the sign bit doesn't cause an overflow. The overflow manifests itself
as a sorting index wrap around in the middle of the sorted array,
which is not a problem for the LRO code, but might be a problem for
the logic inside qsort().

This is a prelude to intr-ng support for MIPS boards that need it -
notably the CI20 port from kan@ that's upcoming, but also work that
Stanislav is doing for the Mediatek platforms.
This is the initial platform dependent bits in include/intr.h, some
#defines for the nexus code for the intrng initialisation/runtime
bits, some changed naming (which I'll fix later to be the same, much
like what I did for ARM intr-ng) in exception.S, and the first cut
at a PIC.
Stanislav and I refactored out the common code for intrng support,
so the mips intrng definitions are quite small (sys/mips/include/intr.h.)
This is all work done by kan@, which stanislav has been cherry picking
into common code for his mediatek chipset work.
Tested:
* Carambola2 - no regressions (not intr-ng though!)

This is ongoing work from Damjan Jovanovic to improve ext4 read support
with sparse files:
Keep track of the first and last block in each extent as it descends down
the extent tree, thus being able to work out that some blocks are sparse
earlier. This solves an issue on r293680.
In ext4_bmapext() start supporting the runb parameter, which appears to be
the number of adjacent blocks prior to the block being converted in the
same way that runp is the number of blocks after, speding up random access
to mmaped files.

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

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.
