i2c: i2c-st: Add ST I2C controller
This patch adds support to SSC (Synchronous Serial Controller) I2C driver. This IP also supports SPI protocol, but this is not the aim of this driver. This IP is embedded in all ST SoCs for Set-top box platorms, and supports I2C Standard and Fast modes.

fbdev changes for 3.13
Nothing particularly stands out in this pull request. The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons. There are also a few commits that have changes to arch/arm/mach-at91 and arch/avr32, which have been acked by the maintainers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJSg2oCAAoJEPo9qoy8lh71vXsP/2AjkzOlcKBPutMG/W30QMHT tkKfr/RL8C3oXcimkE6ch3ksbFj2t5corxa/DLTdESdTpeFAgxj72pcdhN3X4+Xs 7IokExM2W5s6p4pP66PTr2A5XhEyAHtEMp+2JbHPRzwZitblzBLZvuPUJljwJDpj Z9+sD00xv/MZrXDCsEN8k2xdJ3rFn6JgX267y1qajlsocZoseTF2ed94IN/YnIM7 B2hra1B4E21FPYLzRDOJRmZa0YGomLTymezPnPg33hLBhnJU/aG4HLDHKUZWhduz /6UwACH63ja7I2z/8AZHQ1ACdbGheRtHbjwV9LLYlbaAvPmUqNTZ4b6UeQOb/EZ0 3SPCYbwD6+RMhSx/j/XhySvw82RY0i1aTlTDyjgOggfrfdi4x1Wk54bUWp5l9O3D SX1vSpNLGSh4GKXRzJjf3jouG/LcOzlpDlVZXzgsPzkyirluUv6QdMTopJwFwIGx rFgtsbkvhEsFvaNhhVIqQXKfwZ69r42U5JC+fDM5u7VX0mqyJ1usUNGvNSeifcDg EwUAI6RGnOXCO6crj2BZYpRTdc61tnY9b4CGLHDCeQkEXokEsEJ7Mz+8YfSwFo7X wqh+dAPQaixeHtUFZ8GhHXeAsjoQRSBXygf3NSNmCeP3WsmuozbauuujSrrTHITp LOXFPhU9uxHu4mDd6wrq =59+j -----END PGP SIGNATURE----- Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux Pull fbdev changes from Tomi Valkeinen: "Nothing particularly stands out in this pull request.

A set of device-mapper changes for 3.13.
Improve reliability of buffer allocations for dm messages with a small
number of arguments, a couple path group initialization fixes for dm
multipath, a fix for resizing a dm array, various fixes and
optimizations for dm cache, a fix for device mapper's Kconfig menu
indentation.
Features added include:
- dm crypt support for activating legacy CBC TrueCrypt containers
(useful for forensics of these old TCRYPT containers)
- reduced dm-cache memory requirements for each block in the cache
- basic support for shrinking a dm-cache's cache (fast) device
- most notably, dm-cache support for managing cache coherency when
deploying dm-cache with sophisticated origin volumes (that support
hardware snapshots and/or clustering): these changes come in the form
of a new passthrough operation mode and a cache block invalidation
interface.

MTD merge for 3.13
* Unify some compile-time differences so that we have fewer uses of
#ifdef CONFIG_OF in atmel_nand
* Other general cleanups (removing unused functions, options, variables,
fields; use correct interfaces)
* Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via
ONFI
* Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.)
* Improve differentiation between SLC and MLC NAND -- this clarifies an ABI
issue regarding the MTD "type" (in sysfs and in ioctl(MEMGETINFO)), where
the MTD_MLCNANDFLASH type was present but inconsistently used
* Extend GPMI NAND to support multi-chip-select NAND for some platforms
* Many improvements to the OMAP2/3 NAND driver, including an expanded DT
binding to bring us closer to mainline support for some OMAP systems
* Fix a deadlock in the error path of the Atmel NAND driver probe
* Correct the error codes from MTD mmap() to conform to POSIX and the Linux
Programmer's Manual. This is an acknowledged change in the MTD ABI, but I
can't imagine somebody relying on the non-standard -ENOSYS error code
specifically. Am I just being unimaginative? :)
* Fix a few important GPMI NAND bugs (one regression from 3.12 and one
long-standing race condition)
* More? Read the log!

Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
"This series cleans up the handling of DMA masks in a lot of drivers,
fixing some bugs as we go.
Some of the more serious errors include:
- drivers which only set their coherent DMA mask if the attempt to
set the streaming mask fails.
- drivers which test for a NULL dma mask pointer, and then set the
dma mask pointer to a location in their module .data section -
which will cause problems if the module is reloaded.
To counter these, I have introduced two helper functions:
- dma_set_mask_and_coherent() takes care of setting both the
streaming and coherent masks at the same time, with the correct
error handling as specified by the API.
- dma_coerce_mask_and_coherent() which resolves the problem of
drivers forcefully setting DMA masks. This is more a marker for
future work to further clean these locations up - the code which
creates the devices really should be initialising these, but to fix
that in one go along with this change could potentially be very
disruptive.
The last thing this series does is prise away some of Linux's addition
to "DMA addresses are physical addresses and RAM always starts at
zero". We have ARM LPAE systems where all system memory is above 4GB
physical, hence having DMA masks interpreted by (eg) the block layers
as describing physical addresses in the range 0..DMAMASK fails on
these platforms. Santosh Shilimkar addresses this in this series; the
patches were copied to the appropriate people multiple times but were
ignored.
Fixing this also gets rid of some ARM weirdness in the setup of the
max*pfn variables, and brings ARM into line with every other Linux
architecture as far as those go"

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:
1) The addition of nftables. No longer will we need protocol aware
firewall filtering modules, it can all live in userspace.
At the core of nftables is a, for lack of a better term, virtual
machine that executes byte codes to inspect packet or metadata
(arriving interface index, etc.) and make verdict decisions.
Besides support for loading packet contents and comparing them, the
interpreter supports lookups in various datastructures as
fundamental operations. For example sets are supports, and
therefore one could create a set of whitelist IP address entries
which have ACCEPT verdicts attached to them, and use the appropriate
byte codes to do such lookups.
Since the interpreted code is composed in userspace, userspace can
do things like optimize things before giving it to the kernel.
Another major improvement is the capability of atomically updating
portions of the ruleset. In the existing netfilter implementation,
one has to update the entire rule set in order to make a change and
this is very expensive.
Userspace tools exist to create nftables rules using existing
netfilter rule sets, but both kernel implementations will need to
co-exist for quite some time as we transition from the old to the
new stuff.
Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have
worked so hard on this.
2) Daniel Borkmann and Hannes Frederic Sowa made several improvements
to our pseudo-random number generator, mostly used for things like
UDP port randomization and netfitler, amongst other things.
In particular the taus88 generater is updated to taus113, and test
cases are added.
3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet
and Yang Yingliang.
4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin
Sujir.
5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,
Neal Cardwell, and Yuchung Cheng.
6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary
control message data, much like other socket option attributes.
From Francesco Fusco.
7) Allow applications to specify a cap on the rate computed
automatically by the kernel for pacing flows, via a new
SO_MAX_PACING_RATE socket option. From Eric Dumazet.
8) Make the initial autotuned send buffer sizing in TCP more closely
reflect actual needs, from Eric Dumazet.
9) Currently early socket demux only happens for TCP sockets, but we
can do it for connected UDP sockets too. Implementation from Shawn
Bohrer.
10) Refactor inet socket demux with the goal of improving hash demux
performance for listening sockets. With the main goals being able
to use RCU lookups on even request sockets, and eliminating the
listening lock contention. From Eric Dumazet.
11) The bonding layer has many demuxes in it's fast path, and an RCU
conversion was started back in 3.11, several changes here extend the
RCU usage to even more locations. From Ding Tianhong and Wang
Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav
Falico.
12) Allow stackability of segmentation offloads to, in particular, allow
segmentation offloading over tunnels. From Eric Dumazet.
13) Significantly improve the handling of secret keys we input into the
various hash functions in the inet hashtables, TCP fast open, as
well as syncookies. From Hannes Frederic Sowa. The key fundamental
operation is "net_get_random_once()" which uses static keys.
Hannes even extended this to ipv4/ipv6 fragmentation handling and
our generic flow dissector.
14) The generic driver layer takes care now to set the driver data to
NULL on device removal, so it's no longer necessary for drivers to
explicitly set it to NULL any more. Many drivers have been cleaned
up in this way, from Jingoo Han.
15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.
16) Improve CRC32 interfaces and generic SKB checksum iterators so that
SCTP's checksumming can more cleanly be handled. Also from Daniel
Borkmann.
17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces
using the interface MTU value. This helps avoid PMTU attacks,
particularly on DNS servers. From Hannes Frederic Sowa.
18) Use generic XPS for transmit queue steering rather than internal
(re-)implementation in virtio-net. From Jason Wang.

