Replace the hw.ntb.enable_writecombine tunable with
hw.ntb.default_mw_pat. It can be set with several specific numerical
values to select a caching type. Any bogus value is treated as
Uncacheable (UC).
The ntb_mw_set_wc() KPI has removed the restriction that the selected
mode must be one of UC, WC, or WB.

When a user defines "jail_list" in rc.conf the jails are started in the
order defined. Currently the jails are not are stopped in reverse order
which may break dependencies between jails/services and prevent a clean
shutdown. The new parameter "jail_reverse_stop" will shutdown jails in
"jail_list" in reverse order when set to "YES".
Please note that this does not affect manual invocation of the jail rc
script. If a user runs the command
# service jail stop jail1 jail2 jail3
the jails will be stopped in exactly the order specified regardless of
jail_reverse_stop being defined in rc.conf.

The services db is created as a temporary file that is moved over the
existing file after completion. Thus there is no need to immediately
flush all created db records to the temporary file.
This speeds up creation of the services db by a factor of 500 on my
ZFS based /var/db filesytem (from 110 seconds to 0.235 seconds).

made writeable by the root user. Userspace audio daemons can add or
update an entry in /dev/sndstat by doing a single system write call to
any /dev/sndstat file descriptor handle. When the audio daemon closes the
file handle or is killed the entry disappears.
While at it, cleanup the sound status code a bit:
- keep the device list sorted to avoid sorting the list every time a
/dev/sndstat read request is made.
- factor out locking into a pair of locking macros.
- use the sound status lock to protect all per file handle states,
when generating the output for /dev/sndstat and when removing or
adding sound status devices. This way sndstat_acquire() and
sndstat_release() become superfluous and can be removed.

Currently, there is no easy way to know in advance how many entries a list parsed by
ofw_bus_parse_xref_list_alloc() in sys/dev/ofw/ofw_bus_subr.c has.
This patch:
* teaches the existing function about handling idx == -1 and returning how big
the set is; then renames it as _internal;
* create a new function that asserts idx != -1, so the old API is maintained;
* add a new function that returns just the list length.

Kernel threads (and processes) are supposed to call kthread_exit() (or
kproc_exit()) to terminate. However, the kernel includes a fallback in
fork_exit() to force a kthread exit if a kernel thread's "main" routine
returns. This fallback was added back when the kernel only had processes
and was not updated to call kthread_exit() instead of kproc_exit() when
threads were added to the kernel.
This mistake was particular exciting when the errant thread belonged to
proc0. Due to the missing P_KTHREAD flag the fallback did not kick in
and instead tried to return to userland via whatever garbage was in the
trapframe. With P_KTHREAD set it tried to terminate proc0 resulting in
other amusements.
