+      <para>
+        Once upon a time, the Small Computer Systems Interface defined both
+        a parallel I/O bus and a data protocol to connect a wide variety of
+        peripherals (disk drives, tape drives, modems, printers, scanners,
+        optical drives, test equipment, and medical devices) to a host
+        computer.
+      </para>
+      <para>
+        Although the old parallel (fast/wide/ultra) SCSI bus has largely
+        fallen out of use, the SCSI command set is more widely used than ever
+        to communicate with devices over a number of different busses.

+      <para>
+        The <ulink url='http://www.t10.org/scsi-3.htm'>SCSI protocol</ulink>
+        is a big-endian peer-to-peer packet based protocol.  SCSI commands
+        are 6, 10, 12, or 16 bytes long, often followed by an associated data
+        payload.
+      </para>
+      <para>
+        SCSI commands can be transported over just about any kind of bus, and
+        are the default protocol for storage devices attached to USB, SATA,
+        SAS, Fibre Channel, FireWire, and ATAPI devices.  SCSI packets are
+        also commonly exchanged over Infiniband,
+        <ulink url='http://i2o.shadowconnect.com/faq.php'>I20</ulink>, TCP/IP

+      <title>Design of the Linux SCSI subsystem</title>
+      <para>
+        The SCSI subsystem uses a three layer design, with upper, mid, and low
+        layers.  Every operation involving the SCSI subsystem (such as reading
+        a sector from a disk) uses one driver at each of the 3 levels: one
+        upper layer driver, one lower layer driver, and the SCSI midlayer.
+      </para>
+      <para>
+        The SCSI upper layer provides the interface between userspace and the
+        kernel, in the form of block and char device nodes for I/O and
+        ioctl().  The SCSI lower layer contains drivers for specific hardware
+        devices.
+      </para>
+      <para>
+        In between is the SCSI mid-layer, analogous to a network routing
+        layer such as the IPv4 stack.  The SCSI mid-layer routes a packet
+        based data protocol between the upper layer's /dev nodes and the
+        corresponding devices in the lower layer.  It manages command queues,
+        provides error handling and power management functions, and responds
+        to ioctl() requests.

+or thread during a set timeframe.  This timeframe is related to, but
+not necessarily exactly the same as, an RCU grace period.  In classic
+RCU, the reference counter is the per-CPU bit in the "bitmask" field,

+About the PCF8575 chip and the pcf8575 kernel driver
+====================================================
+
+The PCF8575 chip is produced by the following manufacturers:
+
+  * Philips NXP
+    http://www.nxp.com/#/pip/cb=[type=product,path=50807/41735/41850,final=PCF8575_3]|pip=[pip=PCF8575_3][0]
+
+  * Texas Instruments
+    http://focus.ti.com/docs/prod/folders/print/pcf8575.html
+
+
+Some vendors sell small PCB's with the PCF8575 mounted on it. You can connect
+such a board to a Linux host via e.g. an USB to I2C interface. Examples of
+PCB boards with a PCF8575:
+
+  * SFE Breakout Board for PCF8575 I2C Expander by RobotShop
+    http://www.robotshop.ca/home/products/robot-parts/electronics/adapters-converters/sfe-pcf8575-i2c-expander-board.html
+
+  * Breakout Board for PCF8575 I2C Expander by Spark Fun Electronics
+    http://www.sparkfun.com/commerce/product_info.php?products_id=8130
+
+
+Description
+-----------
+The PCF8575 chip is a 16-bit I/O expander for the I2C bus. Up to eight of
+these chips can be connected to the same I2C bus. You can find this
+chip on some custom designed hardware, but you won't find it on PC
+motherboards.
+
+The PCF8575 chip consists of a 16-bit quasi-bidirectional port and an I2C-bus
+interface. Each of the sixteen I/O's can be independently used as an input or
+an output. To set up an I/O pin as an input, you have to write a 1 to the
+corresponding output.
+
+For more information please see the datasheet.
+
+
+Detection
+---------
+
+There is no method known to detect whether a chip on a given I2C address is
+a PCF8575 or whether it is any other I2C device. So there are two alternatives
+to let the driver find the installed PCF8575 devices:
+- Load this driver after any other I2C driver for I2C devices with addresses
+  in the range 0x20 .. 0x27.
+- Pass the I2C bus and address of the installed PCF8575 devices explicitly to
+  the driver at load time via the probe=... or force=... parameters.
+
+/sys interface
+--------------
+
+For each address on which a PCF8575 chip was found or forced the following
+files will be created under /sys:
+* /sys/bus/i2c/devices/<bus>-<address>/read
+* /sys/bus/i2c/devices/<bus>-<address>/write
+where bus is the I2C bus number (0, 1, ...) and address is the four-digit
+hexadecimal representation of the 7-bit I2C address of the PCF8575
+(0020 .. 0027).
+
+The read file is read-only. Reading it will trigger an I2C read and will hence
+report the current input state for the pins configured as inputs, and the
+current output value for the pins configured as outputs.
+
+The write file is read-write. Writing a value to it will configure all pins
+as output for which the corresponding bit is zero. Reading the write file will
+return the value last written, or -EAGAIN if no value has yet been written to
+the write file.
+
+On module initialization the configuration of the chip is not changed -- the
+chip is left in the state it was already configured in through either power-up
+or through previous I2C write actions.

