Christoph Hellwig 1d0fd57a50 logfs: remove from tree
Logfs was introduced to the kernel in 2009, and hasn't seen any non
drive-by changes since 2012, while having lots of unsolved issues
including the complete lack of error handling, with more and more
issues popping up without any fixes.

The logfs.org domain has been bouncing from a mail, and the maintainer
on the non-logfs.org domain hasn't repsonded to past queries either.

Linus Torvalds e3842cbfe0 dmaengine updates for 4.10-rc1
Fairly routine update this time around with all changes specific to drivers.
 
  o New driver for STMicroelectronics FDMA
  o Memory-to-memory transfers on dw dmac
  o Support for slave maps on pl08x devices
  o Bunch of driver fixes to use dma_pool_zalloc
  o Bunch of compile and warning fixes spread across drivers

Linus Torvalds a57cb1c1d7 Merge branch 'akpm' (patches from Andrew)
Merge more updates from Andrew Morton:

 - a few misc things

 - kexec updates

 - DMA-mapping updates to better support networking DMA operations

 - IPC updates

 - various MM changes to improve DAX fault handling

 - lots of radix-tree changes, mainly to the test suite. All leading up
   to reimplementing the IDA/IDR code to be a wrapper layer over the
   radix-tree. However the final trigger-pulling patch is held off for
   4.11.

Linus Torvalds 852d21ae1f docs: add back 'Documentation/Changes' file (as symlink)
Jaegeuk Kim reports that the debian kernel package build gets confused
by the lack of Documentation/Changes file.  We also refer to that path
name in ver_linux and various how-to files and Kconfig files.

The file got renamed away in commit 186128f753 ("docs-rst: add
documents to development-process"), and as Jaegeuk Kim points out, the
commit message for that change says "use symlinks instead of renames",
but then the commit itself actually does renames after all.

Maybe we should do the other files too, but for now this just adds the
minimal symlink back to the historical name, so that people looking for
Documentation/Changes will actually find what they are looking for, and
the debian scripts continue to work.

Jan Kara 82b0f8c39a mm: join struct fault_env and vm_fault
Currently we have two different structures for passing fault information
around - struct vm_fault and struct fault_env.  DAX will need more
information in struct vm_fault to handle its faults so the content of
that structure would become event closer to fault_env.  Furthermore it
would need to generate struct fault_env to be able to call some of the
generic functions.  So at this point I don't think there's much use in
keeping these two structures separate.  Just embed into struct vm_fault
all that is needed to use it for both purposes.

Linus Torvalds ce38207f16 sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
 
 Misc:
 - Replace all kthread usages with simple works

Linus Torvalds a829a8445f SCSI misc on 20161213
This update includes the usual round of major driver updates (ncr5380,
 lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).  There's also
 an assortment of minor fixes, mostly in error legs or other not very
 user visible stuff.  The major change is the pci_alloc_irq_vectors
 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the
 information.

  lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).

  There's also an assortment of minor fixes, mostly in error legs or
  other not very user visible stuff. The major change is the
  pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this
  effectively makes IRQ mapping generic for the drivers and allows
  blk_mq to use the information"

Linus Torvalds 5084fdf081 This merge request includes the dax-4.0-iomap-pmd branch which is
needed for both ext4 and xfs dax changes to use iomap for DAX.  It
 also includes the fscrypt branch which is needed for ubifs encryption
 work as well as ext4 encryption and fscrypt cleanups.
 
 Lots of cleanups and bug fixes, especially making sure ext4 is robust
 against maliciously corrupted file systems --- especially maliciously
 corrupted xattr blocks and a maliciously corrupted superblock.  Also
 fix ext4 support for 64k block sizes so it works well on ppcle.  Fixed
 mbcache so we don't miss some common xattr blocks that can be merged.

Linus Torvalds bb3dd056ed spi: Updates for v4.10
The nicest things about this release for me is seeing some older drivers
 getting some cleanups and modernization, it's really good to see things
 moving forwards even for older drivers.  In content terms it's a fairly
 humdrum release but where the work has been happening is great.
 
