9099daed9c mm: kmemleak: avoid using __va() on addresses that don't have a lowmem mapping 
Some of the kmemleak_*() callbacks in memblock, bootmem, CMA convert a
physical address to a virtual one using __va().  However, such physical
addresses may sometimes be located in highmem and using __va() is
incorrect, leading to inconsistent object tracking in kmemleak.

The following functions have been added to the kmemleak API and they take
a physical address as the object pointer.  They only perform the
corresponding action if the address has a lowmem mapping:

kmemleak_alloc_phys
kmemleak_free_part_phys
kmemleak_not_leak_phys
kmemleak_ignore_phys

The affected calling places have been updated to use the new kmemleak
API.

bf72eda5f9 autofs: update struct autofs_dev_ioctl in Documentation 
Sync with changes made by commit 730c9eeca9 ("autofs4: improve
parameter usage") which introduced an union for various ioctl commands
instead of having statically named arg1,2.

This commit simply replaces arg1,2 with the corresponding fields without
changing semantics.

d873284103 autofs: fix Documentation regarding devid on ioctl

2d13e6ca42 lib/bitmap.c: enhance bitmap syntax 
Today there are platforms with many CPUs (up to 4K).  Trying to boot only
part of the CPUs may result in too long string.

For example lets take NPS platform that is part of arch/arc.  This
platform have SMP system with 256 cores each with 16 HW threads (SMT
machine) where HW thread appears as CPU to the kernel.  In this example
there is total of 4K CPUs.  When one tries to boot only part of the HW
threads from each core the string representing the map may be long...  For
example if for sake of performance we decided to boot only first half of
HW threads of each core the map will look like:
0-7,16-23,32-39,...,4080-4087

This patch introduce new syntax to accommodate with such use case.  I
added an optional postfix to a range of CPUs which will choose according
to given modulo the desired range of reminders i.e.:

    <cpus range>:sed_size/group_size

For example, above map can be described in new syntax like this:
0-4095:8/16

Note that this patch is backward compatible with current syntax.

Pull main rdma updates from Doug Ledford:
 "This is the main pull request for the rdma stack this release.  The
  code has been through 0day and I had it tagged for linux-next testing
  for a couple days.

  Summary:

   - updates to mlx5

   - updates to mlx4 (two conflicts, both minor and easily resolved)

   - updates to iw_cxgb4 (one conflict, not so obvious to resolve,
     proper resolution is to keep the code in cxgb4_main.c as it is in
     Linus' tree as attach_uld was refactored and moved into
     cxgb4_uld.c)

   - improvements to uAPI (moved vendor specific API elements to uAPI
     area)

   - add hns-roce driver and hns and hns-roce ACPI reset support

   - conversion of all rdma code away from deprecated
     create_singlethread_workqueue

   - security improvement: remove unsafe ib_get_dma_mr (breaks lustre in
     staging)"

c913fc4146 ARM: SoC: late DT updates for v4.9 
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

a439f8f287 ARM: 64-bit DT updates for v4.8 
The 64-bit DT changes are surprisingly small this time, we only add two
 SoC platforms: the ZTE ZX296718 Set-top-box SoC and the SocioNext
 UniPhier LD11 TV SoC, each with their reference boards.
 
 There are three new machines added for existing SoC platforms:
 
 - The Marvell Armada 8040 development board is an impressive quad-core
   Cortex-A72 machine with three 10gbit ethernet interfaces
 
 - Qualcomms DragonBoard 820c single-board computer is their current
   high-end phone platform in the 96boards form factor
 
 - Rockchip: Tronsmart Orion r86 set-top-box is a popular mid-range
   Android box based on the 8-core rk3368 SoC.

00e729c933 ARM: DT updates for v4.9 
These are as usual a very large number of mostly boring updates to
 enable devices in existing machines, or to fix minor bugs.  Notably,
 an ongoing treewide effort to fix warnings caused by an update to the
 device tree compiler. These are enabled with "make W=1" at the moment
 but can hopefully become the default once all issues have been addressed.
 
