+Hierarchical Cgroups
+====================
+- Currently none of the IO control policy supports hierarhical groups. But
+  cgroup interface does allow creation of hierarhical cgroups and internally
+  IO policies treat them as flat hierarchy.
+
+  So this patch will allow creation of cgroup hierarhcy but at the backend
+  everything will be treated as flat. So if somebody created a hierarchy like
+  as follows.
+
+			root
+			/  \
+		     test1 test2
+			|
+		     test3
+
+  CFQ and throttling will practically treat all groups at same level.
+
+				pivot
+			     /  |   \  \
+			root  test1 test2  test3
+
+  Down the line we can implement hierarchical accounting/control support
+  and also introduce a new cgroup file "use_hierarchy" which will control
+  whether cgroup hierarchy is viewed as flat or hierarchical by the policy..
+  This is how memory controller also has implemented the things.

+Kernel driver for the NXP Semiconductors PN544 Near Field
+Communication chip
+
+Author: Jari Vanhala
+Contact: Matti Aaltonen (matti.j.aaltonen at nokia.com)
+
+General
+-------
+
+The PN544 is an integrated transmission module for contactless
+communication. The driver goes under drives/nfc/ and is compiled as a
+module named "pn544". It registers a misc device and creates a device
+file named "/dev/pn544".
+
+Host Interfaces: I2C, SPI and HSU, this driver supports currently only I2C.
+
+The Interface
+-------------
+
+The driver offers a sysfs interface for a hardware test and an IOCTL
+interface for selecting between two operating modes. There are read,
+write and poll functions for transferring messages. The two operating
+modes are the normal (HCI) mode and the firmware update mode.
+
+PN544 is controlled by sending messages from the userspace to the
+chip. The main function of the driver is just to pass those messages
+without caring about the message content.
+
+
+Protocols
+---------
+
+In the normal (HCI) mode and in the firmware update mode read and
+write functions behave a bit differently because the message formats
+or the protocols are different.
+
+In the normal (HCI) mode the protocol used is derived from the ETSI
+HCI specification. The firmware is updated using a specific protocol,
+which is different from HCI.
+
+HCI messages consist of an eight bit header and the message body. The
+header contains the message length. Maximum size for an HCI message is
+33. In HCI mode sent messages are tested for a correct
+checksum. Firmware update messages have the length in the second (MSB)
+and third (LSB) bytes of the message. The maximum FW message length is
+1024 bytes.
+
+For the ETSI HCI specification see
+http://www.etsi.org/WebSite/Technologies/ProtocolSpecification.aspx
+
+The Hardware Test
+-----------------
+
+The idea of the test is that it can performed by reading from the
+corresponding sysfs file. The test is implemented in the board file
+and it should test that PN544 can be put into the firmware update
+mode. If the test is not implemented the sysfs file does not get
+created.
+
+Example:
+> cat /sys/module/pn544/drivers/i2c\:pn544/3-002b/nfc_test
+1
+
+Normal Operation
+----------------
+
+PN544 is powered up when the device file is opened, otherwise it's
+turned off. Only one instance can use the device at a time.
+
+Userspace applications control PN544 with HCI messages. The hardware
+sends an interrupt when data is available for reading. Data is
+physically read when the read function is called by a userspace
+application. Poll() checks the read interrupt state. Configuration and
+self testing are also done from the userspace using read and write.
+
+Example platform data:
+
+static int rx71_pn544_nfc_request_resources(struct i2c_client *client)
+{
+	/* Get and setup the HW resources for the device */
+}
+
+static void rx71_pn544_nfc_free_resources(void)
+{
+	/* Release the HW resources */
+}
+
+static void rx71_pn544_nfc_enable(int fw)
+{
+	/* Turn the device on */
+}
+
+static int rx71_pn544_nfc_test(void)
+{
+	/*
+	 * Put the device into the FW update mode
+	 * and then back to the normal mode.
+	 * Check the behavior and return one on success,
+	 * zero on failure.
+	 */
+}
+
+static void rx71_pn544_nfc_disable(void)
+{
+	/* turn the power off */
+}
+
+static struct pn544_nfc_platform_data rx71_nfc_data = {
+	.request_resources = rx71_pn544_nfc_request_resources,
+	.free_resources = rx71_pn544_nfc_free_resources,
+	.enable = rx71_pn544_nfc_enable,
+	.test = rx71_pn544_nfc_test,

+Generators
+----------
+
+Sometimes one needs to be able not only to catch PPS signals but to produce
+them also. For example, running a distributed simulation, which requires
+computers' clock to be synchronized very tightly. One way to do this is to
+invent some complicated hardware solutions but it may be neither necessary
+nor affordable. The cheap way is to load a PPS generator on one of the
+computers (master) and PPS clients on others (slaves), and use very simple
+cables to deliver signals using parallel ports, for example.