  - Support for simultaneous use of internal and GPIO chip selects for
    devices that require the use of the internal select even if it's not
    connected and a GPIO is actually routed to the slave device.
  - A major rework and cleanup of the fsl-espi driver from Heiner
    Kallweit which should make it work substantially better.
  - DMA support for Freescale DSPI IPs.
  - New drivers for Freescale LPSPI IPs and Marvell Armada 3700.
  - Support for Allwinner H3.

 "The nicest things about this release for me is seeing some older
  drivers getting some cleanups and modernization, it's really good to
  see things moving forwards even for older drivers.

  In content terms it's a fairly humdrum release but where the work has
  been happening is great.

   - Support for simultaneous use of internal and GPIO chip selects for
     devices that require the use of the internal select even if it's
     not connected and a GPIO is actually routed to the slave device.

   - A major rework and cleanup of the fsl-espi driver from Heiner
     Kallweit which should make it work substantially better.

   - DMA support for Freescale DSPI IPs.

   - New drivers for Freescale LPSPI IPs and Marvell Armada 3700.

   - Support for Allwinner H3"

Linus Torvalds 098c30557a Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1.
 
 Big thing here is the nice addition of "functional dependencies" to the
 driver core.  The idea has been talked about for a very long time, great
 job to Rafael for stepping up and implementing it. It's been tested for
 longer than the 4.9-rc1 date, we held off on merging it earlier in order
 to feel more comfortable about it.
 
 Other than that, it's just a handful of small other patches, some good
 cleanups to the mess that is the firmware class code, and we have a test
 driver for the deferred probe logic.

Linus Torvalds 72cca7baf4 Staging/IIO patches for 4.10-rc1
Here's the "big" staging/iio pull request for 4.10-rc1.
 
 Not as big as 4.9 was, but still just over a thousand changes.  We
 almost broke even of lines added vs. removed, as the slicoss driver was
 removed (got a "clean" driver for the same hardware through the netdev
 tree), and some iio drivers were also dropped, but I think we ended up
 adding a few thousand lines to the source tree in the end.  Other than
 that it's a lot of minor fixes all over the place, nothing major stands
 out at all.
 
 All of these have been in linux-next for a while.  There will be a merge
 conflict with Al's vfs tree in the lustre code, but the resolution for
 that should be pretty simple, that too has been in linux-next.

Linus Torvalds 36869cb93d Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe:
 "This is the main block pull request this series. Contrary to previous
  release, I've kept the core and driver changes in the same branch. We
  always ended up having dependencies between the two for obvious
  reasons, so makes more sense to keep them together. That said, I'll
  probably try and keep more topical branches going forward, especially
  for cycles that end up being as busy as this one.

  The major parts of this pull request is:

   - Improved support for O_DIRECT on block devices, with a small
     private implementation instead of using the pig that is
     fs/direct-io.c. From Christoph.

   - Request completion tracking in a scalable fashion. This is utilized
     by two components in this pull, the new hybrid polling and the
     writeback queue throttling code.

   - Improved support for polling with O_DIRECT, adding a hybrid mode
     that combines pure polling with an initial sleep. From me.

   - Support for automatic throttling of writeback queues on the block
     side. This uses feedback from the device completion latencies to
     scale the queue on the block side up or down. From me.

   - Support from SMR drives in the block layer and for SD. From Hannes
     and Shaun.

   - Multi-connection support for nbd. From Josef.

   - Cleanup of request and bio flags, so we have a clear split between
     which are bio (or rq) private, and which ones are shared. From
     Christoph.

   - A set of patches from Bart, that improve how we handle queue
     stopping and starting in blk-mq.

   - Support for WRITE_ZEROES from Chaitanya.

   - Lightnvm updates from Javier/Matias.

   - Supoort for FC for the nvme-over-fabrics code. From James Smart.

