++	  You may want to read <file:Documentation/usb/uhci.txt>.

++config USB_EHCI_ROOT_HUB_TT

++	---help---
++	  Some EHCI chips have vendor-specific extensions to integrate
++	  transaction translators, so that no OHCI or UHCI companion
++	  controller is needed.  It's safe to say "y" even if your
++	  controller doesn't support this feature.
++
++	  This supports the EHCI implementation from TransDimension Inc.

++ * The UHCI driver uses QHs with Interrupt, Control and Bulk URBs for

++ * automatic queuing. To make it easy to insert entries into the schedule,

++ * we have a skeleton of QHs for each predefined Interrupt latency.

++ * Asynchronous QHs (low-speed control, full-speed control, and bulk)

++ * go onto the period-1 interrupt list, since they all get accessed on

++ * every frame.

++ *

++ * When we want to add a new QH, we add it to the list starting from the

++ * appropriate skeleton QH.  For instance, the schedule can look like this:

++ *

++ * skel int128 QH

++ * dev 1 interrupt QH

++ * dev 5 interrupt QH

++ * skel int64 QH

++ * skel int32 QH

++ * ...

++ * skel int1 + async QH

++ * dev 5 low-speed control QH

++ * dev 1 bulk QH

++ * dev 2 bulk QH

++ *

++ * There is a special terminating QH used to keep full-speed bandwidth

++ * reclamation active when no full-speed control or bulk QHs are linked

++ * into the schedule.  It has an inactive TD (to work around a PIIX bug,

++ * see the Intel errata) and it points back to itself.

++ *

++ * There's a special skeleton QH for Isochronous QHs which never appears

++ * on the schedule.  Isochronous TDs go on the schedule before the

++ * the skeleton QHs.  The hardware accesses them directly rather than

++ * through their QH, which is used only for bookkeeping purposes.

++ * While the UHCI spec doesn't forbid the use of QHs for Isochronous,

++ * it doesn't use them either.  And the spec says that queues never

++ * advance on an error completion status, which makes them totally

++ * unsuitable for Isochronous transfers.

++ *

++ * There's also a special skeleton QH used for QHs which are in the process

++ * of unlinking and so may still be in use by the hardware.  It too never

++ * appears on the schedule.

++Author: Guenter Roeck <linux@roeck-us.net>
++
++
++Description
++-----------
++
++This driver supports hardware montoring for various PMBus compliant devices.
++It supports voltage, current, power, and temperature sensors as supported
++by the device.
++
++Each monitored channel has its own high and low limits, plus a critical
++limit.
++
++Fan support will be added in a later version of this driver.
++
++
++Usage Notes
++-----------
++
++This driver does not probe for PMBus devices, since there is no register
++which can be safely used to identify the chip (The MFG_ID register is not
++supported by all chips), and since there is no well defined address range for
++PMBus devices. You will have to instantiate the devices explicitly.
++
++Example: the following will load the driver for an LTC2978 at address 0x60
++on I2C bus #1:
++$ modprobe pmbus
++[KML:  Not for the backport]
++$ echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
++
++
++Platform data support
++---------------------
++
++Support for additional PMBus chips can be added by defining chip parameters in
++a new chip specific driver file. For example, (untested) code to add support for
++Emerson DS1200 power modules might look as follows.
++
++static struct pmbus_driver_info ds1200_info = {
++	.pages = 1,
++	/* Note: All other sensors are in linear mode */
++	.direct[PSC_VOLTAGE_OUT] = true,
++	.direct[PSC_TEMPERATURE] = true,
++	.direct[PSC_CURRENT_OUT] = true,
++	.m[PSC_VOLTAGE_IN] = 1,
++	.b[PSC_VOLTAGE_IN] = 0,
++	.R[PSC_VOLTAGE_IN] = 3,
++	.m[PSC_VOLTAGE_OUT] = 1,
++	.b[PSC_VOLTAGE_OUT] = 0,
++	.R[PSC_VOLTAGE_OUT] = 3,
++	.m[PSC_TEMPERATURE] = 1,
++	.b[PSC_TEMPERATURE] = 0,
++	.R[PSC_TEMPERATURE] = 3,
++	.func[0] = PMBUS_HAVE_VIN | PMBUS_HAVE_IIN | PMBUS_HAVE_STATUS_INPUT
++		   | PMBUS_HAVE_VOUT | PMBUS_HAVE_STATUS_VOUT
++		   | PMBUS_HAVE_IOUT | PMBUS_HAVE_STATUS_IOUT
++		   | PMBUS_HAVE_PIN | PMBUS_HAVE_POUT
++		   | PMBUS_HAVE_TEMP | PMBUS_HAVE_STATUS_TEMP
++		   | PMBUS_HAVE_FAN12 | PMBUS_HAVE_STATUS_FAN12,