Discussion at Kernel Summit made it clear that the presence or absence of specific Kconfig symbols are not considered ABI, and that no userspace (or bootloader, etc) should rely on them. In addition, kernel-internal symbols are well established as non-ABI, per Documentation/stable_api_nonsense.txt. Document both of these in Documentation/ABI/README, in a new section for notable bits of non-ABI.

backlight: lp855x_bl: support new LP8555 device
LP8555 is one of the LP855x family devices. This device needs pre_init_device() and post_init_device() driver structure. It's same as LP8557, so the device configuration code is shared with LP8557. Backlight outputs are generated from dual DC-DC boost converters. It's configurable EPROM settings which are defined in the platform data. Driver documentation and device tree bindings are updated.

vsprintf: check real user/group id for %pK
Some setuid binaries will allow reading of files which have read permission by the real user id. This is problematic with files which use %pK because the file access permission is checked at open() time, but the kptr_restrict setting is checked at read() time. If a setuid binary opens a %pK file as an unprivileged user, and then elevates permissions before reading the file, then kernel pointer values may be leaked. This happens for example with the setuid pppd application on Ubuntu 12.04: $ head -1 /proc/kallsyms 00000000 T startup_32 $ pppd file /proc/kallsyms pppd: In file /proc/kallsyms: unrecognized option 'c1000000' This will only leak the pointer value from the first line, but other setuid binaries may leak more information. Fix this by adding a check that in addition to the current process having CAP_SYSLOG, that effective user and group ids are equal to the real ids. If a setuid binary reads the contents of a file which uses %pK then the pointer values will be printed as NULL if the real user is unprivileged. Update the sysctl documentation to reflect the changes, and also correct the documentation to state the kptr_restrict=0 is the default. This is a only temporary solution to the issue. The correct solution is to do the permission check at open() time on files, and to replace %pK with a function which checks the open() time permission. %pK uses in printk should be removed since no sane permission check can be done, and instead protected by using dmesg_restrict.

drivers/char/hpet.c: allow user controlled mmap for user processes
The CONFIG_HPET_MMAP Kconfig option exposes the memory map of the HPET registers to userspace. The Kconfig help points out that in some cases this can be a security risk as some systems may erroneously configure the map such that additional data is exposed to userspace. This is a problem for distributions -- some users want the MMAP functionality but it comes with a significant security risk. In an effort to mitigate this risk, and due to the low number of users of the MMAP functionality, I've introduced a kernel parameter, hpet_mmap_enable, that is required in order to actually have the HPET MMAP exposed.

mm: improve the description for dirty_background_ratio/dirty_ratio sysctl
Now dirty_background_ratio/dirty_ratio contains a percentage of total avaiable memory, which contains free pages and reclaimable pages. The number of these pages is not equal to the number of total system memory. But they are described as a percentage of total system memory in Documentation/sysctl/vm.txt.

mem-hotplug: introduce movable_node boot option
The hot-Pluggable field in SRAT specifies which memory is hotpluggable. As we mentioned before, if hotpluggable memory is used by the kernel, it cannot be hot-removed. So memory hotplug users may want to set all hotpluggable memory in ZONE_MOVABLE so that the kernel won't use it. Memory hotplug users may also set a node as movable node, which has ZONE_MOVABLE only, so that the whole node can be hot-removed. But the kernel cannot use memory in ZONE_MOVABLE. By doing this, the kernel cannot use memory in movable nodes. This will cause NUMA performance down. And other users may be unhappy. So we need a way to allow users to enable and disable this functionality. In this patch, we introduce movable_node boot option to allow users to choose to not to consume hotpluggable memory at early boot time and later we can set it as ZONE_MOVABLE. To achieve this, the movable_node boot option will control the memblock allocation direction. That said, after memblock is ready, before SRAT is parsed, we should allocate memory near the kernel image as we explained in the previous patches. So if movable_node boot option is set, the kernel does the following: 1. After memblock is ready, make memblock allocate memory bottom up. 2. After SRAT is parsed, make memblock behave as default, allocate memory top down. Users can specify "movable_node" in kernel commandline to enable this functionality. For those who don't use memory hotplug or who don't want to lose their NUMA performance, just don't specify anything. The kernel will work as before.