-README for WarpEngine/A4000T/A4091 SCSI kernels.
-
-Use the following options to disable options in the SCSI driver.
-
-Using amiboot for example.....
-
-To disable Synchronous Negotiation....
-
-	amiboot -k kernel 53c7xx=nosync:0	
-
-To disable Disconnection....
-	
-	amiboot -k kernel 53c7xx=nodisconnect:0
-
-To disable certain SCSI devices...
-
-	amiboot -k kernel 53c7xx=validids:0x3F
-
-	this allows only device ID's 0,1,2,3,4 and 5 for linux to handle.
-	(this is a bitmasked field - i.e. each bit represents a SCSI ID)
-
-These commands work on a per controller basis and use the option 'next' to
-move to the next controller in the system.
-
-e.g.
-	amiboot -k kernel 53c7xx=nodisconnect:0,next,nosync:0
-
-	this uses No Disconnection on the first controller and Asynchronous
-	SCSI on the second controller.
-
-Known Issues:
-
-Two devices are known not to function with the default settings of using
-synchronous SCSI. These are the Archive Viper 150 Tape Drive and the 
-SyQuest SQ555 removeable hard drive. When using these devices on a controller
-use the 'nosync:0' option.
-
-Please try these options and post any problems/successes to me.

+ * We do not have hardware single-stepping on ARM, This

+ * "next PC" register.  Instructions that change the PC
+ * can't be safely single-stepped in a MP environment, so
+ * we have a lot of work to do:
+ *
+ * In the prepare phase:
+ *   *) If it is an instruction that does anything
+ *      with the CPU mode, we reject it for a kprobe.
+ *      (This is out of laziness rather than need.  The
+ *      instructions could be simulated.)
+ *
+ *   *) Otherwise, decode the instruction rewriting its
+ *      registers to take fixed, ordered registers and
+ *      setting a handler for it to run the instruction.
+ *
+ * In the execution phase by an instruction's handler:
+ *
+ *   *) If the PC is written to by the instruction, the
+ *      instruction must be fully simulated in software.
+ *      If it is a conditional instruction, the handler
+ *      will use insn[0] to copy its condition code to
+ *	set r0 to 1 and insn[1] to "mov pc, lr" to return.
+ *
+ *   *) Otherwise, a modified form of the instruction is
+ *      directly executed.  Its handler calls the
+ *      instruction in insn[0].  In insn[1] is a
+ *      "mov pc, lr" to return.
+ *
+ *      Before calling, load up the reordered registers
+ *      from the original instruction's registers.  If one
+ *      of the original input registers is the PC, compute
+ *      and adjust the appropriate input register.
+ *
+ *	After call completes, copy the output registers to
+ *      the original instruction's original registers.
+ *
+ * We don't use a real breakpoint instruction since that
+ * would have us in the kernel go from SVC mode to SVC
+ * mode losing the link register.  Instead we use an
+ * undefined instruction.  To simplify processing, the
+ * undefined instruction used for kprobes must be reserved
+ * exclusively for kprobes use.