   - A bunch of fixes from a whole slew of people, too many to name
     here"

* 'for-4.10/block' of git://git.kernel.dk/linux-block: (182 commits)
  blk-stat: fix a few cases of missing batch flushing
  blk-flush: run the queue when inserting blk-mq flush

Linus Torvalds edc5f445a6 VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device
    interface, which essentially allows software defined devices to be
    exposed to users through VFIO.  The host vendor driver providing
    this virtual device polices, or mediates user access to the device.
    These devices often incorporate portions of real devices, for
    instance the primary initial users of this interface expose vGPUs
    which allow the user to map mediated devices, or mdevs, to a

Merge tag 'vfio-v4.10-rc1' of git://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:

 - VFIO updates for v4.10 primarily include a new Mediated Device
   interface, which essentially allows software defined devices to be
   exposed to users through VFIO. The host vendor driver providing this
   virtual device polices, or mediates user access to the device.

   These devices often incorporate portions of real devices, for
   instance the primary initial users of this interface expose vGPUs
   which allow the user to map mediated devices, or mdevs, to a portion
   of a physical GPU. QEMU composes these mdevs into PCI representations
   using the existing VFIO user API. This enables both Intel KVM-GT
   support, which is also expected to arrive into Linux mainline during
   the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
   devices (aka CCW devices) for s390 virtualization support. (Kirti

Linus Torvalds b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs

  - Oxford Semiconductor OX820 and OX810SE SoCs
  - Renesas RZ/G1M and RZ/GIE SoCs
  - Renesas R-Car RST driver for mode pin states
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver

Linus Torvalds edc57ea92c remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc
 driver to associate devices to the "running" state of the remoteproc,
 allowing devices to be probed and removed as the remote processor is
 booted, shut down or recovering from a crash.
 
 Handling of virtio device resources was improved, vring memory is now
 allocated as part of other memory allocation. This ensures that all
 vrings for all virtio devices are allocated before we boot the remote
 processor.
 
 The debugfs mechanism for starting and stopping remoteproc instances was
 replaced with a sysfs interface, also providing a mechanism for
 specifying firmware to use by the instance. This allows user space to
 load and boot use case specific firmware on remote processors.
 
 New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
 removal of the unused StE modem loader.
 
 Finally support for crash recovery in the Qualcomm Wirelss subsystem
 (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes
 and cleanups.

Linus Torvalds 5233c331cf It's been an busy period for mmc. Quite some changes in the mmc core, two new
mmc host drivers, some existing drivers being extended to support new IP
 versions and lots of other updates.
 
 MMC core:
  - Delete eMMC packed command support
  - Introduce mmc_abort_tuning() to enable eMMC tuning to fail gracefully
  - Introduce mmc_can_retune() to see if a host can be retuned
  - Re-work and improve the sequence when sending a CMD6 for mmc
  - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
  - Relax checking for CMD6 errors after switch to HS200
  - Re-factoring the code dealing with the mmc block queue
  - Recognize whether the eMMC card supports CMDQ
  - Fix 4K native sector check
  - Don't power off the card when starting the host
  - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
  - Improve error handling and drop meaningless BUG_ONs()
  - Lots of clean-ups and changes to improve the quality of the code
 
 MMC host:
  - sdhci: Fix tuning sequence and clean-up the related code
  - sdhci: Add support to via DT override broken SDHCI cap register bits
  - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant
  - sdhci-msm: Update clock management
  - sdhci-msm: Add support for eMMC HS400 mode
  - sdhci-msm: Deploy runtime/system PM support
  - sdhci-iproc: Extend driver support to newer IP versions
  - sdhci-pci: Add support for Intel GLK
  - sdhci-pci: Add support for Intel NI byt sdio
  - sdhci-acpi: Add support for 80860F14 UID 2 SDIO bus
  - sdhci: Lots of various small improvements and clean-ups
  - tmio: Add support for tuning
  - sh_mobile_sdhi: Add support for tuning
  - sh_mobile_sdhi: Extend driver to support SDHI IP on R7S72100 SoC
  - sh_mobile_sdhi: remove support for sh7372
  - davinci: Use mmc_of_parse() to enable generic mmc DT bindings
  - meson: Add new driver to support GX platforms
  - dw_mmc: Deploy generic runtime/system PM support
  - dw_mmc: Lots of various small improvements
 