memcg: support hierarchical memory.numa_stats
The memory.numa_stat file was not hierarchical. Memory charged to the children was not shown in parent's numa_stat. This change adds the "hierarchical_" stats to the existing stats. The new hierarchical stats include the sum of all children's values in addition to the value of the memcg. Tested: Create cgroup a, a/b and run workload under b. The values of b are included in the "hierarchical_*" under a. $ cd /sys/fs/cgroup $ echo 1 > memory.use_hierarchy $ mkdir a a/b Run workload in a/b: $ (echo $BASHPID >> a/b/cgroup.procs && cat /some/file && bash) & The hierarchical_ fields in parent (a) show use of workload in a/b: $ cat a/memory.numa_stat total=0 N0=0 N1=0 N2=0 N3=0 file=0 N0=0 N1=0 N2=0 N3=0 anon=0 N0=0 N1=0 N2=0 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 $ cat a/b/memory.numa_stat total=908 N0=552 N1=317 N2=39 N3=0 file=850 N0=549 N1=301 N2=0 N3=0 anon=58 N0=3 N1=16 N2=39 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 Signed-off-by: Ying Han <yinghan@google.com> Signed-off-by: Greg Thelen <gthelen@google.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

GPIO bulk changes for the v3.13 development cycle
- Merged the GPIO descriptor API from Alexandre Courbot.
This is a first step toward trying to get rid of the
global GPIO numberspace for the future.
- Add an API so that driver can flag that a certain GPIO
line is being used by a irqchip backend for generating
IRQs, so that we can enforce checks, like not allowing
users to switch that line to an output at runtime, since
this makes no sense. Implemented corresponding calls
in a few select drivers.
- ACPI GPIO cleanups, refactorings and switch to using the
descriptor-based interface.
- Support for the TPS80036 Palmas GPIO variant.
- A new driver for the Broadcom Kona GPIO SoC IP block.
- Device tree support for the PCF857x driver.
- A set of ARM GPIO refactorings with the goal of getting
rid of a bunch of custom GPIO implementations from the
arch/arm/* tree:
- Move the IOP GPIO driver to the GPIO subsystem and
fix all users to use the gpiolib API for accessing
GPIOs. Delete the old custom GPIO implementation.
- Delete the unused custom PXA GPIO implemention.
- Convert all users of the IXP4 custom GPIO
implementation to use gpiolib and delete the custom
implementation.
- Delete the custom Gemini GPIO implementation, also
completely unused.
- Various cleanups and renamings.

Main pin control pull request for the v3.13 cycle:
- Blackfin ADI pin control driver, we move yet another
architecture under this subsystem umbrella.
- Incremental updates to the Renesas Super-H PFC pin control
driver. New subdriver for the r8a7791 SoC.
- Non-linear GPIO ranges from the gpiolib side of things,
this enabled simplified device tree bindings by referring
entire groups of pins on some pin controller to act as
back-end for a certain GPIO-chip driver.
- Add the Abilis TB10x pin control driver used on the ARC
architecture. Also the corresponding GPIO driver is merged
through this tree, so the ARC has full support for pins
and GPIOs after this.
- Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin
controller instances. The i.MX1 and i.MX27 is an entirely
new family (silicon) of controllers whereas i.MX50 is
a variant of the previous supported controller.
- Then the usual slew of fixes, cleanups and incremental
updates.

Pull pin control updates from Linus Walleij:
"Main pin control pull request for the v3.13 cycle.
The changes hitting arch/blackfin are ACKed by the Blackfin
maintainer, and the device tree bindings are ACKed to the extent
possible by someone from the device tree maintainers group.
- Blackfin ADI pin control driver, we move yet another architecture
under this subsystem umbrella.
- Incremental updates to the Renesas Super-H PFC pin control driver.
New subdriver for the r8a7791 SoC.