+ * To avoid the complications of mimicing single-stepping on a
+ * processor without a Next-PC or a single-step mode, and to
+ * avoid having to deal with the side-effects of boosting, we
+ * simulate or emulate (almost) all ARM instructions.
+ *
+ * "Simulation" is where the instruction's behavior is duplicated in
+ * C code.  "Emulation" is where the original instruction is rewritten
+ * and executed, often by altering its registers.
+ *
+ * By having all behavior of the kprobe'd instruction completed before
+ * returning from the kprobe_handler(), all locks (scheduler and
+ * interrupt) can safely be released.  There is no need for secondary
+ * breakpoints, no race with MP or preemptable kernels, nor having to
+ * clean up resources counts at a later time impacting overall system
+ * performance.  By rewriting the instruction, only the minimum registers
+ * need to be loaded and saved back optimizing performance.
+ *
+ * Calling the insnslot_*_rwflags version of a function doesn't hurt
+ * anything even when the CPSR flags aren't updated by the
+ * instruction.  It's just a little slower in return for saving
+ * a little space by not having a duplicate function that doesn't
+ * update the flags.  (The same optimization can be said for
+ * instructions that do or don't perform register writeback)
+ * Also, instructions can either read the flags, only write the
+ * flags, or read and write the flags.  To save combinations
+ * rather than for sheer performance, flag functions just assume
+ * read and write of flags.

+ * The Orion has fully programable address map. There's a separate address
+ * map for each of the device _master_ interfaces, e.g. CPU, PCI, PCIE, USB,
+ * Gigabit Ethernet, DMA/XOR engines, etc. Each interface has its own
+ * address decode windows that allow it to access any of the Orion resources.
+ *
+ * CPU address decoding --
+ * Linux assumes that it is the boot loader that already setup the access to
+ * DDR and internal registers.
+ * Setup access to PCI and PCI-E IO/MEM space is issued by core.c.
+ * Setup access to various devices located on the device bus interface (e.g.
+ * flashes, RTC, etc) should be issued by machine-setup.c according to
+ * specific board population (by using orion_setup_cpu_win()).
+ *
+ * Non-CPU Masters address decoding --
+ * Unlike the CPU, we setup the access from Orion's master interfaces to DDR
+ * banks only (the typical use case).
+ * Setup access for each master to DDR is issued by common.c.
+ *
+ * Note: although orion_setbits() and orion_clrbits() are not atomic
+ * no locking is necessary here since code in this file is only called
+ * at boot time when there is no concurrency issues.

+ * Edge IRQ handlers:  Change in DATA_IN are latched in EDGE_CAUSE.

+ *                     This is a race condition that might not perfectly

+ * ABSTRACT:
+ *
+ * The PXA270 processor comes with a bunch of hardware on its silicon.
+ * Not all of this hardware can be used at the same time and not all
+ * is routed to module's connectors. Also it depends on the baseboard, what
+ * kind of hardware can be used in which way.
+ * -> So this file supports the main devices on the CPU card only!
+ * Refer pcm990-baseboard.c how to extend this features to get a full
+ * blown system with many common interfaces.
+ *
+ * The PCM-027 supports the following interfaces through its connectors and
+ * will be used in pcm990-baseboard.c:
+ *
+ * - LCD support
+ * - MMC support
+ * - IDE/CF card
+ * - FFUART
+ * - BTUART
+ * - IRUART
+ * - AC97
+ * - SSP
+ * - SSP3
+ *
+ * Claimed GPIOs:
+ * GPIO0 -> IRQ input from RTC
+ * GPIO2 -> SYS_ENA*)
+ * GPIO3 -> PWR_SCL
+ * GPIO4 -> PWR_SDA
+ * GPIO5 -> PowerCap0*)
+ * GPIO6 -> PowerCap1*)
+ * GPIO7 -> PowerCap2*)
+ * GPIO8 -> PowerCap3*)
+ * GPIO15 -> /CS1
+ * GPIO20 -> /CS2
+ * GPIO21 -> /CS3
+ * GPIO33 -> /CS5 network controller select
+ * GPIO52 -> IRQ from network controller
+ * GPIO78 -> /CS2
+ * GPIO80 -> /CS4
+ * GPIO90 -> LED0
+ * GPIO91 -> LED1
+ * GPIO114 -> IRQ from CAN controller
+ * GPIO117 -> SCL
+ * GPIO118 -> SDA

