rev. 1.438 of sys/kern/vfs_syscalls.c,
rev. 1.77 of sys/sys/filedesc.h:
Mark the filedescriptor table entries with VOP_OPEN being performed for them
as UF_OPENING. Disable closing of that entries. This should fix the crashes
caused by devfs_open() (and fifo_open()) dereferencing struct file * by
index, while the filedescriptor is closed by parallel thread.

* Fix possible integer overflow during speed calibration. Delay final
initialization (pcm_setstatus) after calibration finished.

* Fix (or rather workaround) Intel 440MX Errata #36
- http://www.intel.com/design/chipsets/specupdt/245051.htm
AC97 Soft Audio and Soft Modem Master Abort Errata
Issue:
Use of either soft audio or soft modem on an Intel® 82443MX PCISet
based platform running a 100 MHz Processor System Bus and an AC97 codec
may result in failures. The system continues to function normally while
the AC97 hardware may not resume and may require a cold-boot to
recover. As a result of the failure, the Master Abort Status bit will
be set in the audio or modem function PCI header space.
Workaround:
Force uncacheable DMA on both BDL and pcm buffers.

- add some performance improvements for small packet workloads
- Double the number of descriptors that a single call to send can use
- Quadruple the number of descriptors that can be reclaimed per pass
- only run reclaim twice per second
- increase coalesce timer from 3.5us to 5us
- set OACTIVE so interface doesn't stall when the ring fills

: Add a pfsync_syncpeer option to /etc/defaults/rc.conf and rc.conf(5),
: which can be used to turn off multicast pfsync support, and enable
: the transmission of directed PFSYNC (IP protocol: 240) packets to
: a specific "sync peer" host.

- Disabled responding to NI queries from a global address by default as
specified in RFC4620. A new flag for icmp6_nodeinfo was added to enable the
feature.
- Also cleaned up the code so that the semantics of the icmp6_nodeinfo
flags is clearer (i.e., defined specific macro names instead of using
hard-coded values).

a 64-bit process exec'd by a 32-bit process doesn't end up with 32-bit
limits.
This doesn't break the ABI as neither of the 32-bit ABIs (COMPAT_LINUX32
and COMPAT_IA32) are buildable as modules on 6.x/amd64 and none of the
other ABIs use this hook.
* Add missing '${BASEDIR}/'s, thereby fixing problems when the "-b basedir"
option is used.
* Don't add new kernel modules into a non-existent kernel directory.
* Remove files before the directory which contains them.