 As a part of the mmc changes this time, I have also pulled in an immutable
 branch/tag (soc-device-match-tag1) hosted by Geert Uytterhoeven, to share the
 implementation of the new soc_device_match() interface. This is needed by the
 below mmc related changes:
  - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
  - soc: fsl: add GUTS driver for QorIQ platforms

Pull MMC updates from Ulf Hansson:
 "It's been an busy period for mmc. Quite some changes in the mmc core,
  two new mmc host drivers, some existing drivers being extended to
  support new IP versions and lots of other updates.

  MMC core:
   - Delete eMMC packed command support
   - Introduce mmc_abort_tuning() to enable eMMC tuning to fail
     gracefully
   - Introduce mmc_can_retune() to see if a host can be retuned
   - Re-work and improve the sequence when sending a CMD6 for mmc
   - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
   - Relax checking for CMD6 errors after switch to HS200
   - Re-factoring the code dealing with the mmc block queue
   - Recognize whether the eMMC card supports CMDQ
   - Fix 4K native sector check
   - Don't power off the card when starting the host
   - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
   - Improve error handling and drop meaningless BUG_ONs()
   - Lots of clean-ups and changes to improve the quality of the code

  MMC host:
   - sdhci: Fix tuning sequence and clean-up the related code
   - sdhci: Add support to via DT override broken SDHCI cap register
     bits

   - meson: Add new driver to support GX platforms
   - dw_mmc: Deploy generic runtime/system PM support
   - dw_mmc: Lots of various small improvements

  As a part of the mmc changes this time, I have also pulled in an
  immutable branch/tag (soc-device-match-tag1) hosted by Geert
  Uytterhoeven, to share the implementation of the new
  soc_device_match() interface. This is needed by these mmc related
  changes:

   - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
   - soc: fsl: add GUTS driver for QorIQ platforms"

Linus Torvalds 58f253d262 regulator: Updates for v4.10
A quiet release for the regulator API, conference season must've been
 slowing everyone down:
 
  - A new interface allowing drivers to provide an interface for reading
    a more detailed description of error conditions which allows devices
    using these regulators to build
  - ACPI support for the fixed voltage regulator.
  - Cleanups for the TI TWL drivers to reduce code duplication.

Linus Torvalds 20d5ba4928 Bulk pin control changes for the v4.10 kernel cycle:
No core changes this time. Mainly gradual improvement and
 feature growth in the drivers.
 
 New drivers:
 
 - New driver for TI DA850/OMAP-L138/AM18XX pinconf
 
 - The SX150x was moved over from the GPIO subsystem and
   reimagined as a pin control driver with GPIO support
   in a joint effort by three independent users of this
   hardware. The result was amazingly good!
 
 - New subdriver for the Oxnas OX820
 
 Improvements:
 
 - The sunxi driver now supports the generic pin control
   bindings rather than the sunxi-specific. Add debouncing
   support to the driver.
 
 - Simplifications in pinctrl-single adding a generic parser.
 
 - Two downstream fixes and move the Raspberry Pi BCM2835 over
   to use the generic GPIOLIB_IRQCHIP.

Linus Torvalds 061ad5038c Bulk GPIO changes for the v4.10 kernel cycle:
Core changes:
 
 - Simplify threaded interrupt handling: instead of passing
   numbed parameters to gpiochip_irqchip_add_chained() we
   create a new call: gpiochip_irqchip_add_nested() so the two
   types are clearly semantically different. Also make sure
   that all nested chips call gpiochip_set_nested_irqchip()
   which is necessary for IRQ resend to work properly if
   it happens.
 