 No new SoC platform is added this time around (Armada 395 and Orion
 mv88f5181 are slight variations of existing ones), but a significant
 number of new dts files are added, which I list by platform:
 
 - Allwinner: Empire Electronix M712 and iNet d978 Rev2 tablets;
 	Orange Pi PC Plus, Orange Pi 2, Orange Pi Plus 2E,
 	Orange Pi Lite, Olimex A33-Olinuxino, and Nano Pi Neo
 	single-board computers
 
 - ARM Realview: all supported machines (ported from board files)
 
 - Broadcom: BCM958525er, BCM958522er, BCM988312hr, BCM958623hr and

6afd563d4b ARM: SoC driver updates for v4.9 
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - The Qualcomm external bus interface 2 (EBI2), used in some of their
   mobile phone chips for connecting flash memory, LCD displays or
   other peripherals
 
 - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the
   EFUSE based on that firmware interface.
 
 - Perf support for the AppliedMicro X-Gene performance monitor unit
 
 - Reset driver for STMicroelectronics STM32
 
 - Reset driver for SocioNext UniPhier SoCs
 
 Aside from these, there are minor updates to SoC-specific bus,
 clocksource, firmware, pinctrl, reset, rtc and pmic drivers.

66f2c6d952 ARM: SoC platform updates for v4.9 
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

6c6ef9f26e xattr: Stop calling {get,set,remove}xattr inode operations 
All filesystems that support xattrs by now do so via xattr handlers.
They all define sb->s_xattr, and their getxattr, setxattr, and
removexattr inode operations use the generic inode operations.  On
filesystems that don't support xattrs, the xattr inode operations are
all NULL, and sb->s_xattr is also NULL.

This means that we can remove the getxattr, setxattr, and removexattr
inode operations and directly call the generic handlers, or better,
inline expand those handlers into fs/xattr.c.

Filesystems that do not support xattrs on some inodes should clear the
IOP_XATTR i_opflags flag in those inodes.  (Right now, some filesystems
have checks to disable xattrs on some inodes in the ->list, ->get, and
->set xattr handler operations instead.)  The IOP_XATTR flag is
automatically cleared in inodes of filesystems that don't have xattr
support.

In orangefs, symlinks do have a setxattr iop but no getxattr iop.  Add a
check for symlinks to orangefs_inode_getxattr to preserve the current,
weird behavior; that check may not be necessary though.

 "This is the main pull request for block layer changes in 4.9.

  As mentioned at the last merge window, I've changed things up and now
  do just one branch for core block layer changes, and driver changes.
  This avoids dependencies between the two branches. Outside of this
  main pull request, there are two topical branches coming as well.

  This pull request contains:

   - A set of fixes, and a conversion to blk-mq, of nbd. From Josef.

   - Set of fixes and updates for lightnvm from Matias, Simon, and Arnd.
     Followup dependency fix from Geert.

   - General fixes from Bart, Baoyou, Guoqing, and Linus W.

   - CFQ async write starvation fix from Glauber.

   - Add supprot for delayed kick of the requeue list, from Mike.

   - Pull out the scalable bitmap code from blk-mq-tag.c and make it
     generally available under the name of sbitmap. Only blk-mq-tag uses
     it for now, but the blk-mq scheduling bits will use it as well.
     From Omar.

   - bdev thaw error progagation from Pierre.

   - Improve the blk polling statistics, and allow the user to clear
     them. From Stephen.

   - Set of minor cleanups from Christoph in block/blk-mq.

   - Set of cleanups and optimizations from me for block/blk-mq.

4dfddf5036 SCSI misc on 20161006 
This update includes the usual round of major driver updates (hpsa, be2iscsi,
 hisi_sas, zfcp, cxlflash).  There's a new incarnation of hpsa called smartpqi
 for which a driver is added, there's some cleanup work of the ibm vscsi target
 and updates to libfc, plus a whole host of minor fixes and updates and finally
 the removal of several ISA drivers which seem not to have been used for years.

3d9e133fe6 devicetree: net: micrel-ksz90x1.txt: Properly explain skew settings 
The KSZ9031 skew registers contain an offset, the chip's default value
is "neutral" which does not add any skew. Programming a 0 into a skew
property will actually set it the maximal negative adjustment and not
to a neutral position as one would expect.

Explain this situation in the devicetree binding documentation and list
the settings that the chip considers neutral.

Changing the implementation to accept negative values would have been
a better solution, but would break existing configurations.