The ARC DT changes are apparently still pending, that hopefully gets
sorted out in a timely manner.

sound updates for 3.13-rc1
There are no too intrusive changes in this update batch. The biggest
LOC is found in the new DICE driver, and other small changes are
scattered over the whole sound subtree (which is a common pattern).
Below are highlights:
- ALSA core:
* Memory allocation support with genpool
* Fix blocking in drain ioctl of compress_offload
- HD-audio:
* Improved AMD HDMI supports
* Intel HDMI detection improvements
* thinkpad_acpi mute-key integration
* New PCI ID, New ALC255,285,293 codecs, CX20952
- USB-audio:
* New buffer size management
* Clean up endpoint handling codes
- ASoC:
* Further work on the dmaengine helpers, including support for
configuring the parameters for DMA by reading the capabilities of
the DMA controller which removes some guesswork and magic numbers
from drivers.
* A refresh of the documentation.
* Conversions of many drivers to direct regmap API usage in order to
allow the ASoC level register I/O code to be removed, this will
hopefully be completed by v3.14.
* Support for using async register I/O in DAPM, reducing the time
taken to implement power transitions on systems that support it.
- Fireiwre: DICE driver
- Lots of small fixes for bugs reported by Coverity

spi: Updates for v3.13
As well as the usual driver updates and cleanups there's a few
improvements to the core here:
- The start of some improvements to factor out more of the SPI message
loop into the core. Right now this is just simplifying the code a
bit but hopefully next time around we'll also have managed to roll
out some noticable performance improvements which drivers can take
advantage of.
- Support for loading modules for ACPI enumerated SPI devices.
- Managed registration for SPI controllers.
- Helper for another common I/O pattern.

regulator: Updates for v3.13
Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that one
must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators.

dm cache: add cache block invalidation support
Cache block invalidation is removing an entry from the cache without writing it back. Cache blocks can be invalidated via the 'invalidate_cblocks' message, which takes an arbitrary number of cblock ranges: invalidate_cblocks [<cblock>|<cblock begin>-<cblock end>]* E.g. dmsetup message my_cache 0 invalidate_cblocks 2345 3456-4567 5678-6789 Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

dm cache: add passthrough mode
"Passthrough" is a dm-cache operating mode (like writethrough or writeback) which is intended to be used when the cache contents are not known to be coherent with the origin device. It behaves as follows: * All reads are served from the origin device (all reads miss the cache) * All writes are forwarded to the origin device; additionally, write hits cause cache block invalidates This mode decouples cache coherency checks from cache device creation, largely to avoid having to perform coherency checks while booting. Boot scripts can create cache devices in passthrough mode and put them into service (mount cached filesystems, for example) without having to worry about coherency. Coherency that exists is maintained, although the cache will gradually cool as writes take place. Later, applications can perform coherency checks, the nature of which will depend on the type of the underlying storage. If coherency can be verified, the cache device can be transitioned to writethrough or writeback mode while still warm; otherwise, the cache contents can be discarded prior to transitioning to the desired operating mode.

ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
the device tree source files in the kernel (arch/arm/boot/dts). Besides
that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board files
for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
- Some updates to pinctrl and other subsystems. Most of these are for
DT-enablement of the various platforms and acks have been collected.

ARM: driver updates for 3.13
Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree. In this case it's involved:
- Some Davinci driver updates that has required corresponding platform code
changes (gpio mostly)
- CCI bindings and a few driver updates
- Marvell mvebu patches for PCI MSI support (could have gone through the PCI
tree for this release, but they were acked by Bjorn for 3.12 so we kept them
through arm-soc).
- Marvell dove switch-over to DT-based PCIe configuration
- Misc updates for Samsung platform dmaengine drivers

Input: ti_am335x_tsc - fix spelling mistake in TSC/ADC DT binding
There was a spelling mistake on TSC/ADC binding where "coordinate" was spelled as "coordiante". We can't simply fix the error due to DT being an ABI, the approach taken was to first use correct spelling and if that fails, fall back to miss-spelled version. It's unfortunate that has creeped into the tree. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> |

ARM: SoC platform changes for 3.13
New and updated SoC support. Among the things new for this release are:
- More support for the AM33xx platforms from TI
- Tegra 124 support, and some updates to older tegra families as well
- imx cleanups and updates across the board
- A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
- A whole bunch of updates and fixes for integrator, making the platform code
more modern and switches over to DT-only booting.
- Support for two new Renesas shmobile chipsets. Next up for them is more work
on consolidation instead of introduction of new non-multiplatform SoCs, we're
all looking forward to that!
- Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

dm cache policy mq: implement writeback_work() and mq_{set,clear}_dirty()
There are now two multiqueues for in cache blocks. A clean one and a dirty one. writeback_work comes from the dirty one. Demotions come from the clean one. There are two benefits: - Performance improvement, since demoting a clean block is a noop. - The cache cleans itself when io load is light.

