Merge tag 'master-2014-09-08' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next

John W. Linville says:

====================
pull request: wireless-next 2014-09-08

Please pull this batch of updates intended for the 3.18 stream...

For the mac80211 bits, Johannes says:

"Not that much content this time. Some RCU cleanups, crypto
performance improvements, and various patches all over,
rather than listing them one might as well look into the
git log instead."

For the Bluetooth bits, Gustavo says:

"The changes consists of:

        - Coding style fixes to HCI drivers
        - Corrupted ack value fix for the H5 HCI driver
        - A couple of Enhanced L2CAP fixes
        - Conversion of SMP code to use common L2CAP channel API
        - Page scan optimizations when using the kernel-side whitelist
        - Various mac802154 and and ieee802154 6lowpan cleanups
        - One new Atheros USB ID"

For the iwlwifi bits, Emmanuel says:

"We have a new big thing coming up which is called Dynamic Queue
Allocation (or DQA).  This is a completely new way to work with the
Tx queues and it requires major refactoring.  This is being done by
Johannes and Avri.  Besides this, Johannes disables U-APSD by default
because of APs that would disable A-MPDU if the association supports
U-ASPD.  Luca contributed to the power area which he was cleaning
up on the way while working on CSA.  A few more random things here
and there."

For the Atheros bits, Kalle says:

"For ath6kl we had two small fixes and a new SDIO device id.

For ath10k the bigger changes are:

 * support for new firmware version 10.2 (Michal)

 * spectral scan support (Simon, Sven & Mathias)

 * export a firmware crash dump file (Ben & me)

 * cleaning up of pci.c (Michal)

 * print pci id in all messages, which causes most of the churn (Michal)"

Beyond that, we have the usual collection of various updates to ath9k,
b43, mwifiex, and wil6210, as well as a few other bits here and there.

Please let me know if there are problems!

/*
* This API allows the Host to access Target registers directly
* and relatively efficiently over PCIe.
* This allows the Host to avoid extra overhead associated with
* sending a message to firmware and waiting for a response message
* from firmware, as is done on other interconnects.
*
* Yet there is some complexity with direct accesses because the
* Target's power state is not known a priori. The Host must issue
* special PCIe reads/writes in order to explicitly wake the Target
* and to verify that it is awake and will remain awake.
*
* Usage:
/* Target exposes its registers for direct access. However before host can
* access them it needs to make sure the target is awake (ath10k_pci_wake,
* ath10k_pci_wake_wait, ath10k_pci_is_awake). Once target is awake it won't go
* to sleep unless host tells it to (ath10k_pci_sleep).
*
* Use ath10k_pci_read32 and ath10k_pci_write32 to access Target space.
* These calls must be bracketed by ath10k_pci_wake and
* ath10k_pci_sleep. A single BEGIN/END pair is adequate for
* multiple READ/WRITE operations.
* If host tries to access target registers without waking it up it can
* scribble over host memory.
*
* Use ath10k_pci_wake to put the Target in a state in
* which it is legal for the Host to directly access it. This
* may involve waking the Target from a low power state, which
* may take up to 2Ms!
*
* Use ath10k_pci_sleep to tell the Target that as far as
* this code path is concerned, it no longer needs to remain
* directly accessible. BEGIN/END is under a reference counter;
* multiple code paths may issue BEGIN/END on a single targid.
* If target is asleep waking it up may take up to even 2ms.
