sysclock_getsnapshot() function allows the caller to obtain a snapshot of all
the system clock and timecounter state required to create time stamps at a later
point. The sysclock_snap2bintime() function converts a previously obtained
snapshot into a bintime time stamp according to the specified flags e.g. which
system clock, uptime vs absolute time, etc.
These KPIs enable useful functionality, including direct comparison of the
feedback and feed-forward system clocks and generation of multiple time stamps
with different formats from a single timecounter read.

MS_SYNC flag. The system must guarantee that all writes are finished
before syscalls returned. Schedule the writes in async mode, which is
much faster and allows the clustering to occur. Wait for writes using
VOP_FSYNC(), since we are syncing the whole file mapping.
Potentially, the restriction to only apply the optimization can be
relaxed by not requiring that the mapping cover whole file, as it is
done by other OSes.

The reference driver directly enables/disables the LED state as required,
rather than nailing it up like it currently is. That'll have to come
later by adding some further HAL methods.

* Bring the AR5416 GPIO mux mask code in line with the code from the
HAL.
* Add HAL_DEBUG_GPIO debugging statements, to track what's going on.
* Add Kiwi GPIO specific changes for reading values back.
Obtained from: Atheros
* As a preparation for AR9287 GPIO support, add in the AR9287 GPIO mask.
* Fix the association mask values; these are post-shift values but were
being shifted in twice. This resulted in some garbage being written
in the wrong place and the link LED (at least on my d-link AR5416
NIC) giving totally incorrect blink patterns.
Some users were reporting concurrent resets _were_ occuring - ie,
either two ath_reset()s ran at the same time (likely one on each CPU)
or ath_reset() versus ath_chan_change().
Instead, this now tries to grab the serialisation semaphore and will
pause() for a while if it fails. It will always eventually succeed though
and will log an error if it hits the recursion situation.
All of this stuff needs to die a horrible death at some point and be
replaced with a properly serialising method of programming this stuff
(eg using the net80211 taskqueue for all of this stuff.) The trouble
is figuring out how to handle the concurrent ioctl() based things without
introducing more LORs (which is another reason why I haven't just wrapped
all of this stuff in large, long-lived locks, a-la what Linux can get
away with.)

This doesn't fix compilation w/out AH_SUPPORT_AR5416 as all of the software

going on with the occasional garbage rs_antenna field reported by AR9285
users.
I've discovered that the 11n NICs only fill out the entire RX status
descriptor on the final descriptor in an aggregate. Some of the fields
(notably RSSI) are complete nonsense for A-MPDU subframes. This may
be another example of this.
The driver doesn't currently toss out statistics for non-final aggregate
frames. It's likely that this should be done.
If any users hit this particular debugging message they should report it
immediately to freebsd-wireless@freebsd.org - please ensure you have
ATH_DEBUG enabled so it prints out the full receive descriptor.

jhb@ spotted that nfscl_getstateid() might modify credentials when
called from nfsrpc_read() for the case where p != NULL, whereas
nfsrpc_read() only did a crdup() to get new credentials for p == NULL.
This bug was introduced by r195510, since pre-r195510 nfscl_getstateid()
only modified credentials for the p == NULL case. This patch modifies
nfsrpc_read()/nfsrpc_write() so that they do crdup() for the p != NULL case.
It is conceivable that this bug caused the crash reported by glebius@, but
that will not be determined for some time, since the crash occurred after
about 1month of operation.