-	  This is the s390 hardware accelerated implementation of the

-	  algorithm.
-
-	  Rijndael appears to be consistently a very good performer in
-	  both hardware and software across a wide range of computing
-	  environments regardless of its use in feedback or non-feedback
-	  modes. Its key setup time is excellent, and its key agility is
-	  good. Rijndael's very low memory requirements make it very well
-	  suited for restricted-space environments, in which it also
-	  demonstrates excellent performance. Rijndael's operations are
-	  among the easiest to defend against power and timing attacks.
-
-	  On s390 the System z9-109 currently only supports the key size

  * IMPORTANT NOTES :
- * The do_fast_page_fault function is called from a context in entry.S where very few registers
- * have been saved.  In particular, the code in this file must be compiled not to use ANY
- * caller-save registers that are not part of the restricted save set.  Also, it means that
- * code in this file must not make calls to functions elsewhere in the kernel, or else the
- * excepting context will see corruption in its caller-save registers.  Plus, the entry.S save
- * area is non-reentrant, so this code has to run with SR.BL==1, i.e. no interrupts taken inside
- * it and panic on any exception.

-	  Find out whether you have a PCI motherboard. PCI is the name of a
-	  bus system, i.e. the way the CPU talks to the other stuff inside
-	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
-	  VESA. If you have PCI, say Y, otherwise N.
-
-	  The PCI-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>, contains valuable
-	  information about which PCI hardware does work under Linux and which
-	  doesn't.

-config SH_PCIDMA_NONCOHERENT
-	bool "Cache and PCI noncoherent"
-	depends on PCI
-	default y
-	help
-	  Enable this option if your platform does not have a CPU cache which
-	  remains coherent with PCI DMA. It is safest to say 'Y', although you
-	  will see better performance if you can say 'N', because the PCI DMA
-	  code will not have to flush the CPU's caches. If you have a PCI host
-	  bridge integrated with your SH CPU, refer carefully to the chip specs
-	  to see if you can say 'N' here. Otherwise, leave it as 'Y'.

+ * Serial ATA Index/Data Pair Superset Registers access

+ * Beginning from ICH8, there's a sane way to access SCRs using index

+ * interesting problem of mapping two SCRs to one port.
+ *
+ * Although they have separate SCRs, the master and slave aren't
+ * independent enough to be treated as separate links - e.g. softreset
+ * resets both.  Also, there's no protocol defined for hard resetting
+ * singled device sharing the virtual port (no defined way to acquire
+ * device signature).  This is worked around by merging the SCR values
+ * into one sensible value and requesting follow-up SRST after
+ * hardreset.
+ *
+ * SCR merging is perfomed in nibbles which is the unit contents in
+ * SCRs are organized.  If two values are equal, the value is used.
+ * When they differ, merge table which lists precedence of possible
+ * values is consulted and the first match or the last entry when
+ * nothing matches is used.  When there's no merge table for the
+ * specific nibble, value from the first port is used.

+   Basic firmware description. This will remain with
+   the driver for documentation purposes.
+
+   This represents an I2C firmware file encoded as a
+   string of unsigned char. Format is as follows:
+
+   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
+   char[1  ]=len0_LSB  -> length of first write transaction
+   char[2  ]=data0 -> first byte to be sent
+   char[3  ]=data1
+   char[4  ]=data2
+   char[   ]=...
+   char[M  ]=dataN  -> last byte to be sent
+   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
+   char[M+2]=len1_LSB  -> length of second write transaction
+   char[M+3]=data0
+   char[M+4]=data1
+   ...
+   etc.
+
+   The [len] value should be interpreted as follows:
+
+   len= len_MSB _ len_LSB
+   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
+   len=0000_0000_0000_0000   : Reset command: Do hardware reset
+   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
+   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
+
+   For the RESET and WAIT commands, the two following bytes will contain
+   immediately the length of the following transaction.