++PMBus core driver and internal API
++==================================
++
++Introduction
++============
++
++[from pmbus.org] The Power Management Bus (PMBus) is an open standard
++power-management protocol with a fully defined command language that facilitates
++communication with power converters and other devices in a power system. The
++protocol is implemented over the industry-standard SMBus serial interface and
++enables programming, control, and real-time monitoring of compliant power
++conversion products. This flexible and highly versatile standard allows for
++communication between devices based on both analog and digital technologies, and
++provides true interoperability which will reduce design complexity and shorten
++time to market for power system designers. Pioneered by leading power supply and
++semiconductor companies, this open power system standard is maintained and
++promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters
++with the objective to provide support to, and facilitate adoption among, users.
++
++Unfortunately, while PMBus commands are standardized, there are no mandatory
++commands, and manufacturers can add as many non-standard commands as they like.
++Also, different PMBUs devices act differently if non-supported commands are
++executed. Some devices return an error, some devices return 0xff or 0xffff and
++set a status error flag, and some devices may simply hang up.
++
++Despite all those difficulties, a generic PMBus device driver is still useful
++and supported since kernel version 2.6.39. However, it was necessary to support
++device specific extensions in addition to the core PMBus driver, since it is
++simply unknown what new device specific functionality PMBus device developers
++come up with next.
++
++To make device specific extensions as scalable as possible, and to avoid having
++to modify the core PMBus driver repeatedly for new devices, the PMBus driver was
++split into core, generic, and device specific code. The core code (in
++pmbus_core.c) provides generic functionality. The generic code (in pmbus.c)
++provides support for generic PMBus devices. Device specific code is responsible
++for device specific initialization and, if needed, maps device specific
++functionality into generic functionality. This is to some degree comparable
++to PCI code, where generic code is augmented as needed with quirks for all kinds
++of devices.
++
++PMBus device capabilities auto-detection
++========================================
++
++For generic PMBus devices, code in pmbus.c attempts to auto-detect all supported
++PMBus commands. Auto-detection is somewhat limited, since there are simply too
++many variables to consider. For example, it is almost impossible to autodetect
++which PMBus commands are paged and which commands are replicated across all
++pages (see the PMBus specification for details on multi-page PMBus devices).
++
++For this reason, it often makes sense to provide a device specific driver if not
++all commands can be auto-detected. The data structures in this driver can be
++used to inform the core driver about functionality supported by individual
++chips.
++
++Some commands are always auto-detected. This applies to all limit commands
++(lcrit, min, max, and crit attributes) as well as associated alarm attributes.
++Limits and alarm attributes are auto-detected because there are simply too many
++possible combinations to provide a manual configuration interface.
++
++PMBus internal API
++==================
++
++The API between core and device specific PMBus code is defined in
++drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines
++standard PMBus commands and virtual PMBus commands.
++
++Standard PMBus commands
++-----------------------
++
++Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs
++specification.
++
++Virtual PMBus commands
++----------------------
++
++Virtual PMBus commands are provided to enable support for non-standard
++functionality which has been implemented by several chip vendors and is thus
++desirable to support.
++
++Virtual PMBus commands start with command value 0x100 and can thus easily be
++distinguished from standard PMBus commands (which can not have values larger