 - Return error on seek operations for the chardev.
 
 - Clamp values set as part of gpio[d]_direction_output() so
   that anything != 0 will be send down to the driver as "1"
   not the value passed in.
 
 - ACPI can now support naming of GPIO lines, hogs and holes
   in the GPIO lists.
 
 New drivers:
 
 - The SX150x driver was deemed unfit for the GPIO subsystem
   and was moved over to a combined GPIO+pinctrl driver in the

Daniel Vetter c248891675 These are the documentation changes for 4.10.
It's another busy cycle for the docs tree, as the sphinx conversion
 continues.  Highlights include:
 
  - Further work on PDF output, which remains a bit of a pain but should be
    more solid now.
 
  - Five more DocBook template files converted to Sphinx.  Only 27 to go...
    Lots of plain-text files have also been converted and integrated.
 
  - Images in binary formats have been replaced with more source-friendly
    versions.
 
  - Various bits of organizational work, including the renaming of various
    files discussed at the kernel summit.
 
  - New documentation for the device_link mechanism.
 
 ...and, of course, lots of typo fixes and small updates.

Merge tag 'docs-4.10' of git://git.lwn.net/linux into drm-misc-next

Backmerge the docs-next branch from Jon into drm-misc so that we can
apply the dma-buf documentation cleanup patches. Git found a conflict
where there was none because both drm-misc and docs had identical
patches to clean up file rename issues in the rst include directives.

Kees Cook af884cd4a5 proc: report no_new_privs state
Similar to being able to examine if a process has been correctly
confined with seccomp, the state of no_new_privs is equally interesting,
so this adds it to /proc/$pid/status.

Hugh Dickins 49920d2878 mm: make transparent hugepage size public
Test programs want to know the size of a transparent hugepage.  While it
is commonly the same as the size of a hugetlbfs page (shown as
Hugepagesize in /proc/meminfo), that is not always so: powerpc
implements transparent hugepages in a different way from hugetlbfs
pages, so it's coincidence when their sizes are the same; and x86 and
others can support more than one hugetlbfs page size.

Add /sys/kernel/mm/transparent_hugepage/hpage_pmd_size to show the THP
size in bytes - it's the same for Anonymous and Shmem hugepages.  Call
it hpage_pmd_size (after HPAGE_PMD_SIZE) rather than hpage_size, in case
some transparent support for pud and pgd pages is added later.

Reza Arbab 39fa104d5b mm: remove x86-only restriction of movable_node
In commit c5320926e3 ("mem-hotplug: introduce movable_node boot
option"), the memblock allocation direction is changed to bottom-up and
then back to top-down like this:

1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node().
2. memblock_set_bottom_up(false), called by x86's numa_init().

Even though (1) occurs in generic mm code, it is wrapped by #ifdef
CONFIG_MOVABLE_NODE, which depends on X86_64.

This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches,
things will be unbalanced.  (1) will happen for them, but (2) will not.

This toggle was added in the first place because x86 has a delay between
adding memblocks and marking them as hotpluggable.  Since other arches
do this marking either immediately or not at all, they do not require
the bottom-up toggle.

So, resolve things by moving (1) from cmdline_parse_movable_node() to
x86's setup_arch(), immediately after the movable_node parameter has
been parsed.

Pull locking updates from Ingo Molnar:
 "The tree got pretty big in this development cycle, but the net effect
  is pretty good:

    115 files changed, 673 insertions(+), 1522 deletions(-)

  The main changes were:

   - Rework and generalize the mutex code to remove per arch mutex
     primitives. (Peter Zijlstra)

   - Add vCPU preemption support: add an interface to query the
     preemption status of vCPUs and use it in locking primitives - this
     optimizes paravirt performance. (Pan Xinhui, Juergen Gross,
     Christian Borntraeger)

   - Introduce cpu_relax_yield() and remov cpu_relax_lowlatency() to
     clean up and improve the s390 lock yielding machinery and its core
     kernel impact. (Christian Borntraeger)