553911c67e dmaengine updates for 4.8-rc1 
This is bit large pile of code which bring in some nice additions:
  - Error reporting: we have added a new mechanism for users of dmaenegine to
    register a callback_result which tells them the result of the dma
    transaction. Right now only one user ntb is using it.
  - As we discussed on KS mailing list and pointed out NO_IRQ has no place in
    kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and
    ppc users)
  - Support for IOMMU slave transfers and it implementation for arm.
  - To get better build coverage, enable COMPILE_TEST for bunch of driver,
    and fix the warning and sparse complaints on these.
  - Apart from above, usual updates spread across drivers.

d880e5ad0d remoteproc updates for v4.9 
In addition to a slew of minor fixes and cleanups these patches refactors how
 we deal with remoteprocs that will be auto-booting themselves, this in itself
 do clean up the remote resource handling but opens for additional work to
 clarify responsibilities and life cycles of resources. We also revise how
 module locking of remoteproc drivers work, so that they are locked as we hand
 out references to them to third parties, rather than only when booted by
 anyone.
 
 In addition to this we also introduce the Qualcomm Wireless Subsystem
 remoteproc driver.

4c1fad64ef In this round, we've investigated how f2fs deals with errors given by our fault 
injection facility. With this, we could fix several corner cases. And, in order
 to improve the performance, we set inline_dentry by default and enhance the
 exisiting discard issue flow. In addition, we added f2fs_migrate_page for better
 memory management.
 
 = Enhancement =
  - set inline_dentry by default
  - improve discard issue flow
  - add more fault injection cases in f2fs
  - allow block preallocation for encrypted files
  - introduce migrate_page callback function
  - avoid truncating the next direct node block at every checkpoint
 
 = Bug fixes =
  - set page flag correctly between write_begin and write_end
  - missing error handling cases detected by fault injection
  - preallocate blocks regarding to 4KB alignement correctly
  - dentry and filename handling of encryption
  - lost xattrs of directories

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've investigated how f2fs deals with errors given by
  our fault injection facility. With this, we could fix several corner
  cases. And, in order to improve the performance, we set inline_dentry
  by default and enhance the exisiting discard issue flow. In addition,
  we added f2fs_migrate_page for better memory management.

  Enhancements:
   - set inline_dentry by default
   - improve discard issue flow
   - add more fault injection cases in f2fs
   - allow block preallocation for encrypted files
   - introduce migrate_page callback function
   - avoid truncating the next direct node block at every checkpoint

  Bug fixes:
   - set page flag correctly between write_begin and write_end
   - missing error handling cases detected by fault injection
   - preallocate blocks regarding to 4KB alignement correctly
   - dentry and filename handling of encryption
   - lost xattrs of directories"

14986a34e1 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
Pull namespace updates from Eric Biederman:
 "This set of changes is a number of smaller things that have been
  overlooked in other development cycles focused on more fundamental
  change. The devpts changes are small things that were a distraction
  until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an
  trivial regression fix to autofs for the unprivileged mount changes
  that went in last cycle. A pair of ioctls has been added by Andrey
  Vagin making it is possible to discover the relationships between
  namespaces when referring to them through file descriptors.

  The big user visible change is starting to add simple resource limits
  to catch programs that misbehave. With namespaces in general and user
  namespaces in particular allowing users to use more kinds of
  resources, it has become important to have something to limit errant
  programs. Because the purpose of these limits is to catch errant
  programs the code needs to be inexpensive to use as it always on, and
  the default limits need to be high enough that well behaved programs
  on well behaved systems don't encounter them.

  To this end, after some review I have implemented per user per user
  namespace limits, and use them to limit the number of namespaces. The
  limits being per user mean that one user can not exhause the limits of
  another user. The limits being per user namespace allow contexts where
  the limit is 0 and security conscious folks can remove from their
  threat anlysis the code used to manage namespaces (as they have
  historically done as it root only). At the same time the limits being
  per user namespace allow other parts of the system to use namespaces.

  Namespaces are increasingly being used in application sand boxing
  scenarios so an all or nothing disable for the entire system for the
  security conscious folks makes increasing use of these sandboxes
  impossible.

  There is also added a limit on the maximum number of mounts present in
  a single mount namespace. It is nontrivial to guess what a reasonable
  system wide limit on the number of mount structure in the kernel would
  be, especially as it various based on how a system is using
  containers. A limit on the number of mounts in a mount namespace
  however is much easier to understand and set. In most cases in
  practice only about 1000 mounts are used. Given that some autofs
  scenarious have the potential to be 30,000 to 50,000 mounts I have set
  the default limit for the number of mounts at 100,000 which is well
  above every known set of users but low enough that the mount hash
  tables don't degrade unreaonsably.