++than 0xff). Support for virtual PMBus commands is device specific and thus has
++to be implemented in device specific code.
++
++Virtual commands are named PMBUS_VIRT_xxx and start with PMBUS_VIRT_BASE. All
++virtual commands are word sized.
++
++There are currently two types of virtual commands.
++
++- READ commands are read-only; writes are either ignored or return an error.
++- RESET commands are read/write. Reading reset registers returns zero
++  (used for detection), writing any value causes the associated history to be
++  reset.
++
++Virtual commands have to be handled in device specific driver code. Chip driver
++code returns non-negative values if a virtual command is supported, or a
++negative error code if not. The chip driver may return -ENODATA or any other
++Linux error code in this case, though an error code other than -ENODATA is
++handled more efficiently and thus preferred. Either case, the calling PMBus
++core code will abort if the chip driver returns an error code when reading
++or writing virtual registers (in other words, the PMBus core code will never
++send a virtual command to a chip).
++
++PMBus driver information
++------------------------
++
++PMBus driver information, defined in struct pmbus_driver_info, is the main means
++for device specific drivers to pass information to the core PMBus driver.
++Specifically, it provides the following information.
++
++- For devices supporting its data in Direct Data Format, it provides coefficients
++  for converting register values into normalized data. This data is usually
++  provided by chip manufacturers in device datasheets.
++- Supported chip functionality can be provided to the core driver. This may be
++  necessary for chips which react badly if non-supported commands are executed,
++  and/or to speed up device detection and initialization.
++- Several function entry points are provided to support overriding and/or
++  augmenting generic command execution. This functionality can be used to map
++  non-standard PMBus commands to standard commands, or to augment standard
++  command return values with device specific information.
++
++  API functions
++  -------------
++
++  Functions provided by chip driver
++  ---------------------------------
++
++  All functions return the command return value (read) or zero (write) if
++  successful. A return value of -ENODATA indicates that there is no manufacturer
++  specific command, but that a standard PMBus command may exist. Any other
++  negative return value indicates that the commands does not exist for this
++  chip, and that no attempt should be made to read or write the standard
++  command.
++
++  As mentioned above, an exception to this rule applies to virtual commands,
++  which  _must_ be handled in driver specific code. See "Virtual PMBus Commands"
++  above for more details.
++
++  Command execution in the core PMBus driver code is as follows.
++
++	if (chip_access_function) {
++		status = chip_access_function();
++		if (status != -ENODATA)
++			return status;
++	}
++	if (command >= PMBUS_VIRT_BASE)	/* For word commands/registers only */
++		return -EINVAL;
++	return generic_access();
++
++  Chip drivers may provide pointers to the following functions in struct
++  pmbus_driver_info. All functions are optional.
++
++  int (*read_byte_data)(struct i2c_client *client, int page, int reg);
++
++  Read byte from page <page>, register <reg>.
++  <page> may be -1, which means "current page".
++
++  int (*read_word_data)(struct i2c_client *client, int page, int reg);
++
++  Read word from page <page>, register <reg>.
++
++  int (*write_word_data)(struct i2c_client *client, int page, int reg,
++		         u16 word);
++
++  Write word to page <page>, register <reg>.
++
++  int (*write_byte)(struct i2c_client *client, int page, u8 value);
++
++  Write byte to page <page>, register <reg>.
++  <page> may be -1, which means "current page".
++
++  int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info);
++
++  Determine supported PMBus functionality. This function is only necessary
++  if a chip driver supports multiple chips, and the chip functionality is not
++  pre-determined. It is currently only used by the generic pmbus driver
++  (pmbus.c).
++
