+Subject: [PATCH v2] mtd: m25p80: Add support for ESMT F25L32PA
+
+This flashchip is used in D-Link DIR-610 A1 router board 
+and maybe several others, yet is not kernel upstream.
+
+So add support for it according to datasheet [0], making it easier
+to support other boards using this flashchip in the future.
+
+Changelog v2:
+ - Better description
+ - Datasheet link at the bottom, similar to other patches.

+Subject: [PATCH] MIPS: decompressor: fix build failure on memcpy() in
+ decompress.c
+
+The decompress.c file includes linux/kernel.h which causes the following
+inclusion chain to be pulled:
+linux/kernel.h ->
+	linux/dynamic_debug.h ->
+		linux/string.h ->
+			asm/string.h
+
+We end up having a the GCC builtin + architecture specific memcpy() expanding
+into this:
+
+void *({ size_t __len = (size_t n); void *__ret; if
+(__builtin_constant_p(size_t n) && __len >= 64) __ret = memcpy((void *dest),
+(const void *src), __len); else __ret = __builtin_memcpy((void *dest), (const
+void *src), __len); __ret; })
+{
+ [memcpy implementation in decompress.c starts here]
+ int i;
+ const char *s = src;
+ char *d = dest;
+
+ for (i = 0; i < n; i++)
+  d[i] = s[i];
+ return dest;
+}
+
+raising the following compilation error:
+arch/mips/boot/compressed/decompress.c:46:8: error: expected identifier or '('
+before '{' token
+
+There are at least three possibilities to fix this issue:
+
+1) define _LINUX_STRING_H_ at the beginning of decompress.c to prevent
+   further linux/string.h definitions and declarations from being used, and add
+   an explicit strstr() declaration for linux/dynamic_debug.h
+
+2) remove the inclusion of linux/kernel.h because we actually use no definition
+   or declaration from this header file
+
+3) undefine memcpy or re-define memcpy to memcpy thus resulting in picking up
+   the local memcpy() implementation to this compilation unit
+
+This patch uses the second option which is the less intrusive one.