+
+Please note that parallel port interrupt occurs only on high->low transition,
+so it is used for PPS assert edge. PPS clear edge can be determined only
+using polling in the interrupt handler which actually can be done way more
+precisely because interrupt handling delays can be quite big and random. So
+current parport PPS generator implementation (pps_gen_parport module) is
+geared towards using the clear edge for time synchronization.
+
+Clear edge polling is done with disabled interrupts so it's better to select
+delay between assert and clear edge as small as possible to reduce system
+latencies. But if it is too small slave won't be able to capture clear edge
+transition. The default of 30us should be good enough in most situations.
+The delay can be selected using 'delay' pps_gen_parport module parameter.

+
+Description
+-----------
+
+Support is provided through the sysfs w1_slave file. Each opening and
+read sequence of w1_slave file initiates the read of counters and ram
+available in DS2423 pages 12 - 15.
+
+Result of each page is provided as an ASCII output where each counter
+value and associated ram buffer is outpputed to own line.
+
+Each lines will contain the values of 42 bytes read from the counter and
+memory page along the crc=YES or NO for indicating whether the read operation
+was successfull and CRC matched.
+If the operation was successfull, there is also in the end of each line
+a counter value expressed as an integer after c=
+
+Meaning of 42 bytes represented is following:
+ - 1 byte from ram page
+ - 4 bytes for the counter value
+ - 4 zero bytes
+ - 2 bytes for crc16 which was calculated from the data read since the previous crc bytes
+ - 31 remaining bytes from the ram page
+ - crc=YES/NO indicating whether read was ok and crc matched
+ - c=<int> current counter value
+