++  Functions exported by core driver
++  ---------------------------------
++
++  Chip drivers are expected to use the following functions to read or write
++  PMBus registers. Chip drivers may also use direct I2C commands. If direct I2C
++  commands are used, the chip driver code must not directly modify the current
++  page, since the selected page is cached in the core driver and the core driver
++  will assume that it is selected. Using pmbus_set_page() to select a new page
++  is mandatory.
++
++  int pmbus_set_page(struct i2c_client *client, u8 page);
++
++  Set PMBus page register to <page> for subsequent commands.
++
++  int pmbus_read_word_data(struct i2c_client *client, u8 page, u8 reg);
++
++  Read word data from <page>, <reg>. Similar to i2c_smbus_read_word_data(), but
++  selects page first.
++
++  int pmbus_write_word_data(struct i2c_client *client, u8 page, u8 reg,
++			    u16 word);
++
++  Write word data to <page>, <reg>. Similar to i2c_smbus_write_word_data(), but
++  selects page first.
++
++  int pmbus_read_byte_data(struct i2c_client *client, int page, u8 reg);
++
++  Read byte data from <page>, <reg>. Similar to i2c_smbus_read_byte_data(), but
++  selects page first. <page> may be -1, which means "current page".
++
++  int pmbus_write_byte(struct i2c_client *client, int page, u8 value);
++
++  Write byte data to <page>, <reg>. Similar to i2c_smbus_write_byte(), but
++  selects page first. <page> may be -1, which means "current page".
++
++  void pmbus_clear_faults(struct i2c_client *client);
++
++  Execute PMBus "Clear Fault" command on all chip pages.
++  This function calls the device specific write_byte function if defined.
++  Therefore, it must _not_ be called from that function.
++
++  bool pmbus_check_byte_register(struct i2c_client *client, int page, int reg);
++
++  Check if byte register exists. Return true if the register exists, false
++  otherwise.
++  This function calls the device specific write_byte function if defined to
++  obtain the chip status. Therefore, it must _not_ be called from that function.
++
++  bool pmbus_check_word_register(struct i2c_client *client, int page, int reg);
++
++  Check if word register exists. Return true if the register exists, false
++  otherwise.
++  This function calls the device specific write_byte function if defined to
++  obtain the chip status. Therefore, it must _not_ be called from that function.
++
++  int pmbus_do_probe(struct i2c_client *client, const struct i2c_device_id *id,
++                     struct pmbus_driver_info *info);
++
++  Execute probe function. Similar to standard probe function for other drivers,
++  with the pointer to struct pmbus_driver_info as additional argument. Calls
++  identify function if supported. Must only be called from device probe
++  function.
++
++  void pmbus_do_remove(struct i2c_client *client);
++
++  Execute driver remove function. Similar to standard driver remove function.
++
++  const struct pmbus_driver_info
++	*pmbus_get_driver_info(struct i2c_client *client);
++
++  Return pointer to struct pmbus_driver_info as passed to pmbus_do_probe().
++
++
++PMBus driver platform data
++==========================
++
++PMBus platform data is defined in include/linux/i2c/pmbus.h. Platform data
++currently only provides a flag field with a single bit used.
++
++#define PMBUS_SKIP_STATUS_CHECK (1 << 0)
++
++struct pmbus_platform_data {
++        u32 flags;              /* Device specific flags */
++};
++
++
++Flags
++-----
++
++PMBUS_SKIP_STATUS_CHECK
++
++During register detection, skip checking the status register for
++communication or command errors.
++
++Some PMBus chips respond with valid data when trying to read an unsupported
++register. For such chips, checking the status register is mandatory when
++trying to determine if a chip register exists or not.
++Other PMBus chips don't support the STATUS_CML register, or report
++communication errors for no explicable reason. For such chips, checking the
++status register must be disabled.
++
++Some i2c controllers do not support single-byte commands (write commands with
++no data, i2c_smbus_write_byte()). With such controllers, clearing the status
++register is impossible, and the PMBUS_SKIP_STATUS_CHECK flag must be set.

