at a time, and so can do a ranged
flush. Don't assume that pmap_kenter and pmap_kremove will flush the tlb,
even though they still do. It will not once the MI code is updated to use
pmap_qenter and pmap_qremove.
will be used to reduce the number of tlb shootdown ipis in an smp system
by sending one ipi for a whole range of pages, instead of one per page.
Munge the context demap operations slightly to support demapping a non-primary
context.
