To be able to use printf extensions we need to turn off gcc format checking.
Following the convention of NO_WERROR and NO_WCAST_ALIGN add NO_WFORMAT,
which, when defined in Makefile, turns off compile-time format checking
(by adding -Wno-format), but still allows to use high WARNS level.

Add some tests for cexp() and cexpf(). (I need to clean up all of
these tests some day, but in the mean time, they're a useful sanity
check for future changes.)
Allow to compress on-the-wire data using two algorithms:
- HOLE - it simply turns all-zero blocks into few bytes header;
it is extremely fast, so it is turned on by default;
it is mostly intended to speed up initial synchronization
where we expect many zeros;
- LZF - very fast algorithm by Marc Alexander Lehmann, which shows
very decent compression ratio and has BSD license.
The execution of the shebang script requires putting interpreter path,
possible option and script path in the place of argv[0] supplied to
execve(2). It is possible and valid for the substitution to be shorter
then the argv[0].
Make this makefile a little more make-like (e.g. build only things that
need to be rebuilt) and add an FTP-area target. Next will be docs and
memstick builds.
Fix various issues in how %#T is handled:
- If precision is 0, don't print period followed by no digits.
- If precision is 0 stop printing units as soon as possible
(eg. if we have three years and five days and precision is 0
print only 3y5d).
- If precision is not 0, print all units (eg. 3y0d0h0m0s.00).

- With the addition of TLS support binutils started to make the addend
values for resolved symbols relative to relocbase instead of sections
so detect this case and handle as appropriate, which allows using
kernel modules linked with affected versions of binutils. Actually I
think this is a bug in binutils but given that apparently nobody
complained for nearly six years and powerpc has basically the same

Add an EEPROM op that extracts out the power table offset.
It defaults to -5 dBm for eeproms earlier than v21.
This apparently only applies to Merlin (AR9280) or later,

All the code in ath9k which checks the power table offset
and takes it into account first ensures the chip is

Change HALDEBUG() to be a macro that conditionally calls the debug output routine.
The earlier way of doing debugging would evaluate the function parameters
before calling the HALDEBUG. In the case of detailed register debugging
would mean a -lot- of unneeded register IO and other stuff was going on.
This method evaluates the ath_hal_debug variable before the function
parameters are evaluated, drastically reducing the amount of overhead
enabling HAL debugging during compilation.

Partially reworked r219042.
The reason for this is a bug at ktrops() where process dereferenced
without having a lock. This might cause a panic if ktrace was runned
with -p flag and the specified process exited between the dropping
a lock and writing sv_flags.
Since it is impossible to acquire sx lock while holding mtx switch
to use asynchronous enqueuerequest() instead of writerequest().
Rename ktr_getrequest_ne() to more understandable name [1].
Add two new system calls, setloginclass(2) and getloginclass(2). This makes
it possible for the kernel to track login class the process is assigned to,
which is required for RCTL. This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

The sample rate module currently does the slightly wrong thing when
determining whether to use MRR or not.
It uses the 11g protection mode when calculating 11n related stuff, rather
than checking the 11n protection mode.
Furthermore, the 11n chipsets can quite happily handle multi-rate retry w/
protection; the TX path and rate control modules need to be taught about
that.

o It changes ioctl to unsigned from uint8_t.

Disable trying to do HT/40 and short-GI TX.
These flags are just plain wrong - they're the node flags from negotiation,
not the configured flags. I'll jump in later on and figure out exactly
what should be done to properly set these two flags when in both STA mode
(ie, what the AP says is possible and what's configured) and AP mode
(ie, where the AP has a configuration, but then negotiates what's possible
with each node, so per-node configuration can and will differ.)
This allows the 11n 2.4ghz/ht20 mode to associate (but perform poorly still)
and exchange MCS rates with atheros reference APs and a Cisco/Linksys
E3000 AP.

Make a change to the implementation of the direct map to improve performance
on processors that support 1 GB pages. Specifically, if the end of physical
memory is not aligned to a 1 GB page boundary, then map the residual
physical memory with multiple 2 MB page mappings rather than a single 1 GB
page mapping. When a 1 GB page mapping is used for this residual memory,
access to the memory is slower than when multiple 2 MB page mappings are
used. (I suspect that the reason for this slowdown is that the TLB is
actually being loaded with 4 KB page mappings for the residual memory.)
