pc_cpumask were changed to cpuset_t. This now calculates the cpumask based
on pc_cpuid itself as pc_cpumask is slated for being deorbited. Note that
this needs r221750 to be MFC'ed in order to compile.
This seems to work fine but after a few dozens of successful IPIs something
suddenly adds pc_cpuid to pc_other_cpus, causing the respective assertions
in mp_machdep.c to be triggered when the latter is used as the base for the
targets.
must not, otherwise we tell the CPU to IPI itself, which the sun4u CPUs don't
support. For reasons unknown so far MD and MI IPI use actually still triggers
that assertion though.
This now calculates pc_cpumask based on pc_cpuid itself as the former is
slated for being deorbited.
This branch now at least boots UP again. MP needs more things converted and
the existing conversion from cpumask_t to cpuset_t still has bugs.

* 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.

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.

when the user has indicated that the system has synchronized TSCs or it has
P-state invariant TSCs. For the former case, we may clear the tunable if it
fails the test to prevent accidental foot-shooting. For the latter case, we
may set it if it passes the test to notify the user that it may be usable.

Using the default RX fast diversity settings seems to help quite
a bit.
Whilst I'm here, change the prototype to return HAL_BOOL rather than int.
I'm not sure whether we should install teken as a library on any stock
FreeBSD installation, but I can imagine people want to tinker around
with it now and then. Create a /sys/teken/libteken, which holds a
Makefile to install a shared library version of the terminal emulator,
complete with a manpage.
Also add Makefiles for the demo/stress applications, to build it against
the shared library.
For now, the diversity settings are controlled by 'txantenna',
-not- rxantenna. This is because the earlier chipsets had
controllable TX diversity; the RX antenna setting twiddles
the default antenna register. I'll try sort that stuff out at
some point.
Call the antenna switch function from the board setup function
so scans, channel changes, mode changes, etc don't set the
diversity back to a default state too far from what's intended.
Things to todo:
* Squirrel away the last antenna diversity/combining parameters
and restore them during board setup if HAL_ANT_VARIABLE is
defined. That way scans, etc don't reset the diversity settings.
* Add some more public facing statistics, rather than what's
simply logged under HAL_DEBUG_DIVERSITY.
For now, the fixed antenna settings behave better than variable
settings for me. I have some further fiddling to do..

keep constant ISN growth rate, do the same directly inside tcp_new_isn(),
taking into account how much time (ticks) passed since the last call.
On my test systems this decreases idle interrupt rate from 140Hz to 70Hz.
Because we have no iconv in base, support for other charsets is not
possible.
Note that \u/\U are processed using the locale that was active when the
shell started. This is necessary to avoid behaviour that depends on the
parse/execute split (for example when placing braces around an entire
script). Therefore, UTF-8 encoding is implemented manually.
