21d9629a7a Fixing a bug in team driver due to incorrect 'unsigned int' to 'int' conversion 
Roundrobin runner of team driver uses 'unsigned int' variable to count
the number of sent_packets. Later it is passed to a subroutine
team_num_to_port_index(struct team *team, int num) as 'num' and when
we reach MAXINT (2**31-1), 'num' becomes negative.

This leads to using incorrect hash-bucket for port lookup
and as a result, packets are dropped. The fix consists of changing
'int num' to 'unsigned int num'. Testing of a fixed kernel shows that
there is no packet drop anymore.

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

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....

  Summary for this update:

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

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

   - small iomap fixes and additions

   - more efficient XFS delayed allocation infrastructure based on iomap

Pull ARM updates from Russell King:

 - Correct ARMs dma-mapping to use the correct printk format strings.

 - Avoid defining OBJCOPYFLAGS globally which upsets lkdtm rodata
   testing.

 - Cleanups to ARMs asm/memory.h include.

 - L2 cache cleanups.

 - Allow flat nommu binaries to be executed on ARM MMU systems.

 - Kernel hardening - add more read-only after init annotations,
   including making some kernel vdso variables const.

 - Ensure AMBA primecell clocks are appropriately defaulted.

 - ARM breakpoint cleanup.

 - Various StrongARM 11x0 and companion chip (SA1111) updates to bring
   this legacy platform to use more modern APIs for (eg) GPIOs and
   interrupts, which will allow us in the future to reduce some of the
   board-level driver clutter and elimate function callbacks into board
   code via platform data. There still appears to be interest in these
   platforms!

 - Remove the now redundant secure_flush_area() API.

 - Module PLT relocation optimisations. Ard says: This series of 4
   patches optimizes the ARM PLT generation code that is invoked at
   module load time, to get rid of the O(n^2) algorithm that results in
   pathological load times of 10 seconds or more for large modules on
   certain STB platforms.

 - ARMv7M cache maintanence support.

 - L2 cache PMU 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.)

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"

6a497e9d58 This is the bulk of GPIO changes for the v4.9 series: 
Subsystem improvements:
 
 - Do away with the last users of the obsolete Kconfig options
   ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
   always sounded like an item on a wishlist to Santa Claus to
   me). We can now select GPIOLIB and be done with it, for all
   archs. After some struggle it even work on UM. Not that it has
   GPIO, but if it wants to, it can select the library.
 
 - Continued efforts to make drivers properly either tristate or
   bool.
 
 - Introduce a warning for drivers assigning default triggers to
   their irqchip lines when probed from device tree, so we find and
   fix these ambigous drivers. It is agreed that in the OF config
   path, the device tree defines trigger characteristics.
 
 - The same warning, mutatis mutandis, for ACPI-probed GPIO
   irqchips.
 
 - We introduce the ability to mark certain IRQ lines as "unusable"
   as they can be taken by BIOS/firmware, unrouted in silicon and
   generally nasty if you use them, and such things. This is
   put to good use in the STMPE driver and also in the Cherryview
   pin control driver.
 
 - A new "mockup" virtual GPIO device that can be used for testing.
   The plan is to add unit tests under tools/* for exercising this
   device and verify that the kernel code paths are working as they
   should.
 
 - Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
   implicit all the time, but when people started building UM
   with allyesconfig or allmodconfig it exploded in their face.
 
 - Move some stray bits of device tree and ACPI HW description
   callbacks down into their respective implementation silo. These
   were causing issues when compiling on !HAS_IOMEM as well, so
   now eventually UM compiles the GPIOLIB library if it wants to.
 
 New drivers:
 
 - New driver for the Aspeed GPIO front-end companion to the
   pin controller merged through the pin control tree.
 
 - New driver for the LP873x PMIC GPIO portions.
 
 - New driver for Technologic Systems' I2C FPGA GPIO such as
   TS4900, TS-7970, TS-7990 and TS-4100.
 
 - New driver for the Broadcom BCM63xx series including BCM6338
   and BCM6345.
 
 - New driver for the Intel WhiskeyCove PMIC GPIO.
 
 - New driver for the Allwinner AXP209 PMIC GPIO portions.
 
 - New driver for Diamond Systems 48 line GPIO-MM, another of
   these port-mapped I/O expansion cards.
 
 - Support the STMicroelectronics STMPE1600 variant in the STMPE
   driver.
 
 Driver improvements:
 
 - The STMPE driver now supports rising/falling edge detection
   properly for IRQs.
 
 - The PCA954x will now fetch and enable its VCC regulator properly.
 
 - Major rework of the PCA953x driver with the goal of eventually
   switching it over to use regmap and thus modernize it even more.
 
 - Switch the IOP driver to use the generic MMIO GPIO library.
 
 - Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
   over to this subsystem from MFD, achieveing some separation of
   concerns.

   - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
     implicit all the time, but when people started building UM with
     allyesconfig or allmodconfig it exploded in their face.

   - move some stray bits of device tree and ACPI HW description
     callbacks down into their respective implementation silo. These
     were causing issues when compiling on !HAS_IOMEM as well, so now
     eventually UM compiles the GPIOLIB library if it wants to.

  New drivers:

   - new driver for the Aspeed GPIO front-end companion to the pin
     controller merged through the pin control tree.

   - new driver for the LP873x PMIC GPIO portions.

   - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
     TS-7970, TS-7990 and TS-4100.

   - new driver for the Broadcom BCM63xx series including BCM6338 and
     BCM6345.

   - new driver for the Intel WhiskeyCove PMIC GPIO.

   - new driver for the Allwinner AXP209 PMIC GPIO portions.

