b7fa166b60 Add -e to set arbitrary kernel environment variables.
Nextboot(8) can now set any combination of kernel name (-k), kernel
options (-o), and environment strings (-e).  As a result of this change
-k also becomes optional.

87b633678b When a "mount -u" switches an NFS mount point from TCP to UDP,
any thread doing an I/O RPC with a transfer size greater than
NFS_UDPMAXDATA will be hung indefinitely, retrying the RPC.
After a discussion on freebsd-fs@, I decided to add a warning
message for this case, as suggested by Jeremy Chadwick.

a8122d16b5 jwd@ reported a problem via email to freebsd-fs@ on Aug 25, 2011
under the subject "F_RDLCK lock to FreeBSD NFS fails to R/O target file".
This occurred because the server side NLM always checked for VWRITE
access, irrespective of the type of lock request. This patch
replaces VOP_ACCESS(..VWRITE..) with one appropriate to
the lock operation. It allows unlock and lock cancellation
to be done without a check of VOP_ACCESS(), so that files
can't be left locked indefinitely after the file permissions
have been changed.

62f8a13a75 Add a DFS debugging mode which is useful when doing automated DFS
compliance testing.

In order to allow for radar pattern matching to occur, the DFS CAC/NOL
handling needs to be made configurable.  This commit introduces a new
sysctl, "net.wlan.dfs_debug", which controls which DFS debug mode
net80211 is in.

* 0 = default, CSA/NOL handling as per normal.
* 1 = announce a CSA, but don't add the channel to the non-occupy list
  (NOL.)
* 2 = disable both CSA and NOL - only print that a radar event occured.

This code is not compiled/enabled by default as it breaks regulatory
handling.  A user must enable IEEE80211_DFS_DEBUG in their kernel
configuration file for this option to become available.

7f925de11a Radar API related fixes.
* For legacy NICs, the combined RSSI should be used.
  For earlier AR5416 NICs, use control chain 0 RSSI rather than combined
  RSSI.
  For AR5416 > version 2.1, use the combined RSSI again.

* Add in a missing AR5212 HAL method (get11nextbusy) which may be called
  by radar code.

This serves no functional change for what's currently in FreeBSD.

2bd3e4c2c2 Refine the implementation of POSIX_FADV_NOREUSE for the read(2) case such
that instead of using direct I/O it allows read-ahead similar to
POSIX_FADV_NORMAL, but invokes VOP_ADVISE(POSIX_FADV_DONTNEED) after the
read(2) has completed to purge just-read data.  The write(2) path continues
to use direct I/O for POSIX_FADV_NOREUSE for now.  Note that NOREUSE works
optimally if an application reads and writes full fs blocks.

96459db58f As it turns out r227960 may still be insufficient with PREEMPTION
so try harder to get the CDMA sync interrupt delivered and also in
a more efficient way:
- wrap the whole process of sending and receiving the CDMA sync
  interrupt in a critical section so we don't get preempted,
- send the CDMA sync interrupt to the CPU that is actually waiting
  for it to happen so we don't take a detour via another CPU,
- instead of waiting for up to 15 seconds for the interrupt to
  trigger try the whole process for up to 15 times using a one
  second timeout (the code was also changed to just ignore belated
  interrupts of a previous tries should they appear).

According to testing done by Peter Jeremy with the debugging also
added as part of this commit the first two changes apparently are
sufficient to now properly get the CDMA sync interrupts delivered
at the first try though.

3c0f8828f4 Fully disable interrupts while we fiddle with the FP context in the
VIS-based block copy/zero implementations. While with 4BSD it's
sufficient to just disable the tick interrupts, with ULE+PREEMPTION
it's otherwise also possible that these are preempted via IPIs.

06fc4a109d Two changes from my DFS work:
* Grab the net80211com lock when calling ieee80211_dfs_notify_radar().
* Use the tsf extend function to turn the 64 bit base TSF into a per-
  frame 64 bit TSF.  This will improve radiotap logging (which will
  now have a (more) correct per-frame TSF, rather then the single TSF64
  value read at the beginning of ath_rx_proc().