++ * -ENODATA or any other error code in this case, though an error code other

+Subject: [PATCH 001/130] [MTD] fix m25p80 64-bit divisions
+
+MTD has recently been upgraded for 64-bit support, see commit
+number 69423d99fc182a81f3c5db3eb5c140acc6fc64be in the
+mtd-2.6.git tree (git://git.infradead.org/mtd-2.6.git)
+or see this URL:
+http://git.infradead.org/mtd-2.6.git?a=commit;h=69423d99fc182a81f3c5db3eb5c140acc6fc64be
+
+Some variables in MTD data structures which were 32-bit
+became 64-bit. Namely, the 'size' field in 'struct mtd_info'
+and the 'addr'/'len' fields in 'struct erase_info'. This
+means we have to use 'do_div' to divide them.
+
+This patch fixes the following linking error:
+ERROR: "__umoddi3" [drivers/mtd/devices/m25p80.ko] undefined!
+
+This patch changes divisions of 64-bit variable so that they use
+'do_div'. This patch also change some print placeholders to
+get rid of gcc warnings.

+Subject: bzip2/lzma: library support for gzip, bzip2 and lzma decompression
+
+Impact: Replaces inflate.c with a wrapper around zlib_inflate; new library code
+
+This is the first part of the bzip2/lzma patch
+
+The bzip patch is based on an idea by Christian Ludwig, includes support for
+compressing the kernel with bzip2 or lzma rather than gzip. Both
+compressors give smaller sizes than gzip.  Lzma's decompresses faster
+than bzip2.
+
+It also supports ramdisks and initramfs' compressed using these two
+compressors.
+
+The functionality has been successfully used for a couple of years by
+the udpcast project
+
+This version applies to "tip" kernel 2.6.28
+
+This part contains:
+- changed inflate.c to accomodate rest of patch
+- implementation of bzip2 compression (not used at this stage yet)
+- implementation of lzma compression (not used at this stage yet)
+- Makefile routines to support bzip2 and lzma kernel compression

+Subject: bzip2/lzma: config and initramfs support for bzip2/lzma decompression
+
+Impact: New code for initramfs decompression, new features
+
+This is the second part of the bzip2/lzma patch
+
+The bzip patch is based on an idea by Christian Ludwig, includes support for
+compressing the kernel with bzip2 or lzma rather than gzip. Both
+compressors give smaller sizes than gzip.  Lzma's decompresses faster
+than bzip2.
+
+It also supports ramdisks and initramfs' compressed using these two
+compressors.
+
+The functionality has been successfully used for a couple of years by
+the udpcast project
+
+This version applies to "tip" kernel 2.6.28
+
+This part contains:
+- support for new compressions (bzip2 and lzma) in initramfs and
+old-style ramdisk
+- config dialog for kernel compression (but new kernel compressions
+not yet supported)

+Subject: [PATCH 05/16] mtd: Bug in m25p80.c during whole-chip erase
+
+There is a logic error in "whole chip erase" for the m25p80 family.  If
+the whole device is successfully erased, erase_chip() will return 0, and
+the code will fall through to the "else" clause, and do sector-by-sector
+erase in addition to the whole-chip erase.  This patch corrects that.
+
+Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected
+to a 400 MHz powerpc.  Increasing it allows me to successfully program
+the device on my board.

+
+Extend erase timeout in M25P80 SPI Flash driver.
+
+The M25P80 drivers fails erasing sectors on a M25P128 because the ready
+wait timeout is too short. Change the timeout from a simple loop count to a
+suitable number of seconds.

+The SST SPI flashes are a bit non-standard in that they can be programmed
+one byte at a time (including address!), or they can be written two bytes
+at a time with auto address incrementing (AAI).  The latter form is
+obviously much better for performance, so let's use it when possible.

+Subject: [PATCH 21/27] mtd: m25p80: Add support for CAT25xxx serial EEPROMs
+
+CAT25 chips (as manufactured by On Semiconductor, previously Catalyst
+Semiconductor) are similar to the original M25Px0 chips, except:
+
+- Address width can vary (1-2 bytes, in contrast to 3 bytes in M25P
+  chips). So, implement convenient m25p_addr2cmd() and m25p_cmdsz()
+  calls, and place address width information into flash_info struct;
+
+- Page size can vary, therefore we shouldn't hardcode it, so get rid
+  of FLASH_PAGESIZE definition, and place the page size information
+  into flash_info struct;
+
+- CAT25 EEPROMs don't need to be erased, so add NO_ERASE flag, and
+  propagate it to the mtd subsystem.

+Subject: [PATCH 26/27] mtd: m25p80: modify info for Micron N25Q128
+
+Micron N25Q128 has two types of flash:
+
+ - One is for 1.8v supply voltage, prefixed with "n25q128a11" and the jedec
+   code is 0x20bb18.
+
+ - Another is for 3v supply voltage, prefixed with "n25q128a13" and the jedec
+   code is 0x20ba18.
+
+So modify the original type info and add another type for Micron N25Q128.

+Subject: [PATCH] ipv6: Plug sk_buff leak in ipv6_rcv (net/ipv6/ip6_input.c)
+
+Commit 778d80be52699596bf70e0eb0761cf5e1e46088d
+(ipv6: Add disable_ipv6 sysctl to disable IPv6 operaion on specific interface)
+seems to have introduced a leak of sk_buff's for ipv6 traffic,
+at least in some configurations where idev is NULL, or when ipv6
+is disabled via sysctl.
+
+The problem is that if the first condition of the if-statement
+returns non-NULL, it returns an skb with only one reference,
+and when the other conditions apply, execution jumps to the "out"
+label, which does not call kfree_skb for it.
+
+To plug this leak, change to use the "drop" label instead.
+(this relies on it being ok to call kfree_skb on NULL)
+This also allows us to avoid calling rcu_read_unlock here,
+and removes the only user of the "out" label.
