Merge backports with 20150424.
Remove part of patch 728e9048c74
"Break the huge lock region of htt tx_lock in tx completion"
because the circular array to track free msdu_ids conflicts with
an upstream change which uses the idr api instead. Changed the lock name
back to tx_lock.
Remove patch 32771de31b1b "Log beacon info."
because it also conflicts and is no longer needed.

- * parport=2,0,1 -- parports 2,0,1 are tried in that order

-/*
- Supported devices:
- *Lifeview FlyCam Supra (using the Philips saa7111a chip)
-
- Does any other model using the w9966 interface chip exist ?
-
- Todo:
-
- *Add a working EPP mode, since DMA ECP read isn't implemented
- in the parport drivers. (That's why it's so sloow)
-
- *Add support for other ccd-control chips than the saa7111
- please send me feedback on what kind of chips you have.
-
- *Add proper probing. I don't know what's wrong with the IEEE1284
- parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
- and nibble read seems to be broken for some peripherals.
-
- *Add probing for onboard SRAM, port directions etc. (if possible)
-
- *Add support for the hardware compressed modes (maybe using v4l2)
-
- *Fix better support for the capture window (no skewed images, v4l
- interface to capt. window)
-
- *Probably some bugs that I don't know of
-
- Please support me by sending feedback!
-
- Changes:
-
- Alan Cox: Removed RGB mode for kernel merge, added THIS_MODULE
- and owner support for newer module locks

+/**
+ * DOC: mac80211 software tx queueing
+ *
+ * mac80211 provides an optional intermediate queueing implementation designed
+ * to allow the driver to keep hardware queues short and provide some fairness
+ * between different stations/interfaces.
+ * In this model, the driver pulls data frames from the mac80211 queue instead
+ * of letting mac80211 push them via drv_tx().
+ * Other frames (e.g. control or management) are still pushed using drv_tx().
+ *
+ * Drivers indicate that they use this model by implementing the .wake_tx_queue
+ * driver operation.
+ *
+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
+ * single per-vif queue for multicast data frames.
+ *
+ * The driver is expected to initialize its private per-queue data for stations
+ * and interfaces in the .add_interface and .sta_add ops.
+ *
+ * The driver can't access the queue directly. To dequeue a frame, it calls
+ * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it
+ * calls the .wake_tx_queue driver op.
+ *
+ * For AP powersave TIM handling, the driver only needs to indicate if it has
+ * buffered packets in the driver specific data structures by calling
+ * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq
+ * struct, mac80211 sets the appropriate TIM PVB bits and calls
+ * .release_buffered_frames().
+ * In that callback the driver is therefore expected to release its own
+ * buffered frames and afterwards also frames from the ieee80211_txq (obtained
+ * via the usual ieee80211_tx_dequeue).

+ * samples are transferred over the bus: "LE" means that the least significant
+ * bits are transferred first, "BE" means that the most significant bits are

+ * in the incomplete high byte, are filled with padding bits.
+ *
+ * The bus formats are grouped by type, bus_width, bits per component, samples
+ * per pixel and order of subsamples. Numerical values are sorted using generic

+ * As their value can't change when a new bus format is inserted in the

- * These pixel codes uniquely identify data formats on the media bus. Mostly
- * they correspond to similarly named V4L2_PIX_FMT_* formats, format 0 is
- * reserved, V4L2_MBUS_FMT_FIXED shall be used by host-client pairs, where the
- * data format is fixed. Additionally, "2X8" means that one pixel is transferred
- * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
- * transferred over the bus: "LE" means that the least significant bits are
- * transferred first, "BE" means that the most significant bits are transferred
- * first, and "PADHI" and "PADLO" define which bits - low or high, in the
- * incomplete high byte, are filled with padding bits.
- *
- * The pixel codes are grouped by type, bus_width, bits per component, samples
- * per pixel and order of subsamples. Numerical values are sorted using generic
- * numerical sort order (8 thus comes before 10).
- *
- * As their value can't change when a new pixel code is inserted in the
- * enumeration, the pixel codes are explicitly given a numerical value. The next
- * free values for each category are listed below, update them when inserting
- * new pixel codes.
