+ * Libata transport class.
+ *
+ * The ATA transport class contains common code to deal with ATA HBAs,
+ * an approximated representation of ATA topologies in the driver model,
+ * and various sysfs attributes to expose these topologies and management
+ * interfaces to user-space.
+ *
+ * There are 3 objects defined in in this class:
+ * - ata_port
+ * - ata_link
+ * - ata_device
+ * Each port has a link object. Each link can have up to two devices for PATA
+ * and generally one for SATA.
+ * If there is SATA port multiplier [PMP], 15 additional ata_link object are
+ * created.
+ *
+ * These objects are created when the ata host is initialized and when a PMP is
+ * found. They are removed only when the HBA is removed, cleaned before the
+ * error handler runs.

+
+
+   Instructions for use
+   --------------------
+
+   1) Map a Linux block device to an existing rbd image.
+
+      Usage: <mon ip addr> <options> <pool name> <rbd image name> [snap name]
+
+      $ echo "192.168.0.1 name=admin rbd foo" > /sys/class/rbd/add
+
+      The snapshot name can be "-" or omitted to map the image read/write.
+
+   2) List all active blkdev<->object mappings.
+
+      In this example, we have performed step #1 twice, creating two blkdevs,
+      mapped to two separate rados objects in the rados rbd pool
+
+      $ cat /sys/class/rbd/list
+      #id     major   client_name     pool    name    snap    KB
+      0       254     client4143      rbd     foo     -      1024000
+
+      The columns, in order, are:
+      - blkdev unique id
+      - blkdev assigned major
+      - rados client id
+      - rados pool name
+      - rados block device name
+      - mapped snapshot ("-" if none)
+      - device size in KB
+
+
+   3) Create a snapshot.
+
+      Usage: <blkdev id> <snapname>
+
+      $ echo "0 mysnap" > /sys/class/rbd/snap_create
+
+
+   4) Listing a snapshot.
+
+      $ cat /sys/class/rbd/snaps_list
+      #id     snap    KB
+      0       -       1024000 (*)
+      0       foo     1024000
+
+      The columns, in order, are:
+      - blkdev unique id
+      - snapshot name, '-' means none (active read/write version)
+      - size of device at time of snapshot
+      - the (*) indicates this is the active version
+
+   5) Rollback to snapshot.
+
+      Usage: <blkdev id> <snapname>
+
+      $ echo "0 mysnap" > /sys/class/rbd/snap_rollback
+
+
+   6) Mapping an image using snapshot.
+
+      A snapshot mapping is read-only. This is being done by passing
+      snap=<snapname> to the options when adding a device.
+
+      $ echo "192.168.0.1 name=admin,snap=mysnap rbd foo" > /sys/class/rbd/add
+
+
+   7) Remove an active blkdev<->rbd image mapping.
+
+      In this example, we remove the mapping with blkdev unique id 1.
+
+      $ echo 1 > /sys/class/rbd/remove
+
+
+   NOTE:  The actual creation and deletion of rados objects is outside the scope
+   of this driver.

+ * There exists an official driver on the manufacturer's website, which

+ *
+ * It shows that the feature report ID 2 could be used to control any waltop
+ * tablet input mode, switching it between "default", "tablet" and "ink".
+ *
+ * This driver only uses "default" mode for all the supported tablets. This
+ * mode tries to be HID-compatible (not very successfully), but cripples the
+ * resolution of some tablets.
+ *
+ * The "tablet" mode uses some proprietary, yet decipherable protocol, which
+ * represents the correct resolution, but is possibly HID-incompatible (i.e.
+ * indescribable by a report descriptor).
+ *
+ * The purpose of the "ink" mode is unknown.
+ *
+ * The feature reports needed for switching to each mode are these:
+ *
+ * 02 16 00     default
+ * 02 16 01     tablet
+ * 02 16 02     ink