+/*
+ * History:
+ * 2008-01-12	Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.0
+ *		- First working version
+ * 2008-01-13   Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.1
+ *		- Improved error handling, every function now returns errno
+ *		- Improved multi user access (start/mute/stop)
+ *		- Channel doesn't get lost anymore after start/mute/stop
+ *		- RDS support added (polling mode via interrupt EP 1)
+ *		- marked default module parameters with *value*
+ *		- switched from bit structs to bit masks
+ *		- header file cleaned and integrated
+ * 2008-01-14	Tobias Lorenz <tobias.lorenz@gmx.net>
+ * 		Version 1.0.2
+ * 		- hex values are now lower case
+ * 		- commented USB ID for ADS/Tech moved on todo list
+ * 		- blacklisted si470x in hid-quirks.c
+ * 		- rds buffer handling functions integrated into *_work, *_read
+ * 		- rds_command in si470x_poll exchanged against simple retval
+ * 		- check for firmware version 15
+ * 		- code order and prototypes still remain the same
+ * 		- spacing and bottom of band codes remain the same
+ * 2008-01-16	Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.3
+ * 		- code reordered to avoid function prototypes
+ *		- switch/case defaults are now more user-friendly
+ *		- unified comment style
+ *		- applied all checkpatch.pl v1.12 suggestions
+ *		  except the warning about the too long lines with bit comments
+ *		- renamed FMRADIO to RADIO to cut line length (checkpatch.pl)
+ * 2008-01-22	Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.4
+ *		- avoid poss. locking when doing copy_to_user which may sleep
+ *		- RDS is automatically activated on read now
+ *		- code cleaned of unnecessary rds_commands
+ *		- USB Vendor/Product ID for ADS/Tech FM Radio Receiver verified
+ *		  (thanks to Guillaume RAMOUSSE)
+ *
+ * ToDo:
+ * - add seeking support
+ * - add firmware download/update support
+ * - RDS support: interrupt mode, instead of polling
+ * - add LED status output (check if that's not already done in firmware)

+	  This is not required for em2800/em2820/em2821 boards. However,
+	  newer em28xx devices uses Vendor Class for audio, instead of
+	  implementing the USB Audio Class. For those chips, this module
+	  will enable digital audio.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called em28xx-alsa

-/*
-
-  This single function is key to pretty much everything.  The pvrusb2
-  device can logically be viewed as a series of subsystems which can be
-  stopped / started or unconfigured / configured.  To get things streaming,
-  one must configure everything and start everything, but there may be
-  various reasons over time to deconfigure something or stop something.
-  This function handles all of this activity.  Everything EVERYWHERE that
-  must affect a subsystem eventually comes here to do the work.
-
-  The current state of all subsystems is represented by a single bit mask,
-  known as subsys_enabled_mask.  The bit positions are defined by the
-  PVR2_SUBSYS_xxxx macros, with one subsystem per bit position.  At any
-  time the set of configured or active subsystems can be queried just by
-  looking at that mask.  To change bits in that mask, this function here
-  must be called.  The "msk" argument indicates which bit positions to
-  change, and the "val" argument defines the new values for the positions
-  defined by "msk".
-
-  There is a priority ordering of starting / stopping things, and for
-  multiple requested changes, this function implements that ordering.
-  (Thus we will act on a request to load encoder firmware before we
-  configure the encoder.)  In addition to priority ordering, there is a
-  recovery strategy implemented here.  If a particular step fails and we
-  detect that failure, this function will clear the affected subsystem bits
-  and restart.  Thus we have a means for recovering from a dead encoder:
-  Clear all bits that correspond to subsystems that we need to restart /
-  reconfigure and start over.