dm crypt: add TCW IV mode for old CBC TCRYPT containers
dm-crypt can already activate TCRYPT (TrueCrypt compatible) containers in LRW or XTS block encryption mode. TCRYPT containers prior to version 4.1 use CBC mode with some additional tweaks, this patch adds support for these containers. This new mode is implemented using special IV generator named TCW (TrueCrypt IV with whitening). TCW IV only supports containers that are encrypted with one cipher (Tested with AES, Twofish, Serpent, CAST5 and TripleDES). While this mode is legacy and is known to be vulnerable to some watermarking attacks (e.g. revealing of hidden disk existence) it can still be useful to activate old containers without using 3rd party software or for independent forensic analysis of such containers. (Both the userspace and kernel code is an independent implementation based on the format documentation and it completely avoids use of original source code.) The TCW IV generator uses two additional keys: Kw (whitening seed, size is always 16 bytes - TCW_WHITENING_SIZE) and Kiv (IV seed, size is always the IV size of the selected cipher). These keys are concatenated at the end of the main encryption key provided in mapping table. While whitening is completely independent from IV, it is implemented inside IV generator for simplification. The whitening value is always 16 bytes long and is calculated per sector from provided Kw as initial seed, xored with sector number and mixed with CRC32 algorithm. Resulting value is xored with ciphertext sector content. IV is calculated from the provided Kiv as initial IV seed and xored with sector number. Detailed calculation can be found in the Truecrypt documentation for version < 4.1 and will also be described on dm-crypt site, see: http://code.google.com/p/cryptsetup/wiki/DMCrypt The experimental support for activation of these containers is already present in git devel brach of cryptsetup.

vfs: take i_mutex on renamed file
A read delegation is used by NFSv4 as a guarantee that a client can perform local read opens without informing the server. The open operation takes the last component of the pathname as an argument, thus is also a lookup operation, and giving the client the above guarantee means informing the client before we allow anything that would change the set of names pointing to the inode. Therefore, we need to break delegations on rename, link, and unlink. We also need to prevent new delegations from being acquired while one of these operations is in progress. We could add some completely new locking for that purpose, but it's simpler to use the i_mutex, since that's already taken by all the operations we care about. The single exception is rename. So, modify rename to take the i_mutex on the file that is being renamed. Also fix up lockdep and Documentation/filesystems/directory-locking to reflect the change.

We also merge, and then revert, the ktap code, as Ingo and the other

Also in here are some kobject updates, devres expansions, and the first round of Tejun's sysfs reworking to enable it to be used by other subsystems as a backend for an in-kernel filesystem. All of these have been in linux-next for a while with no reported issues.

tcp: properly handle stretch acks in slow start
Slow start now increases cwnd by 1 if an ACK acknowledges some packets, regardless the number of packets. Consequently slow start performance is highly dependent on the degree of the stretch ACKs caused by receiver or network ACK compression mechanisms (e.g., delayed-ACK, GRO, etc). But slow start algorithm is to send twice the amount of packets of packets left so it should process a stretch ACK of degree N as if N ACKs of degree 1, then exits when cwnd exceeds ssthresh. A follow up patch will use the remainder of the N (if greater than 1) to adjust cwnd in the congestion avoidance phase. In addition this patch retires the experimental limited slow start (LSS) feature. LSS has multiple drawbacks but questionable benefit. The fractional cwnd increase in LSS requires a loop in slow start even though it's rarely used. Configuring such an increase step via a global sysctl on different BDPS seems hard. Finally and most importantly the slow start overshoot concern is now better covered by the Hybrid slow start (hystart) enabled by default.

Conflicts:
drivers/net/ethernet/emulex/benet/be.h
drivers/net/netconsole.c
net/bridge/br_private.h
Three mostly trivial conflicts.
The net/bridge/br_private.h conflict was a function signature (argument
addition) change overlapping with the extern removals from Joe Perches.
In drivers/net/netconsole.c we had one change adjusting a printk message
whilst another changed "printk(KERN_INFO" into "pr_info(".
Lastly, the emulex change was a new inline function addition overlapping
with Joe Perches's extern removals.