+ * Original Media Tablet 10.6 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
+ * (newer version).
+ *
+ * Both versions have the usual pen with two barrel buttons and two
+ * identical wheels with center buttons in the top corners of the tablet
+ * base. They also have buttons on the top, between the wheels, for
+ * selecting the wheels' functions and wide/standard mode. In the wide mode
+ * the whole working surface is sensed, in the standard mode a narrower area
+ * is sensed, but the logical report extents remain the same. These modes
+ * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
+ *
+ * The older version has three wheel function buttons ("scroll", "zoom" and
+ * "volume") and two separate buttons for wide and standard mode. The newer
+ * version has four wheel function buttons (plus "brush") and only one
+ * button is used for selecting wide/standard mode. So, the total number of
+ * buttons remains the same, but one of the mode buttons is repurposed as a
+ * wheels' function button in the newer version.
+ *
+ * The wheel functions are:
+ * scroll   - the wheels act as scroll wheels, the center buttons switch
+ *            between vertical and horizontal scrolling;
+ * zoom     - the wheels zoom in/out, the buttons supposedly reset to 100%;
+ * volume   - the wheels control the sound volume, the buttons mute;
+ * brush    - the wheels are supposed to control brush width in a graphics
+ *            editor, the buttons do nothing.
+ *
+ * Below is the newer version's report descriptor. It may very well be that
+ * the older version's descriptor is different and thus it won't be
+ * supported.
+ *
+ * The mouse report (ID 1) only uses the wheel field for reporting the tablet
+ * wheels' scroll mode. The keyboard report (ID 13) is used to report the
+ * wheels' zoom and brush control functions as key presses. The report ID 12
+ * is used to report the wheels' volume control functions. The stylus report
+ * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
+ *
+ * The rest of the reports are unused, at least in the default configuration.
+ * The purpose of the features is unknown.

+ * Original Media Tablet 14.1 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
+ * (newer version). The hardware difference between these versions is the same
+ * as between older and newer versions of Media Tablet 10.6 inch. The report
+ * descriptors are identical for both versions.
+ *
+ * The function, behavior and report descriptor of this tablet is similar to
+ * that of Media Tablet 10.6 inch. However, there is one more field (with
+ * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
+ * logical extents both get scaled to 0..16383 range (a hardware limit?),
+ * which kind of defeats the advertised 4000 LPI resolution, considering the
+ * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
+ * sometimes (while moving the pen) with unknown purpose. Also, the key codes
+ * generated for zoom in/out are different.

+ * The PCA9541 is a bus master selector. It supports two I2C masters connected
+ * to a single slave bus.
+ *
+ * Before each bus transaction, a master has to acquire bus ownership. After the
+ * transaction is complete, bus ownership has to be released. This fits well
+ * into the I2C multiplexer framework, which provides select and release
+ * functions for this purpose. For this reason, this driver is modeled as
+ * single-channel I2C bus multiplexer.
+ *
+ * This driver assumes that the two bus masters are controlled by two different
+ * hosts. If a single host controls both masters, platform code has to ensure
+ * that only one of the masters is instantiated at any given time.

+ *    many warnings and error messages. The idea is that we do not lose
+ *    important data in these case - we may lose only the data which was being
+ *    written to the media just before the power cut happened, and the upper

+ *    erasure.
+ *
+ * 2. Unexpected corruptions which are not caused by power cuts. During
+ *    scanning, such PEBs are put to the @corr list and UBI preserves them.
+ *    Obviously, this lessens the amount of available PEBs, and if at some
+ *    point UBI runs out of free PEBs, it switches to R/O mode. UBI also loudly
+ *    informs about such PEBs every time the MTD device is attached.
+ *
+ * However, it is difficult to reliably distinguish between these types of

+ *
+ * @ah: The &struct ath5k_hw
+ * @intval: beacon interval
+ *
+ * This is a workaround for IBSS mode:
+ *
+ * The need for this function arises from the fact that we have 4 separate
+ * HW timer registers (TIMER0 - TIMER3), which are closely related to the
+ * next beacon target time (NBTT), and that the HW updates these timers
+ * seperately based on the current TSF value. The hardware increments each
+ * timer by the beacon interval, when the local TSF coverted to TU is equal
+ * to the value stored in the timer.
+ *
+ * The reception of a beacon with the same BSSID can update the local HW TSF
+ * at any time - this is something we can't avoid. If the TSF jumps to a
+ * time which is later than the time stored in a timer, this timer will not
+ * be updated until the TSF in TU wraps around at 16 bit (the size of the
+ * timers) and reaches the time which is stored in the timer.
+ *
+ * The problem is that these timers are closely related to TIMER0 (NBTT) and
+ * that they define a time "window". When the TSF jumps between two timers
+ * (e.g. ATIM and NBTT), the one in the past will be left behind (not
+ * updated), while the one in the future will be updated every beacon
+ * interval. This causes the window to get larger, until the TSF wraps
+ * around as described above and the timer which was left behind gets
+ * updated again. But - because the beacon interval is usually not an exact
+ * divisor of the size of the timers (16 bit), an unwanted "window" between
+ * these timers has developed!
+ *
+ * This is especially important with the ATIM window, because during
+ * the ATIM window only ATIM frames and no data frames are allowed to be
+ * sent, which creates transmission pauses after each beacon. This symptom
+ * has been described as "ramping ping" because ping times increase linearly
+ * for some time and then drop down again. A wrong window on the DMA beacon
+ * timer has the same effect, so we check for these two conditions.
+ *
+ * Returns true if O.K.