++Overlay Filesystem
++==================
++
++This document describes a prototype for a new approach to providing
++overlay-filesystem functionality in Linux (sometimes referred to as
++union-filesystems).  An overlay-filesystem tries to present a
++filesystem which is the result over overlaying one filesystem on top
++of the other.
++
++The result will inevitably fail to look exactly like a normal
++filesystem for various technical reasons.  The expectation is that
++many use cases will be able to ignore these differences.
++
++This approach is 'hybrid' because the objects that appear in the
++filesystem do not all appear to belong to that filesystem.  In many
++cases an object accessed in the union will be indistinguishable
++from accessing the corresponding object from the original filesystem.
++This is most obvious from the 'st_dev' field returned by stat(2).
++
++While directories will report an st_dev from the overlay-filesystem,
++all non-directory objects will report an st_dev from the lower or
++upper filesystem that is providing the object.  Similarly st_ino will
++only be unique when combined with st_dev, and both of these can change
++over the lifetime of a non-directory object.  Many applications and
++tools ignore these values and will not be affected.
++
++Upper and Lower
++---------------
++
++An overlay filesystem combines two filesystems - an 'upper' filesystem
++and a 'lower' filesystem.  When a name exists in both filesystems, the
++object in the 'upper' filesystem is visible while the object in the
++'lower' filesystem is either hidden or, in the case of directories,
++merged with the 'upper' object.
++
++It would be more correct to refer to an upper and lower 'directory
++tree' rather than 'filesystem' as it is quite possible for both
++directory trees to be in the same filesystem and there is no
++requirement that the root of a filesystem be given for either upper or
++lower.
++
++The lower filesystem can be any filesystem supported by Linux and does
++not need to be writable.  The lower filesystem can even be another
++overlayfs.  The upper filesystem will normally be writable and if it
++is it must support the creation of trusted.* extended attributes, and
++must provide valid d_type in readdir responses, at least for symbolic
++links - so NFS is not suitable.
++
++A read-only overlay of two read-only filesystems may use any
++filesystem type.
++
++Directories
++-----------
++
++Overlaying mainly involves directories.  If a given name appears in both
++upper and lower filesystems and refers to a non-directory in either,
++then the lower object is hidden - the name refers only to the upper
++object.
++
++Where both upper and lower objects are directories, a merged directory
++is formed.
++
++At mount time, the two directories given as mount options are combined
++into a merged directory:
++
++  mount -t overlayfs overlayfs -olowerdir=/lower,upperdir=/upper /overlay
++
++Then whenever a lookup is requested in such a merged directory, the
++lookup is performed in each actual directory and the combined result
++is cached in the dentry belonging to the overlay filesystem.  If both
++actual lookups find directories, both are stored and a merged
++directory is created, otherwise only one is stored: the upper if it
++exists, else the lower.
++
++Only the lists of names from directories are merged.  Other content
++such as metadata and extended attributes are reported for the upper
++directory only.  These attributes of the lower directory are hidden.
++
++whiteouts and opaque directories
++--------------------------------
++
++In order to support rm and rmdir without changing the lower
++filesystem, an overlay filesystem needs to record in the upper filesystem
++that files have been removed.  This is done using whiteouts and opaque
++directories (non-directories are always opaque).
++
++The overlay filesystem uses extended attributes with a
++"trusted.overlay."  prefix to record these details.
++
++A whiteout is created as a symbolic link with target
++"(overlay-whiteout)" and with xattr "trusted.overlay.whiteout" set to "y".
++When a whiteout is found in the upper level of a merged directory, any
++matching name in the lower level is ignored, and the whiteout itself
++is also hidden.
++
++A directory is made opaque by setting the xattr "trusted.overlay.opaque"
++to "y".  Where the upper filesystem contains an opaque directory, any
++directory in the lower filesystem with the same name is ignored.
++
++readdir
++-------
++
++When a 'readdir' request is made on a merged directory, the upper and
++lower directories are each read and the name lists merged in the
++obvious way (upper is read first, then lower - entries that already
++exist are not re-added).  This merged name list is cached in the
++'struct file' and so remains as long as the file is kept open.  If the
++directory is opened and read by two processes at the same time, they
++will each have separate caches.  A seekdir to the start of the
++directory (offset 0) followed by a readdir will cause the cache to be
++discarded and rebuilt.
++
++This means that changes to the merged directory do not appear while a
++directory is being read.  This is unlikely to be noticed by many
++programs.
++
++seek offsets are assigned sequentially when the directories are read.
++Thus if
++  - read part of a directory
++  - remember an offset, and close the directory
++  - re-open the directory some time later
++  - seek to the remembered offset
++
++there may be little correlation between the old and new locations in
++the list of filenames, particularly if anything has changed in the
++directory.
++
++Readdir on directories that are not merged is simply handled by the
++underlying directory (upper or lower).
++
++
++Non-directories
++---------------
++
++Objects that are not directories (files, symlinks, device-special
++files etc.) are presented either from the upper or lower filesystem as
++appropriate.  When a file in the lower filesystem is accessed in a way
++the requires write-access, such as opening for write access, changing
++some metadata etc., the file is first copied from the lower filesystem
++to the upper filesystem (copy_up).  Note that creating a hard-link
++also requires copy_up, though of course creation of a symlink does
++not.
++
++The copy_up may turn out to be unnecessary, for example if the file is
++opened for read-write but the data is not modified.
++
++The copy_up process first makes sure that the containing directory
++exists in the upper filesystem - creating it and any parents as
++necessary.  It then creates the object with the same metadata (owner,
++mode, mtime, symlink-target etc.) and then if the object is a file, the
++data is copied from the lower to the upper filesystem.  Finally any
++extended attributes are copied up.
++
++Once the copy_up is complete, the overlay filesystem simply
++provides direct access to the newly created file in the upper
++filesystem - future operations on the file are barely noticed by the
++overlay filesystem (though an operation on the name of the file such as
++rename or unlink will of course be noticed and handled).
++
++
++Non-standard behavior
++---------------------
++
++The copy_up operation essentially creates a new, identical file and
++moves it over to the old name.  The new file may be on a different
++filesystem, so both st_dev and st_ino of the file may change.
++
++Any open files referring to this inode will access the old data and
++metadata.  Similarly any file locks obtained before copy_up will not
++apply to the copied up file.
++
++On a file opened with O_RDONLY fchmod(2), fchown(2), futimesat(2) and
++fsetxattr(2) will fail with EROFS.
++
++If a file with multiple hard links is copied up, then this will
++"break" the link.  Changes will not be propagated to other names
++referring to the same inode.
++
++Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory
++object in overlayfs will not contain valid absolute paths, only
++relative paths leading up to the filesystem's root.  This will be
++fixed in the future.
++
++Some operations are not atomic, for example a crash during copy_up or
++rename will leave the filesystem in an inconsistent state.  This will
++be addressed in the future.
++
++Changes to underlying filesystems
++---------------------------------
++
++Offline changes, when the overlay is not mounted, are allowed to either
++the upper or the lower trees.
++
++Changes to the underlying filesystems while part of a mounted overlay
++filesystem are not allowed.  If the underlying filesystem is changed,
++the behavior of the overlay is undefined, though it will not result in
++a crash or deadlock.

