167aee3895 Refactor Xen PV code to use new event timers subsystem. That uses one-shot
Xen timer and time counter to provide one-shot and periodic time events.

On my tests this reduces idle interruts rate down to about 30Hz, and accor-
ding to Xen VM Manager reduces host CPU load by three times comparing to
the previous periodic 100Hz clock. Also now, when needed, it is possible to
increase HZ rate without useless CPU burning during idle periods.

Now only ia64 and some ARMs left not migrated to the new event timers.

2f399d37ee Remove duplicate code - add a function which calculates the ratesArray[]
table which contains the per-rate target TX power.

This code is shared between the v14 eeprom board setup (AR5416, AR9160,
AR9280) and will also be used by the upcoming Kite (AR9287) support.

68b3f39d74 Some diversity changes relating to AR9285.
* grab the main, alt and selected LNA config
* add some optional / disabled logging code
* add a check to reject packets with an invalid main rssi too,
  in case the alt is the active receive chain and main is -ve.

Note: The software-controlled combined diversity code is still disabled.

3d08a76bbc Use a name instead of a magic number for kern_yield(9) when the priority
should not change.  Fetch the td_user_pri under the thread lock.  This
is probably not necessary but a magic number also seems preferable to
knowing the implementation details here.

This change should fix a long standing link establishment issue of

0daf62d9f5 - Commit work from libprocstat project. These patches add support for runtime
file and processes information retrieval from the running kernel via sysctl
  in the form of new library, libprocstat.  The library also supports KVM backend
  for analyzing memory crash dumps.  Both procstat(1) and fstat(1) utilities have
  been modified to take advantage of the library (as the bonus point the fstat(1)
  utility no longer need superuser privileges to operate), and the procstat(1)
  utility is now able to display information from memory dumps as well.

  The newly introduced fuser(1) utility also uses this library and able to operate
  via sysctl and kvm backends.

  The library is by no means complete (e.g. KVM backend is missing vnode name
  resolution routines, and there're no manpages for the library itself) so I
  plan to improve it further.  I'm commiting it so it will get wider exposure
  and review.

  We won't be able to MFC this work as it relies on changes in HEAD, which
  was introduced some time ago, that break kernel ABI.  OTOH we may be able
  to merge the library with KVM backend if we really need it there.

6b00c928cb Make the NF calibration logic (hopefully!) more resistive to noisy
environments.

In setups where NF calibration can take a while, don't load the CCA
and kick off a new NF calibration if the previous one hasn't yet
completed. This shouldn't happen unless the environment is noisy but
those exist (hi phk!).

Here, if the previous NF hasn't completed when ar5416LoadNf() is run
(which reads the NF), it skips updating the history buffer, loading
the NF CCA array and kicking off the next NF cal. It's hoped it'll
occur in the next long calibration interval.

85191ae6e8 Remove the initial NF completion check.
This is taking quite a while for some people in some situations
(eg AR5418 in phk's Abusive Radio Environment).

Instead, the rest of the calibration related code should
ensure that a NF calibration has occured before reading NF
values and kicking off another NF calibration.

The channel should also likely be marked as "noisy" (CWINT)
if the NF calibration takes too long.

12c5d1f2bf AR9285 (Kite) fixes.
* Correct some of the silicon revision checks to match what
  the Atheros HAL does. (See [1] below.)

* Move the PA cal and init cal method assignment to -after-
  the mac version/revision IDs are stored. The AR9285 init
  cal was never being called.

* Enable ANI.

Note Kite 1.0 and 1.1 were prototypes that shouldn't be seen
in the wild. Linux ath9k simply removed the prototype code from
their codebase. I'm going to leave it in there for now but
make it conditionally compilable in the future.

5a147ba6c9 Since r117657, bge(4) does not enable buffer manager for BCM5705 or
newer controllers.  However, all data sheet I have access has no
indication that buffer manager should not be touched on these
controllers.  It seems the buffer manager always runs on BCM5705 or
newer controllers. Some controller(e.g. BCM5719) needs other buffer
manager configuration so driver should enable buffer manager for
all controllers.  Both Linux and OpenBSD/NetBSD use the same
approach.
This change polls enable bit of block to know whether specified
block was really stopped as well as enabling buffer manager for all
controllers in driver initialization.