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

- * 					   - io-tag can be reused.
- *
- * 	BFA_IOIM_STS_SCSI_ERR		: IO completed with scsi error.
- * 					  - io-tag can be reused.
- *
- * 	BFI_IOIM_STS_HOST_ABORTED	: IO was aborted successfully due to
- *					   host request.
- * 					   - io-tag cannot be reused yet.
- *
- * 	BFI_IOIM_STS_ABORTED		: IO was aborted successfully
- *					   internally by f/w.
- * 					   - io-tag cannot be reused yet.
- *
- * 	BFI_IOIM_STS_TIMEDOUT	: IO timedout and ABTS/RRQ is happening
- *					   in the firmware and
- * 					   - io-tag cannot be reused yet.
- *
- * 	BFI_IOIM_STS_SQER_NEEDED	: Firmware could not recover the IO
- *					  with sequence level error
- * 					  logic and hence host needs to retry
- *					  this IO with a different IO tag
- * 					  - io-tag cannot be used yet.
- *
- * 	BFI_IOIM_STS_NEXUS_ABORT	: Second Level Error Recovery from host
- *					  is required because 2 consecutive ABTS
- *					  timedout and host needs logout and
- *					  re-login with the target
- * 					  - io-tag cannot be used yet.
- *
- * 	BFI_IOIM_STS_UNDERRUN	: IO completed with SCSI status good,
- *					  but the data tranferred is less than
- *					  the fcp data length in the command.
- *					  ex. SCSI INQUIRY where transferred
- *					  data length and residue count in FCP
- *					  response accounts for total fcp-dl
- * 					  - io-tag can be reused.
- *
- * 	BFI_IOIM_STS_OVERRUN	: IO completed with SCSI status good,
- *					  but the data transerred is more than
- *					  fcp data length in the command. ex.
- *					  TAPE IOs where blocks can of unequal
- *					  lengths.
- * 					  - io-tag can be reused.
- *
- * 	BFI_IOIM_STS_RES_FREE	: Firmware has completed using io-tag
- *					  during abort process
- * 					  - io-tag can be reused.
- *
- * 	BFI_IOIM_STS_PROTO_ERR	: Firmware detected a protocol error.
- *					  ex target sent more data than
- *					  requested, or there was data frame
- *					  loss and other reasons
- * 					  - io-tag cannot be used yet.
- *
- * 	BFI_IOIM_STS_DIF_ERR	: Firwmare detected DIF error. ex: DIF
- * 					  CRC err or Ref Tag err or App tag err.
- * 					  - io-tag can be reused.
- *
- * 	BFA_IOIM_STS_TSK_MGT_ABORT	: IO was aborted because of Task
- *					  Management command from the host
- * 					  - io-tag can be reused.
- *
- * 	BFI_IOIM_STS_UTAG		: Firmware does not know about this

-* Description:  The block table stores bad block info, including MDF+
-*               blocks gone bad over the ages. Therefore, if we have a
-*               block table in place, then use it to scan for bad blocks
-*               If not, then scan for MDF.
-*               Now, a block table will only be found if spectra was already
-*               being used. For a fresh flash, we'll go thru scanning for
-*               MDF. If spectra was being used, then there is a chance that
-*               the MDF has been corrupted. Spectra avoids writing to the
-*               first 2 bytes of the spare area to all pages in a block. This
-*               covers all known flash devices. However, since flash
-*               manufacturers have no standard of where the MDF is stored,
-*               this cannot guarantee that the MDF is protected for future
-*               devices too. The initial scanning for the block table assures
-*               this. It is ok even if the block table is outdated, as all
-*               we're looking for are bad block markers.
-*               Use this when mounting a file system or starting a
-*               new flash.

+ * translating bus (DMA) to virtual and vice-versa and also providing a
+ * mechanism to have contiguous pages for device drivers operations (say DMA
+ * operations).
+ *
+ * Specifically, under Xen the Linux idea of pages is an illusion. It
+ * assumes that pages start at zero and go up to the available memory. To
+ * help with that, the Linux Xen MMU provides a lookup mechanism to
+ * translate the page frame numbers (PFN) to machine frame numbers (MFN)
+ * and vice-versa. The MFN are the "real" frame numbers. Furthermore
+ * memory is not contiguous. Xen hypervisor stitches memory for guests
+ * from different pools, which means there is no guarantee that PFN==MFN
+ * and PFN+1==MFN+1. Lastly with Xen 4.0, pages (in debug mode) are
+ * allocated in descending order (high to low), meaning the guest might
+ * never get any MFN's under the 4GB mark.