   - new driver for Diamond Systems 48 line GPIO-MM, another of these
     port-mapped I/O expansion cards.

   - support the STMicroelectronics STMPE1600 variant in the STMPE
     driver.

  Driver improvements:

   - the STMPE driver now supports rising/falling edge detection
     properly for IRQs.

   - the PCA954x will now fetch and enable its VCC regulator properly.

   - major rework of the PCA953x driver with the goal of eventually
     switching it over to use regmap and thus modernize it even more.

   - switch the IOP driver to use the generic MMIO GPIO library.

   - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
     over to this subsystem from MFD, achieveing some separation of
     concerns"

  RIP  page_cache_tree_insert+0xf1/0x100

This is a long-standing bug in the way shadow entries are accounted in
the radix tree nodes. The shrinker needs to know when radix tree nodes
contain only shadow entries, no pages, so node->count is split in half
to count shadows in the upper bits and pages in the lower bits.

Unfortunately, the radix tree implementation doesn't know of this and
assumes all entries are in node->count. When there is a shadow entry
directly in root->rnode and the tree is later extended, the radix tree
implementation will copy that entry into the new node and and bump its
node->count, i.e. increases the page count bits. Once the shadow gets
removed and we subtract from the upper counter, node->count underflows
and triggers the warning. Afterwards, without node->count reaching 0
again, the radix tree node is leaked.

Limit shadow entries to when we have actual radix tree nodes and can
count them properly. That means we lose the ability to detect refaults
from files that had only the first page faulted in at eviction time.

Fixes: 449dd6984d ("mm: keep page cache radix tree nodes in check")

  The patch from Richard updates the list of features we support and
  report back to userspace; this should have been sent earlier with the

  The second patch fixes a problem reported by our Android friends where

5617c122e6 The core clk framework changes are small again. They're mostly minor fixes 
that weren't causing enough problems (or any problems when we're just
 clarifying things) to warrant sending outside the merge window. The
 majority of changes are in drivers for various SoCs. Full details
 are in the logs, but here's the summary.
 
 Core:
 
  - Better support for DeviceTree overlays with the addition of the
    CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver
    for a device node that matched during of_clk_init(), unless
    the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE.
    This allows overlays to work cleanly for drivers that must probe
    before the device model is ready, and also after it's ready
    when an overlay is loaded.
 
  - Clarification in the code around how clk_hw pointers are returned
    from of clk providers
 
  - Proper migration of prepare/enable counts to parents when the
    clk tree is constructed
 
 New Drivers:
 
  - Socionext's UniPhier SoCs
  - Loongson1C
  - ZTE ZX296718
  - Qualcomm MDM9615
  - Amlogic GXBB AO clocks and resets
  - Broadcom BCM53573 ILP
  - Maxim MAX77620
 
 Updates:
 
  - Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s,
    A23 and A33)
  - Exynos 5xxx audio and DRAM clks
  - Loongson1B AC97, DMA and NAND clks
  - Rockchip DDR clks and rk3399 driver tweaks
  - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks
  - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
  - Amlogic GXBB MMC gate clks
  - at91 sama5d4 sckc
  - Removal of STiH415 and STiH416 clk support as the SoC is being removed
  - Rework of STiH4xx clk support for new style bindings
  - Continuation of driver migration to clk_hw based registration APIs
  - xgene PMD support

  - ARM versatile ICST

1e1430d528 Merge remote-tracking branch 'net-next/master' into mac80211-next 
Resolve the merge conflict between Felix's/my and Toke's patches
coming into the tree through net and mac80211-next respectively.
Most of Felix's changes go away due to Toke's new infrastructure
work, my patch changes to "goto begin" (the label wasn't there
before) instead of returning NULL so flow control towards drivers
is preserved better.

c0cd1ba4f8 net/ncsi: Introduce ncsi_stop_dev() 
This introduces ncsi_stop_dev(), as counterpart to ncsi_start_dev(),
to stop the NCSI device so that it can be reenabled in future. This
API should be called when the network device driver is going to
shutdown the device. There are 3 things done in the function: Stop
the channel monitoring; Reset channels to inactive state; Report
NCSI link down.

a4cc96d1f0 net: phy: Add Edge-rate driver for Microsemi PHYs. 
Edge-rate:
As system and networking speeds increase, a signal's output transition,
also know as the edge rate or slew rate (V/ns), takes on greater importance
because high-speed signals come with a price. That price is an assortment of
interference problems like ringing on the line, signal overshoot and
undershoot, extended signal settling times, crosstalk noise, transmission
line reflections, false signal detection by the receiving device and
electromagnetic interference (EMI) -- all of which can negate the potential
gains designers are seeking when they try to increase system speeds through
the use of higher performance logic devices. The fact is, faster signaling
edge rates can cause a higher level of electrical noise or other type of
interference that can actually lead to slower line speeds and lower maximum
system frequencies. This parameter allow the board designers to change the
driving strange, and thereby change the EMI behavioral.

Edge-rate parameters (vddmac, edge-slowdown) get from Device Tree.

Tested on Beaglebone Black with VSC 8531 PHY.

21f54ddae4 Using BUG_ON() as an assert() is _never_ acceptable 
That just generally kills the machine, and makes debugging only much
harder, since the traces may long be gone.

Debugging by assert() is a disease.  Don't do it.  If you can continue,
you're much better off doing so with a live machine where you have a
much higher chance that the report actually makes it to the system logs,
rather than result in a machine that is just completely dead.

The only valid situation for BUG_ON() is when continuing is not an
option, because there is massive corruption.  But if you are just
verifying that something is true, you warn about your broken assumptions
(preferably just once), and limp on.