+ *   device is checked by the eckd discipline and
+ *   dasd_alias_disconnect_device_from_lcu will be called
+ *   before the device is deleted.
+ * - The dasd_alias_add_device / dasd_alias_remove_device
+ *   functions mark the point when a device is 'ready for service'.
+ * - A summary unit check is a rare occasion, but it is mandatory to
+ *   support it. It requires some complex recovery actions before the
+ *   devices can be used again (see dasd_alias_handle_summary_unit_check).
+ * - dasd_alias_get_start_dev will find an alias device that can be used
+ *   instead of the base device and does some (very simple) load balancing.
+ *   This is the function that gets called for each I/O, so when improving
+ *   something, this function should get faster or better, the rest has just

- * Configuration :
- * To use without BIOS -DOVERRIDE=base_address -DCONTROLLER=FD or SEAGATE
- * -DIRQ will override the default of 5.
- * Note: You can now set these options from the kernel's "command line".
- * The syntax is:
- *
- *     st0x=ADDRESS,IRQ                (for a Seagate controller)
- * or:
- *     tmc8xx=ADDRESS,IRQ              (for a TMC-8xx or TMC-950 controller)
- * eg:
- *     tmc8xx=0xC8000,15
- *
- * will configure the driver for a TMC-8xx style controller using IRQ 15
- * with a base address of 0xC8000.
- *
- * -DARBITRATE 
- *      Will cause the host adapter to arbitrate for the
- *      bus for better SCSI-II compatibility, rather than just
- *      waiting for BUS FREE and then doing its thing.  Should
- *      let us do one command per Lun when I integrate my
- *      reorganization changes into the distribution sources.
- *
- * -DDEBUG=65535
- *      Will activate debug code.
- *
- * -DFAST or -DFAST32 
- *      Will use blind transfers where possible
- *
- * -DPARITY  
- *      This will enable parity.
- *
- * -DSEAGATE_USE_ASM
- *      Will use older seagate assembly code. should be (very small amount)
- *      Faster.
- *
- * -DSLOW_RATE=50
- *      Will allow compatibility with broken devices that don't
- *      handshake fast enough (ie, some CD ROM's) for the Seagate
- *      code.
- *
- *      50 is some number, It will let you specify a default
- *      transfer rate if handshaking isn't working correctly.
- *
- * -DOLDCNTDATASCEME  There is a new sceme to set the CONTROL
- *                    and DATA reigsters which complies more closely
- *                    with the SCSI2 standard. This hopefully eliminates
- *                    the need to swap the order these registers are
- *                    'messed' with. It makes the following two options
- *                    obsolete. To reenable the old sceme define this.
- *
- * The following to options are patches from the SCSI.HOWTO
- *
- * -DSWAPSTAT  This will swap the definitions for STAT_MSG and STAT_CD.
- *
- * -DSWAPCNTDATA  This will swap the order that seagate.c messes with
- *                the CONTROL an DATA registers.

- * Support for broken devices :
- * The Seagate board has a handshaking problem.  Namely, a lack
- * thereof for slow devices.  You can blast 600K/second through
- * it if you are polling for each byte, more if you do a blind
- * transfer.  In the first case, with a fast device, REQ will
- * transition high-low or high-low-high before your loop restarts
- * and you'll have no problems.  In the second case, the board
- * will insert wait states for up to 13.2 usecs for REQ to
- * transition low->high, and everything will work.
- *
- * However, there's nothing in the state machine that says
- * you *HAVE* to see a high-low-high set of transitions before
- * sending the next byte, and slow things like the Trantor CD ROMS
- * will break because of this.
- *
- * So, we need to slow things down, which isn't as simple as it
- * seems.  We can't slow things down period, because then people
- * who don't recompile their kernels will shoot me for ruining
- * their performance.  We need to do it on a case per case basis.
- *
- * The best for performance will be to, only for borken devices
- * (this is stored on a per-target basis in the scsi_devices array)
- *
- * Wait for a low->high transition before continuing with that
- * transfer.  If we timeout, continue anyways.  We don't need
- * a long timeout, because REQ should only be asserted until the
- * corresponding ACK is received and processed.
- *
- * Note that we can't use the system timer for this, because of
- * resolution, and we *really* can't use the timer chip since
- * gettimeofday() and the beeper routines use that.  So,
- * the best thing for us to do will be to calibrate a timing

