This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code. It is based on commit bad6919469,
which fixes the same problem in b43.

Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:
o Frans Pop RIP 2010 [0]
- Frans Pop <elendil@planet.nl>
- Frans Pop <fjp@debian.org>
o Nokia RIP February, 11, 2011 [1], [2]
- ext-yuri.ershov@nokia.com
- kalle.valo@nokia.com
Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.
As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.
The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

Define special location values for RX NFC that request the driver to
select the actual rule location. This allows for implementation on
devices that use hash-based filter lookup, whereas currently the API is
more suited to devices with TCAM lookup or linear search.
In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy
the structure back to user-space after insertion so that the actual
location is returned.

This reverts commit 93b2ec0128.
The call to "schedule_work()" in rtc_initialize_alarm() happens too
early, and can cause oopses at bootup
Neil Brown explains why we do it:
"If you set an alarm in the future, then shutdown and boot again after
that time, then you will end up with a timer_queue node which is in
the past.
When this happens the queue gets stuck. That entry-in-the-past won't
get removed until and interrupt happens and an interrupt won't happen
because the RTC only triggers an interrupt when the alarm is "now".
So you'll find that e.g. "hwclock" will always tell you that
'select' timed out.
So we force the interrupt work to happen at the start just in case."
and has a patch that convert it to do things in-process rather than with
the worker thread, but right now it's too late to play around with this,
so we just revert the patch that caused problems for now.

It appears about all functions in arch/x86/lib/atomic64_cx8_32.S
are wrong in case cmpxchg8b must be restarted, because
LOCK_PREFIX macro defines a label "1" clashing with other local
labels :
1:
some_instructions
LOCK_PREFIX
cmpxchg8b (%ebp)
jne 1b / jumps to beginning of LOCK_PREFIX !
A possible fix is to use a magic label "672" in LOCK_PREFIX asm
definition, similar to the "671" one we defined in
LOCK_PREFIX_HERE.

Just like the per-CPU ones they had several
problems/shortcomings:
Only the first memory operand was mentioned in the asm()
operands, and the 2x64-bit version didn't have a memory clobber
while the 2x32-bit one did. The former allowed the compiler to
not recognize the need to re-load the data in case it had it
cached in some register, while the latter was overly
destructive.
The types of the local copies of the old and new values were
incorrect (the types of the pointed-to variables should be used
here, to make sure the respective old/new variable types are
compatible).
The __dummy/__junk variables were pointless, given that local
copies of the inputs already existed (and can hence be used for
discarded outputs).
The 32-bit variant of cmpxchg_double_local() referenced
cmpxchg16b_local().
At once also:
- change the return value type to what it really is: 'bool'
- unify 32- and 64-bit variants
- abstract out the common part of the 'normal' and 'local' variants
