0a55c12f97 net: phy: Add Wake-on-LAN driver for Microsemi PHYs.
Wake-on-LAN (WoL) is an Ethernet networking standard that allows
a computer/device to be turned on or awakened by a network message.

VSC8531 PHY can support this feature configure by driver set function.
WoL status get by driver get function.

Tested on Beaglebone Black with VSC 8531 PHY.

Paul Durrant says:

====================
xen-netback: guest rx side refactor

This series refactors the guest rx side of xen-netback:

- The code is moved into its own source module.

- The prefix variant of GSO handling is retired (since it is no longer
  in common use, and alternatives exist).

- The code is then simplified and modifications made to improve
  performance.

v2:
- Rebased onto refreshed net-next

a37f12298c xen-netback: batch copies for multiple to-guest rx packets
Instead of flushing the copy ops when an packet is complete, complete
packets when their copy ops are done.  This improves performance by
reducing the number of grant copy hypercalls.

Latency is still limited by the relatively small size of the copy
batch.

eb1723a29b xen-netback: refactor guest rx
Refactor the to-guest (rx) path to:

1. Push responses for completed skbs earlier, reducing latency.

2. Reduce the per-queue memory overhead by greatly reducing the
   maximum number of grant copy ops in each hypercall (from 4352 to
   64).  Each struct xenvif_queue is now only 44 kB instead of 220 kB.

3. Make the code more maintainable.

fedbc8c132 xen-netback: retire guest rx side prefix GSO feature
As far as I am aware only very old Windows network frontends make use of
this style of passing GSO packets from backend to frontend. These
frontends can easily be replaced by the freely available Xen Project
Windows PV network frontend, which uses the 'default' mechanism for
passing GSO packets, which is also used by all Linux frontends.

NOTE: Removal of this feature will not cause breakage in old Windows
      frontends. They simply will no longer receive GSO packets - the
      packets instead being fragmented in the backend.

3254f83694 xen-netback: separate guest side rx code into separate module
The netback source module has become very large and somewhat confusing.
This patch simply moves all code related to the backend to frontend (i.e
guest side rx) data-path into a separate rx source module.

This patch contains no functional change, it is code movement and
minimal changes to avoid patch style-check issues.

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 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....

a6a198bc60 xen/x86: Update topology map for PV VCPUs
Early during boot topology_update_package_map() computes
logical_pkg_ids for all present processors.

Later, when processors are brought up, identify_cpu() updates
these values based on phys_pkg_id which is a function of
initial_apicid. On PV guests the latter may point to a
non-existing node, causing logical_pkg_ids to be set to -1.

Intel's RAPL uses logical_pkg_id (as topology_logical_package_id())
to index its arrays and therefore in this case will point to index
65535 (since logical_pkg_id is a u16). This could lead to either a
crash or may actually access random memory location.

As a workaround, we recompute topology during CPU bringup to reset
logical_pkg_id to a valid value.

(The reason for initial_apicid being bogus is because it is
initial_apicid of the processor from which the guest is launched.
This value is CPUID(1).EBX[31:24])

fb833b1fbb ARM: fix delays
Commit 215e362daf ("ARM: 8306/1: loop_udelay: remove bogomips value
limitation") tried to increase the bogomips limitation, but in doing
so messed up udelay such that it always gives about a 5% error in the
delay, even if we use a timer.

The calculation is:

	loops = UDELAY_MULT * us_delay * ticks_per_jiffy >> UDELAY_SHIFT

Originally, UDELAY_MULT was ((UL(2199023) * HZ) >> 11) and UDELAY_SHIFT
30.  Assuming HZ=100, us_delay of 1000 and ticks_per_jiffy of 1660000
(eg, 166MHz timer, 1ms delay) this would calculate:

	((UL(2199023) * HZ) >> 11) * 1000 * 1660000 >> 30
		=> 165999

With the new values of 2047 * HZ + 483648 * HZ / 1000000 and 31, we get:

	(2047 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
		=> 158269

which is incorrect.  This is due to a typo - correcting it gives:

	(2147 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
		=> 165999

i.o.w, the original value.

sparc64: PCIe performance enhancements

Ver 2 is redone for 4.8 where commit 00085f1efa
changed DMA attributes from struct pointer to unsigned long.

This set of patches initiates a series of PCIe performance enhancement patch
submittals.

Patch 1/2 enables version 2 of the SPARC sun4v IOMMU I/O address translation
services need for subsequent enhancements.

Patch 2/2 allows drivers to specify DMA_ATTR_WEAK_ORDERING via DMA attributes
to the SPARC DMA mapping routines enabling "relaxed ordering" for the buffer
being mapped.

aa7bde1a8b sparc64: Enable setting "relaxed ordering" in IOMMU mappings
Enable relaxed ordering for memory writes in IOMMU TSB entry from
dma_4v_alloc_coherent(), dma_4v_map_page() and dma_4v_map_sg() when
dma_attrs DMA_ATTR_WEAK_ORDERING is set. This requires PCI IOMMU I/O
Translation Services version 2.0 API.

Many PCIe devices allow enabling relaxed-ordering (memory writes bypassing
other memory writes) for various DMA buffers. A notable exception is the
Mellanox mlx4 IB adapter. Due to the nature of x86 HW this appears to have
little performance impact there. On SPARC HW however, this results in major
performance degradation getting only about 3Gbps. Enabling RO in the IOMMU
entries corresponding to mlx4 data buffers increases the throughput to
about 13 Gbps.

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"

Linus Torvalds
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.

     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"