- * Hardware and software bit definitions for the PTEL value (see below for
- * notes on SH-X2 MMUs and 64-bit PTEs):
- *
- * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
- *
- * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
- *   hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
- *   which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
- *
- *   In order to keep this relatively clean, do not use these for defining
- *   SH-3 specific flags until all of the other unused bits have been
- *   exhausted.
- *
- * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
- *
- * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
- *   Bit 10 is used for _PAGE_ACCESSED, bit 11 remains unused.
- *
- * - Bits 31, 30, and 29 remain unused by everyone and can be used for future
- *   software flags, although care must be taken to update _PAGE_CLEAR_FLAGS.
- *
- * XXX: Leave the _PAGE_FILE and _PAGE_WT overhaul for a rainy day.
- *
- * SH-X2 MMUs and extended PTEs
- *
- * SH-X2 supports an extended mode TLB with split data arrays due to the
- * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
- * SZ bit placeholders still exist in data array 1, but are implemented as
- * reserved bits, with the real logic existing in data array 2.
- *
- * The downside to this is that we can no longer fit everything in to a 32-bit
- * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
- * side, this gives us quite a few spare bits to play with for future usage.

+ * Linux PTEL encoding.
+ *
+ * Hardware and software bit definitions for the PTEL value (see below for
+ * notes on SH-X2 MMUs and 64-bit PTEs):
+ *
+ * - Bits 0 and 7 are reserved on SH-3 (_PAGE_WT and _PAGE_SZ1 on SH-4).
+ *
+ * - Bit 1 is the SH-bit, but is unused on SH-3 due to an MMU bug (the
+ *   hardware PTEL value can't have the SH-bit set when MMUCR.IX is set,
+ *   which is the default in cpu-sh3/mmu_context.h:MMU_CONTROL_INIT).
+ *
+ *   In order to keep this relatively clean, do not use these for defining
+ *   SH-3 specific flags until all of the other unused bits have been
+ *   exhausted.
+ *
+ * - Bit 9 is reserved by everyone and used by _PAGE_PROTNONE.
+ *
+ * - Bits 10 and 11 are low bits of the PPN that are reserved on >= 4K pages.
+ *   Bit 10 is used for _PAGE_ACCESSED, bit 11 remains unused.
+ *
+ * - On 29 bit platforms, bits 31 to 29 are used for the space attributes
+ *   and timing control which (together with bit 0) are moved into the
+ *   old-style PTEA on the parts that support it.
+ *
+ * XXX: Leave the _PAGE_FILE and _PAGE_WT overhaul for a rainy day.
+ *
+ * SH-X2 MMUs and extended PTEs
+ *
+ * SH-X2 supports an extended mode TLB with split data arrays due to the
+ * number of bits needed for PR and SZ (now EPR and ESZ) encodings. The PR and
+ * SZ bit placeholders still exist in data array 1, but are implemented as
+ * reserved bits, with the real logic existing in data array 2.
+ *
+ * The downside to this is that we can no longer fit everything in to a 32-bit
+ * PTE encoding, so a 64-bit pte_t is necessary for these parts. On the plus
+ * side, this gives us quite a few spare bits to play with for future usage.

- * Core file format: The core file is written in such a way that gdb
- * can understand it and provide useful information to the user (under
- * linux we use the `trad-core' bfd).  The file contents are as follows:
- *
- *  upage: 1 page consisting of a user struct that tells gdb
- *	what is present in the file.  Directly after this is a
- *	copy of the task_struct, which is currently not used by gdb,
- *	but it may come in handy at some point.  All of the registers
- *	are stored as part of the upage.  The upage should always be
- *	only one page long.
- *  data: The data segment follows next.  We use current->end_text to
- *	current->brk to pick up all of the user variables, plus any memory
- *	that may have been sbrk'ed.  No attempt is made to determine if a
- *	page is demand-zero or if a page is totally unused, we just cover
- *	the entire range.  All of the addresses are rounded in such a way
- *	that an integral number of pages is written.
- *  stack: We need the stack information in order to get a meaningful
- *	backtrace.  We need to write the data from usp to
- *	current->start_stack, so we round each of these in order to be able
- *	to write an integer number of pages.

- * DLM_LKF_VALBLK
- *
- * Requests DLM to return the current contents of the lock value block in the

- *
- * DLM_LKF_NOQUEUEBAST
