b43: avoid packet losses in the dma worker code.
Following Rafal request, we verified that on "modern" CPUs using one

packet loss bug in the dma engine using only one worker.

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.

Bluetooth: Don't disable tasklets to call hdev->notify()
It's pointless, we aren't protecting anything since btusb_notify()
schedules a work to run, then all it operation happens without protection.
If protection is really needed here, we will fix it further.

iwlwifi: we can wake SW queues even when draining HW queues
In the very first implementation of HT, the driver was responsible
for the queueing: stopping and waking the queues while the HW queues
where being drained. In this implementation, we had to deal with the
case where we were draining the AGG queue because we wanted to tear
down the BA agreement.
In the normal flow (when we don't drain any HW queue), when packets
are reclaimed, we wake the SW queue in case the SW queue was stopped
which can happen when the HW queues are too full.
While draining a HW queue, we must make sure that we don't wake the
SW queue, since the whole point of the draining is to empty totally
the HW queue and not only get below a certain threshold.
This is why there is condition in the reclaim function:
if (NOT EMPTYING DELBA)
wake the SW queue is applicable
Since then, a lot has changed and mac80211 is now able to buffer
packets that are being sent to a packet list that will be spliced
after the driver has reported it has drained its HW queues.
Hence, there is no need for the for aforementioned if, and we can
safely wake up the queue even if we are draining HW queues.
Removing this if, also allows us to remove the wake_queue in
check_empty that was there in order to deal with a corner case
created by the if.

iwlwifi: don't count the tfds in HW queue any more
Since packets sent to an RA / TID in AGG are sent from a
separate HW Tx queue, we may get into a race:
the regular queue isn't empty while we already begin to
send packets from the AGG queue. This would result in sending
packets out of order.
In order to cope with this, mac80211 waits until the driver
reports that the legacy queue is drained before it can send
packets to the AGG queue. During that time, mac80211 buffers
packets for the driver. These packets will be sent in order
after the driver reports it is ready.
The way this was implemented in the driver is as follows:
We held a counter that monitors the number of packets for
an RA / TID in the HW queues. When this counter reached 0,
we knew that the HW queues were drained and we reported to
mac80211 that were ready to proceed.
This patch changes the implementation described above. We
now remember what is the wifi sequence number of the first
packet that will be sent in the AGG queue (lets' call it
ssn). When we reclaim the packet before ssn, we know that
the queue is drained, and we are ready to proceed.
This will allow us to move this logic in the upper layer and
eventually remove the tid_data from the shared area.

cfg80211: allow following country IE power for custom regdom cards
By definition WIPHY_FLAG_STRICT_REGULATORY was intended to allow the
wiphy to adjust itself to the country IE power information if the
card had no regulatory data but we had no way to tell cfg80211 that if
the card also had its own custom regulatory domain (these are typically
custom world regulatory domains) that we want to follow the country IE's
noted values for power for each channel. We add support for this and
document it.
This is not a critical fix but a performance optimization for cards
with custom regulatory domains that associate to an AP with sends
out country IEs with a higher EIRP than the one on the custom
regulatory domain. In practice the only driver affected right now
are the Atheros drivers as they are the only drivers using both
WIPHY_FLAG_STRICT_REGULATORY and WIPHY_FLAG_CUSTOM_REGULATORY --
used on cards that have an Atheros world regulatory domain. Cards
that have been programmed to follow a country specifically will not
follow the country IE power. So although not a stable fix distributions