+XZ data compression in Linux
+============================
+
+Introduction
+
+    XZ is a general purpose data compression format with high compression
+    ratio and relatively fast decompression. The primary compression
+    algorithm (filter) is LZMA2. Additional filters can be used to improve
+    compression ratio even further. E.g. Branch/Call/Jump (BCJ) filters
+    improve compression ratio of executable data.
+
+    The XZ decompressor in Linux is called XZ Embedded. It supports
+    the LZMA2 filter and optionally also BCJ filters. CRC32 is supported
+    for integrity checking. The home page of XZ Embedded is at
+    <http://tukaani.org/xz/embedded.html>, where you can find the
+    latest version and also information about using the code outside
+    the Linux kernel.
+
+    For userspace, XZ Utils provide a zlib-like compression library
+    and a gzip-like command line tool. XZ Utils can be downloaded from
+    <http://tukaani.org/xz/>.
+
+XZ related components in the kernel
+
+    The xz_dec module provides XZ decompressor with single-call (buffer
+    to buffer) and multi-call (stateful) APIs. The usage of the xz_dec
+    module is documented in include/linux/xz.h.
+
+    The xz_dec_test module is for testing xz_dec. xz_dec_test is not
+    useful unless you are hacking the XZ decompressor. xz_dec_test
+    allocates a char device major dynamically to which one can write
+    .xz files from userspace. The decompressed output is thrown away.
+    Keep an eye on dmesg to see diagnostics printed by xz_dec_test.
+    See the xz_dec_test source code for the details.
+
+    For decompressing the kernel image, initramfs, and initrd, there
+    is a wrapper function in lib/decompress_unxz.c. Its API is the
+    same as in other decompress_*.c files, which is defined in
+    include/linux/decompress/generic.h.
+
+    scripts/xz_wrap.sh is a wrapper for the xz command line tool found
+    from XZ Utils. The wrapper sets compression options to values suitable
+    for compressing the kernel image.
+
+    For kernel makefiles, two commands are provided for use with
+    $(call if_needed). The kernel image should be compressed with
+    $(call if_needed,xzkern) which will use a BCJ filter and a big LZMA2
+    dictionary. It will also append a four-byte trailer containing the
+    uncompressed size of the file, which is needed by the boot code.
+    Other things should be compressed with $(call if_needed,xzmisc)
+    which will use no BCJ filter and 1 MiB LZMA2 dictionary.
+
+Notes on compression options
+
+    Since the XZ Embedded supports only streams with no integrity check or
+    CRC32, make sure that you don't use some other integrity check type
+    when encoding files that are supposed to be decoded by the kernel. With
+    liblzma, you need to use either LZMA_CHECK_NONE or LZMA_CHECK_CRC32
+    when encoding. With the xz command line tool, use --check=none or
+    --check=crc32.
+
+    Using CRC32 is strongly recommended unless there is some other layer
+    which will verify the integrity of the uncompressed data anyway.
+    Double checking the integrity would probably be waste of CPU cycles.
+    Note that the headers will always have a CRC32 which will be validated
+    by the decoder; you can only change the integrity check type (or
+    disable it) for the actual uncompressed data.
+
+    In userspace, LZMA2 is typically used with dictionary sizes of several
+    megabytes. The decoder needs to have the dictionary in RAM, thus big
+    dictionaries cannot be used for files that are intended to be decoded
+    by the kernel. 1 MiB is probably the maximum reasonable dictionary
+    size for in-kernel use (maybe more is OK for initramfs). The presets
+    in XZ Utils may not be optimal when creating files for the kernel,
+    so don't hesitate to use custom settings. Example:
+
+        xz --check=crc32 --lzma2=dict=512KiB inputfile
+
+    An exception to above dictionary size limitation is when the decoder
+    is used in single-call mode. Decompressing the kernel itself is an
+    example of this situation. In single-call mode, the memory usage
+    doesn't depend on the dictionary size, and it is perfectly fine to
+    use a big dictionary: for maximum compression, the dictionary should
+    be at least as big as the uncompressed data itself.
+
+Future plans
+
+    Creating a limited XZ encoder may be considered if people think it is
+    useful. LZMA2 is slower to compress than e.g. Deflate or LZO even at
+    the fastest settings, so it isn't clear if LZMA2 encoder is wanted
+    into the kernel.
+
+    Support for limited random-access reading is planned for the
+    decompression code. I don't know if it could have any use in the
+    kernel, but I know that it would be useful in some embedded projects
+    outside the Linux kernel.
+
+Conformance to the .xz file format specification
+
+    There are a couple of corner cases where things have been simplified
+    at expense of detecting errors as early as possible. These should not
+    matter in practice all, since they don't cause security issues. But
+    it is good to know this if testing the code e.g. with the test files
+    from XZ Utils.
+
+Reporting bugs
+
+    Before reporting a bug, please check that it's not fixed already
+    at upstream. See <http://tukaani.org/xz/embedded.html> to get the
+    latest code.
+
+    Report bugs to <lasse.collin@tukaani.org> or visit #tukaani on
+    Freenode and talk to Larhzu. I don't actively read LKML or other
+    kernel-related mailing lists, so if there's something I should know,
+    you should email to me personally or use IRC.
+
+    Don't bother Igor Pavlov with questions about the XZ implementation
+    in the kernel or about XZ Utils. While these two implementations
+    include essential code that is directly based on Igor Pavlov's code,
+    these implementations aren't maintained nor supported by him.

- * Values for the BitRate Register (SCBRR)

- * The values are actually divisors for a frequency which can
- * be internal to the SH3 (14.7456MHz) or derived from an external
- * clock source.  This driver assumes the internal clock is used;
- * to support using an external clock source, config options or

- *
- * Also, to support speeds below 2400 (why?) the lower 2 bits of

- *
- * Answer: The SCBRR register is only eight bits, and the value in
- * it gets larger with lower baud rates. At around 2400 (depending on
- * the peripherial module clock) you run out of bits. However the
- * lower two bits of SCSMR allow the module clock to be divided down,
- * scaling the value which is needed in SCBRR.

+This is an obsolete driver for some the CS5535 and CS5536 southbridge GPIOs.
+It has been replaced by a driver that makes use of the Linux GPIO subsystem.
+Please switch to that driver, and let dilinger@queued.net know if there's
+anything missing from the new driver.
+
+This driver is scheduled for removal in 2.6.40.

+ * Because the output buffer is used as the workspace, streams encoded using

+ * can be smaller than the dictionary size stored in the stream headers.

+ * may allocate once it has parsed the dictionary size from the stream
+ * headers. This way excessive allocations can be avoided while still
+ * limiting the maximum memory usage to a sane value to prevent running the
+ * system out of memory when decompressing streams from untrusted sources.

