Parse the contents of file before continuing with the current file.
includedir <dir>:
Parse the contents of every file in dir that ends in .conf before continuing

Any file or directory encountered while processing include or includedir

Add to GEOM RAID class module, supporting the DDF metadata format, as
defined by the SNIA Common RAID Disk Data Format Specification v2.0.
Supports multiple volumes per array and multiple partitions per disk.
Supports standard big-endian and Adaptec's little-endian byte ordering.
Supports all single-layer RAID levels. Dual-layer RAID levels except
RAID10 are not supported now because of GEOM RAID design limitations.
Some work is still to be done, but the present code already manages basic
interoperation with RAID BIOS of the Adaptec 1430SA SATA RAID controller.
Improve growfs(8) in a few ways; unfortunately, it's somewhat hard to untangle
them and commit separately.
1. Rewrite the way growfs(8) finds the device and mount point. This makes
it possible to use e.g. "growfs /mnt"; it's also used to display more
helpful messages.
2. Be more user-friendly, using descriptive messages, like this:
OK to grow filesystem on /dev/md0, mounted on /mnt, from 9.8GB to 20GB? [Yes/No]"
3. Allow to specify the size (-s option) just like with mdconfig(8), i.e. with
postfixes ("mdconfig -s 10g").
4. Reload read-only filesystem after growing.

Remove incorrect __restrict qualifier on several pointers
The typical case was:
static __inline int
convert_ccl(FILE *fp, char * __restrict p, [...])
{
[...]
if (p == SUPPRESS_PTR) {
[...]
} else {
[...]
}
[...]
}
This qualifier says that the pointer is the only one at that time
pointing to the resource.
Here, clang considers that "p" will never match "SUPPRESS_PTR" and
optimize the if{} block out. This leads to segfaults in programs calling
vfscanf(3) and vfwscanf(3) with just the format string (no arguments
following it).
The following softwares were reported to abort with segmentation fault
and this patch fixes it:
o cmake
o smartd
o devel/ORBit2

Print out a warning message if a `lpc setstatus' is done when

Fix a bug in *wscanf's handling of non-wide %s, %c, and %[
conversions. Both the specification and the documentation say the
width is interpreted as the max number of wide characters to read, but
the implementation was interpreting it as the number of bytes to convert.
(See also r105317.)
This change has security implications for any applications that depend
on the buggy behavior, but the impact in practice is probably nil.
Any such application would already be buggy on other platforms that
get the semantics right. Also, these conversions are rarely used;
%ls, %lc, and %l[ are more appropriate.
Catch the user-error when no queue name was specified on an
lpc-command which supports '-msg' (e.g.: setstatus). Print
out a helpful error message instead hitting a seg-fault.

Previously, vfscanf()'s wide character processing functions were
reading wide characters manually. With this change, they now use
fgetwc(). To make this work, we use an internal version of fgetwc()
with a few extensions: it takes an mbstate * because non-wide streams
don't have a built-in mbstate, and it indicates the number of bytes
read.
vfscanf() now resembles vfwscanf() more closely. Minor functional
improvements include working xlocale support in vfscanf(), setting the
stream error indicator on encoding errors, and proper handling of
shift-based encodings. (Actually, making shift-based encodings work
with non-wide streams is hopeless, but the implementation now matches
the broken specification.)

After thinking about this a bit more, let's not keep statistics per-channel
in the HAL. That's very memory hungry (32k just for channel statistics)
which would be better served by keeping a summary in the ANI state.
Or, later, keep a survey history in net80211.
So:
* Migrate the ah_chansurvey array to be a single entry, for the current
channel.
* Change the ioctl interface and ANI code to just reference that.
* Clear the ah_chansurvey array during channel reset, both in the AR5212
and AR5416 reset path.
Move crypto stuff into a common Makefile. While here fix the
WITHOUT_OPENSSL build by using the wpa's internal crypto support if
openssl is not available, this allows us to unconditionally enable
EAP support.

Extend the ANI code to implement basic channel survey support.
* Always call ar5416GetListenTime()
* Modify ar5416GetListenTime() to:
+ don't update the ANI state if there isn't any ANI state;
+ don't update the channel survey state if there's no active
channel - just to be paranoid
+ copy the channel survey results into the current sample slot
based on the current channel; then increment the sample counter
and sample history counter.
* Modify ar5416GetMIBCyclesPct() to simply return a HAL_SURVEY_SAMPLE,
rather than a set of percentages. The ANI code wasn't using the
percentages anyway.
TODO:
* Create a new function which fetches the survey results periodically
* .. then modify the ANI code to use the pre-fetched values rather than
fetching them again
* Roll the 11n ext busy function from ar5416_misc.c to update all the

Add an AR5416 PCU DMA stop method, as a check for the AR9130 is needed.
The reference driver has a 3ms delay for the AR9130 but I'm not as yet
sure why. From what I can gather, it's likely waiting for some FIFO
flush to occur.
At some point in the future it may be worthwhile adding a WMAC
FIFO flush here, but that'd require some side-call through to the SoC
DDR flush routines.

Implement the D "cpu" variable, which returns curcpu. I have chosen not

cpu as an inline that took a value out of curthread. At certain points in

particukar, just before the thread gets descheduled) so instead I have

For Yukon II controllers that implement optional temperature sensor
and voltage sensor, TWSI is used to get sensor data. msk(4) does
not monitor these sensors and interrupt for TWSI completion is
disabled by default.
However, due to unknown reason, the TWSI completion interrupt fires
and it resulted in interrupt storm. To fix it, acknowledges the
TWSI completion interrupt if driver see the event. Given that not
all Yukon II controllers show the issue it could be a silicon bug
which does not honor interrupt masking.
Probably the right way to address the issue is disabling automatic
TWSI cycle initiation against these sensors. It would be even
better to implement reading voltage/temperature from the NIC but it
requires access to National LM80 through TWSI and documentation to
do that is not available yet(probably will never happen).