   - Micro-optimize mutexes some more. (Waiman Long)

   - Reluctantly add the to-be-deprecated mutex_trylock_recursive()
     interface on a temporary basis, to give the DRM code more time to
     get rid of its locking hacks. Any other users will be NAK-ed on
     sight. (We turned off the deprecation warning for the time being to
     not pollute the build log.) (Peter Zijlstra)

   - Improve the rtmutex code a bit, in light of recent long lived
     bugs/races. (Thomas Gleixner)

Add per-Generation fallback bindings for R-Car SoCs.

This is in keeping with the compatibility string scheme is being adopted
for drivers for Renesas SoCs.

Also, improve readability by listing the rmobile fallback compatibility
string after the more-specific compatibility strings they provide a

Simon Horman ad4a8dc3fe i2c: rcar: Add per-Generation fallback bindings
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

Also:
* Deprecate renesas,i2c-rcar. It seems poorly named as it is only
  compatible with R-Car Gen 1. It also appears unused in mainline.
* Add some text to describe per-SoC bindings

Ondrej Kozina c538f6ec9f dm crypt: add ability to use keys from the kernel key retention service
The kernel key service is a generic way to store keys for the use of
other subsystems. Currently there is no way to use kernel keys in dm-crypt.
This patch aims to fix that. Instead of key userspace may pass a key
description with preceding ':'. So message that constructs encryption
mapping now looks like this:

  <cipher> [<key>|:<key_string>] <iv_offset> <dev_path> <start> [<#opt_params> <opt_params>]

where <key_string> is in format: <key_size>:<key_type>:<key_description>

Currently we only support two elementary key types: 'user' and 'logon'.
Keys may be loaded in dm-crypt either via <key_string> or using
classical method and pass the key in hex representation directly.

dm-crypt device initialised with a key passed in hex representation may be
replaced with key passed in key_string format and vice versa.

Niklas Cassel 4022d039a3 net: smmac: allow configuring lower pbl values
The driver currently always sets the PBLx8/PBLx4 bit, which means that
the pbl values configured via the pbl/txpbl/rxpbl DT properties are
always multiplied by 8/4 in the hardware.

In order to allow the DT to configure lower pbl values, while at the
same time not changing behavior of any existing device trees using the
pbl/txpbl/rxpbl settings, add a property to disable the multiplication
of the pbl by 8/4 in the hardware.

Niklas Cassel 89caaa2d80 net: stmmac: add support for independent DMA pbl for tx/rx
GMAC and newer supports independent programmable burst lengths for
DMA tx/rx. Add new optional devicetree properties representing this.

To be backwards compatible, snps,pbl will still be valid, but
snps,txpbl/snps,rxpbl will override the value in snps,pbl if set.

If the IP is synthesized to use the AXI interface, there is a register
and a matching DT property inside the optional stmmac-axi-config DT node
for controlling burst lengths, named snps,blen.
However, using this register, it is not possible to control tx and rx
independently. Also, this register is not available if the IP was
synthesized with, e.g., the AHB interface.

Netfilter/IPVS updates for net-next

The following patchset contains a large Netfilter update for net-next,
to summarise:

1) Add support for stateful objects. This series provides a nf_tables
   native alternative to the extended accounting infrastructure for
   nf_tables. Two initial stateful objects are supported: counters and
   quotas. Objects are identified by a user-defined name, you can fetch
   and reset them anytime. You can also use a maps to allow fast lookups
   using any arbitrary key combination. More info at:

   http://marc.info/?l=netfilter-devel&m=148029128323837&w=2

2) On-demand registration of nf_conntrack and defrag hooks per netns.
   Register nf_conntrack hooks if we have a stateful ruleset, ie.
   state-based filtering or NAT. The new nf_conntrack_default_on sysctl
   enables this from newly created netnamespaces. Default behaviour is not
   modified. Patches from Florian Westphal.