++	  An overlay filesystem combines two filesystems - an 'upper' filesystem
++	  and a 'lower' filesystem.  When a name exists in both filesystems, the
++	  object in the 'upper' filesystem is visible while the object in the
++	  'lower' filesystem is either hidden or, in the case of directories,
++	  merged with the 'upper' object.

+Subject: [PATCH 11/12] USB: EHCI: add ignore_oc flag to disable overcurrent
+ checking
+
+This patch adds an ignore_oc flag which can be set by EHCI controller
+not supporting or wanting to disable overcurrent checking. The EHCI
+platform data in include/linux/usb/ehci_pdriver.h is also augmented to
+take advantage of this new flag.

+From: Stephen Hemminger <stephen@networkplumber.org>
+Subject: bridge: allow receiption on disabled port
+
+When an ethernet device is enslaved to a bridge, and the bridge STP
+detects loss of carrier (or operational state down), then normally
+packet receiption is blocked.
+
+This breaks control applications like WPA which maybe expecting to
+receive packets to negotiate to bring link up. The bridge needs to
+block forwarding packets from these disabled ports, but there is no
+hard requirement to not allow local packet delivery.

+Subject: [PATCH] MIPS: improve checks for noncoherent DMA
+
+Only one MIPS development board actually supports enabling/disabling DMA
+coherency at runtime, so it's not a good idea to push the overhead of
+checking that configuration setting onto every other supported target as
+well.

+
+commit 73c54aa8c1de3f61a4c211cd47431293a6092f18 upstream.
+
+Mutex is faster and init_MUTEX has been deprecated, so we'll just switch
+to mutexes.

+ llseek
+
+commit ed8188fb7659cfb65b5adbe154d143190ade0324 upstream.
+
+There was not much point in having the yaffs version as it is
+functionally equivalent to the kernel one.
+
+This also gets rid of using BKL in yaffs2.

++ * that regcomp() supplies a regmust only if the r.e. contains something

++ * Structure for regexp "program".  This is essentially a linear encoding
++ * of a nondeterministic finite-state machine (aka syntax charts or
++ * "railroad normal form" in parsing technology).  Each node is an opcode
++ * plus a "next" pointer, possibly plus an operand.  "Next" pointers of
++ * all nodes except BRANCH implement concatenation; a "next" pointer with
++ * a BRANCH on both ends of it is connecting two alternatives.  (Here we
++ * have one of the subtle syntax dependencies:  an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.)  The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM.  In
++ * particular, the operand of a BRANCH node is the first node of the branch.
++ * (NB this is *not* a tree structure:  the tail of the branch connects
++ * to the thing following the set of BRANCHes.)  The opcodes are:

++
++	  ESFQ also adds control of the hash function used to identify packet

+Subject: [PATCH 3/7] skb_reduce_truesize: helper function for shrinking skbs
+ whenever needed
+
+On embedded devices in particular, large queues of small packets from the rx
+path with a large truesize can exist. Reducing their size can reduce
+memory pressure. skb_reduce_truesize is a helper function for doing this,
+when needed.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++	pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++	err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++	err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++	mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in			= The SPI data-IN GPIO pin number.
++gpio_data_out			= The SPI data-OUT GPIO pin number.
++gpio_clock			= The SPI Clock GPIO pin number.
++gpio_chipselect			= The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow	= Boolean. If 0, Chipselect is active-HIGH.
++				  If 1, Chipselect is active-LOW.
++spi_mode			= The SPI data mode. Can be 0-3.
++spi_delay			= Enable all delays in the lowlevel bitbanging.
++max_bus_speed			= The maximum SPI bus speed. In Hertz.
++
++register			= Not a configuration parameter.
++				  Used to register the configured card
++				  with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow	= 1		(CS active-LOW)
++spi_mode			= 0		(SPI_MODE_0)
++spi_delay			= 1		(enabled)
++max_bus_speed			= 5000000	(5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.