  These limits are a start. I expect this estabilishes a pattern that
  other limits for resources that namespaces use will follow. There has
  been interest in making inotify event limits per user per user
  namespace as well as interest expressed in making details about what
  is going on in the kernel more visible"

Pull xfs and iomap updates from Dave Chinner:
 "The main things in this update are the iomap-based DAX infrastructure,
  an XFS delalloc rework, and a chunk of fixes to how log recovery
  schedules writeback to prevent spurious corruption detections when
  recovery of certain items was not required.

  The other main chunk of code is some preparation for the upcoming
  reflink functionality. Most of it is generic and cleanups that stand
  alone, but they were ready and reviewed so are in this pull request.

  Speaking of reflink, I'm currently planning to send you another pull
  request next week containing all the new reflink functionality. I'm
  working through a similar process to the last cycle, where I sent the
  reverse mapping code in a separate request because of how large it
  was. The reflink code merge is even bigger than reverse mapping, so
  I'll be doing the same thing again....

   - change of XFS mailing list to linux-xfs@vger.kernel.org

   - iomap-based DAX infrastructure w/ XFS and ext2 support

41844e3620 Staging/IIO patches for 4.9-rc1 
Here is the big staging and IIO driver pull request for 4.9-rc1.
 
 There are a lot of patches in here, the majority due to the
 drivers/staging/greybus/ subsystem being merged in with full development
 history that went back a few years, in order to preserve the work that
 those developers did over time.  This was done the same way that btrfs
 was merged into the tree, so all should be ok there.
 
 Lots and lots of tiny cleanups happened in the tree as well, due to the
 Outreachy application process and lots of other developers showing up
 for the first time to clean code up.  Along with those changes, we
 deleted a wireless driver, and added a raspberrypi driver (currently
 marked broken), and lots of new iio drivers.
 
 Overall the tree still shrunk with more lines removed than added, about
 10 thousand lines removed in total.  Full details are in the very long
 shortlog below.
 
 All of this has been in the linux-next tree with no issues.  There will
 be some merge problems with other subsystem trees, but those are all
 minor problems and shouldn't be hard to work out when they happen
 (MAINTAINERS and some lustre build problems with the IB tree.)

  about 10 thousand lines removed in total. Full details are in the very
  long shortlog below.

  All of this has been in the linux-next tree with no issues. There will
  be some merge problems with other subsystem trees, but those are all
  minor problems and shouldn't be hard to work out when they happen
  (MAINTAINERS and some lustre build problems with the IB tree)"

And furter from me asking for clarification about greybus:
 "Right now there is a phone from Motorola shipping with this code (a
  slightly older version, but the same tree), so even though Ara is not
  alive in the same form, the functionality is happening. We are working
  with the developers of that phone to merge the newer stuff in with
  their fork so they can use the upstream version in future versions of
  their phone product line.

  Toshiba has at least one chip shipping in their catalog that
  needs/uses this protocol over a Unipro link, and rumor has it that
  there might be more in the future.

  There are also other users of the greybus protocols, there is a talk
  next week at ELC that shows how it is being used across a network
  connection to control a device, and previous ELC talks have showed the
  protocol stack being used over USB to drive embedded Linux boards.
  I've also talked to some people who are starting to work to add a host
  controller driver to control arduinos as the greybus PHY protocols are
  very useful to control a serial/i2c/spio/whatever device across a
  random physical link, as it is a way to have a self-describing device
  be attached to a host without needing manual configuration.

  So yes, people are using it, and there is still the chance that it
  will show up in a phone/laptop/tablet/whatever from Google in the
  future as well, the tech isn't dead, even if the original large phone
  project happens to be"

5691f0e9a3 sound updates for 4.9-rc1 
Again the diffstat shows a widely distributed pattern at this cycle,
 as there've been many code cleanups and refactoring allover the places.
 Other than that, the development was relatively calm, and no big
 surprise shouldn't be expected.  Here are some highlights:
 
 Core:
 - Sequencer code refactoring / documentation updates
 - TLV code moved to uapi, following some relevant cleanups
 
 USB-Audio:
 - Lots of LINE6 driver fixes / updates
 - DragonFly and TEAC device quirk updates
 
 HD-audio:
 - Usual fixupes for Dell, Lenovo and HP machines
 - Link-audio time reporting capability
 
 ASoC:
 - Large refactoring of simple-card code to be shared with rcar
   driver
 - Removal of some duplicated ops over lots of CODEC drivers
 - Again quite a few Intel SKL driver updates
 - New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663