+ * Wrapper for decompressing XZ-compressed kernel, initramfs, and initrd

+ *
+ * This file has been put into the public domain.
+ * You can do whatever you want with this file.

+
+/*
+ * Important notes about in-place decompression
+ *
+ * At least on x86, the kernel is decompressed in place: the compressed data
+ * is placed to the end of the output buffer, and the decompressor overwrites
+ * most of the compressed data. There must be enough safety margin to
+ * guarantee that the write position is always behind the read position.
+ *
+ * The safety margin for XZ with LZMA2 or BCJ+LZMA2 is calculated below.
+ * Note that the margin with XZ is bigger than with Deflate (gzip)!
+ *
+ * The worst case for in-place decompression is that the beginning of
+ * the file is compressed extremely well, and the rest of the file is
+ * uncompressible. Thus, we must look for worst-case expansion when the
+ * compressor is encoding uncompressible data.
+ *
+ * The structure of the .xz file in case of a compresed kernel is as follows.
+ * Sizes (as bytes) of the fields are in parenthesis.
+ *
+ *    Stream Header (12)
+ *    Block Header:
+ *      Block Header (8-12)
+ *      Compressed Data (N)
+ *      Block Padding (0-3)
+ *      CRC32 (4)
+ *    Index (8-20)
+ *    Stream Footer (12)
+ *
+ * Normally there is exactly one Block, but let's assume that there are
+ * 2-4 Blocks just in case. Because Stream Header and also Block Header
+ * of the first Block don't make the decompressor produce any uncompressed
+ * data, we can ignore them from our calculations. Block Headers of possible
+ * additional Blocks have to be taken into account still. With these
+ * assumptions, it is safe to assume that the total header overhead is
+ * less than 128 bytes.
+ *
+ * Compressed Data contains LZMA2 or BCJ+LZMA2 encoded data. Since BCJ
+ * doesn't change the size of the data, it is enough to calculate the
+ * safety margin for LZMA2.
+ *
+ * LZMA2 stores the data in chunks. Each chunk has a header whose size is
+ * a maximum of 6 bytes, but to get round 2^n numbers, let's assume that
+ * the maximum chunk header size is 8 bytes. After the chunk header, there
+ * may be up to 64 KiB of actual payload in the chunk. Often the payload is
+ * quite a bit smaller though; to be safe, let's assume that an average
+ * chunk has only 32 KiB of payload.
+ *
+ * The maximum uncompressed size of the payload is 2 MiB. The minimum
+ * uncompressed size of the payload is in practice never less than the
+ * payload size itself. The LZMA2 format would allow uncompressed size
+ * to be less than the payload size, but no sane compressor creates such
+ * files. LZMA2 supports storing uncompressible data in uncompressed form,
+ * so there's never a need to create payloads whose uncompressed size is
+ * smaller than the compressed size.
+ *
+ * The assumption, that the uncompressed size of the payload is never
+ * smaller than the payload itself, is valid only when talking about
+ * the payload as a whole. It is possible that the payload has parts where
+ * the decompressor consumes more input than it produces output. Calculating
+ * the worst case for this would be tricky. Instead of trying to do that,
+ * let's simply make sure that the decompressor never overwrites any bytes
+ * of the payload which it is currently reading.
+ *
+ * Now we have enough information to calculate the safety margin. We need
+ *   - 128 bytes for the .xz file format headers;
+ *   - 8 bytes per every 32 KiB of uncompressed size (one LZMA2 chunk header
+ *     per chunk, each chunk having average payload size of 32 KiB); and
+ *   - 64 KiB (biggest possible LZMA2 chunk payload size) to make sure that
+ *     the decompressor never overwrites anything from the LZMA2 chunk
+ *     payload it is currently reading.
+ *
+ * We get the following formula:
+ *
+ *    safety_margin = 128 + uncompressed_size * 8 / 32768 + 65536
+ *                  = 128 + (uncompressed_size >> 12) + 65536
+ *
+ * For comparision, according to arch/x86/boot/compressed/misc.c, the
+ * equivalent formula for Deflate is this:
+ *
+ *    safety_margin = 18 + (uncompressed_size >> 12) + 32768
+ *
+ * Thus, when updating Deflate-only in-place kernel decompressor to
+ * support XZ, the fixed overhead has to be increased from 18+32768 bytes
+ * to 128+65536 bytes.