3) Allocate 4k chunks and then use these for x_tables counter allocation
   requests, this improves ruleset load time and also datapath ruleset
   evaluation, patches from Florian Westphal.

4) Add support for ebpf to the existing x_tables bpf extension.
   From Willem de Bruijn.

5) Update layer 4 checksum if any of the pseudoheader fields is updated.
   This provides a limited form of 1:1 stateless NAT that make sense in
   specific scenario, eg. load balancing.

6) Add support to flush sets in nf_tables. This series comes with a new
   set->ops->deactivate_one() indirection given that we have to walk
   over the list of set elements, then deactivate them one by one.
   The existing set->ops->deactivate() performs an element lookup that
   we don't need.

7) Two patches to avoid cloning packets, thus speed up packet forwarding
   via nft_fwd from ingress. From Florian Westphal.

8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
   prevent infinite loops, patch from Dwip Banerjee. And one minor
   refactoring from Gao feng.

9) Revisit recent log support for nf_tables netdev families: One patch
   to ensure that we correctly handle non-ethernet packets. Another
   patch to add missing logger definition for netdev. Patches from
   Liping Zhang.

10) Three patches for nft_fib, one to address insufficient register
    initialization and another to solve incorrect (although harmless)
    byteswap operation. Moreover update xt_rpfilter and nft_fib to match
    lbcast packets with zeronet as source, eg. DHCP Discover packets
    (0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.

11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
    Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
    been broken in many-cast mode for some little time, let's give them a
    chance by placing them at the same level as other existing protocols.
    Thus, users don't explicitly have to modprobe support for this and
    NAT rules work for them. Some people point to the lack of support in
    SOHO Linux-based routers that make deployment of new protocols harder.
    I guess other middleboxes outthere on the Internet are also to blame.
    Anyway, let's see if this has any impact in the midrun.

12) Skip software SCTP software checksum calculation if the NIC comes
    with SCTP checksum offload support. From Davide Caratti.

13) Initial core factoring to prepare conversion to hook array. Three
    patches from Aaron Conole.

14) Gao Feng made a wrong conversion to switch in the xt_multiport
    extension in a patch coming in the previous batch. Fix it in this
    batch.

15) Get vmalloc call in sync with kmalloc flags to avoid a warning
    and likely OOM killer intervention from x_tables. From Marcelo
    Ricardo Leitner.

16) Update Arturo Borrero's email address in all source code headers.

Grygorii Strashko 88f0f0b0be net: ethernet: ti: cpts: calc mult and shift from refclk freq
The cyclecounter mult and shift values can be calculated based on the
CPTS rfclk frequency and timekeepnig framework provides required algos
and API's.

Hence, calc mult and shift basing on CPTS rfclk frequency if both
cpts_clock_shift and cpts_clock_mult properties are not provided in DT (the
basis of calculation algorithm is borrowed from
__clocksource_update_freq_scale() commit 7d2f944a2b ("clocksource:
Provide a generic mult/shift factor calculation")). After this change
cpts_clock_shift and cpts_clock_mult DT properties will become optional.

           |--------------------- |PHY chip |
                                  ----------

The "mac_core_rst" represents "mac core reset signal", it resets
the mac core including packet processing unit, descriptor processing unit,
tx engine, rx engine, control unit.
The "mac_ifc_rst" represents "mac interface reset signal", it resets
the mac interface. The mac interface unit connects mac core and
data interface like MII/RMII/RGMII. After we set a new value of
interface mode, we must reset mac interface to reload the new mode value.
The "mac_core_rst" and "mac_ifc_rst" are both optional to be
backward compatible with the hix5hd2 SoC.
The "phy_rst" represents "phy reset signal", it does a hardware reset
on the PHY chip. This reset signal is optional if the PHY can work well
without the hardware reset.

Add one more clock signal, the existing is MAC core clock,
and the new one is MAC interface clock.
The MAC interface clock is optional to be backward compatible with
the hix5hd2 SoC.
