John Crispin 61976fff20 Documentation: devicetree: change the mediatek ethernet compatible string
When the binding was defined, I was not aware that mt2701 was an earlier
version of the SoC. For sake of consistency, the ethernet driver should
use mt2701 inside the compat string as this is the earliest SoC with the
ethernet core.

The ethernet driver is currently of no real use until we finish and
upstream the DSA driver. There are no users of this binding yet. It should
be safe to fix this now before it is too late and we need to provide
backward compatibility for the mt7623-eth compat string.

Martin Blumenstingl 7630ea4bda Documentation: net: phy: improve explanation when to specify the PHY ID
The old description basically read like "ethernet-phy-idAAAA.BBBB" can
be specified when you know the actual PHY ID. However, specifying this
has a side-effect: it forces Linux to bind to a certain PHY driver (the
one that matches the ID given in the compatible string), ignoring the ID
which is reported by the actual PHY.
Whenever a device is shipped with (multiple) different PHYs during it's
production lifetime then explicitly specifying
"ethernet-phy-idAAAA.BBBB" could break certain revisions of that device.

Yuriy Kolerov 92fdb527ee ARCv2: MCIP: Deprecate setting of affinity in Device Tree
Ignore value of interrupt distribution mode for common interrupts in
IDU since setting of affinity using value from Device Tree is deprecated
in ARC. Originally it is done in idu_irq_xlate() function and it is
semantically wrong and does not guaranty that an affinity value will be
set properly. idu_irq_enable() function is better place for
initialization of common interrupts.

By default send all common interrupts to all available online CPUs.
The affinity of common interrupts in IDU must be set manually since
in some cases the kernel will not call irq_set_affinity() by itself:

  1. When the kernel is not configured with support of SMP.
  2. When the kernel is configured with support of SMP but upper
     interrupt controllers does not support setting of the affinity
     and cannot propagate it to IDU.

Linus Torvalds cca112ecf2 spi: Fixes for v4.10
The usual small smattering of driver specific fixes.  A few bits that
 stand out here:
 
  - The R-Car patches adding fallbacks are just adding new compatible
    strings to the driver so that device trees are written in a more
    robustly future proof fashion, this isn't strictly a fix but it's
    just new IDs and it's better to get it into mainline sooner to
    improve the ABI.
  - The DesignWare "switch to new API part 2" patch is actually a
    misleadingly titled fix for a bit that got missed in the original
    conversion.

 2) Because of a logic bug, the user can't actually force SW

    checksumming bugs really annoying. Fix from Hayes Wang.

 3) VXLAN route lookup does not take the source and destination ports

 8) Openvswitch conntack actions need to maintain a correct checksum,

Greg Kroah-Hartman c7334ce814 Revert "driver core: Add deferred_probe attribute to devices in sysfs"
This reverts commit 6751667a29.

Rob Herring objected to it, and a replacement for it will be added using
debugfs in the future.

Dmitry Torokhov 331c342552 i2c: do not enable fall back to Host Notify by default
Falling back unconditionally to HostNotify as primary client's interrupt
breaks some drivers which alter their functionality depending on whether
interrupt is present or not, so let's introduce a board flag telling I2C
core explicitly if we want wired interrupt or HostNotify-based one:
I2C_CLIENT_HOST_NOTIFY.

For DT-based systems we introduce "host-notify" property that we convert
to I2C_CLIENT_HOST_NOTIFY board flag.

Alexander Duyck 4d09d0f45d mm: add documentation for page fragment APIs
This is a first pass at trying to add documentation for the page_frag
APIs.  They may still change over time but for now I thought I would try
to get these documented so that as more network drivers and stack calls
make use of them we have one central spot to document how they are meant
to be used.

 "This has one fix to make i915 work when using Xen SWIOTLB, and a
  feature from Geert to aid in debugging of devices that can't do DMA
  outside the 32-bit address space.

  The feature from Geert is on top of v4.10 merge window commit
  (specifically you pulling my previous branch), as his changes were
  dependent on the Documentation/ movement patches.

  I figured it would just easier than me trying than to cherry-pick the
  Documentation patches to satisfy git.

  The patches have been soaking since 12/20, albeit I updated the last
  patch due to linux-next catching an compiler error and adding an
  Tested-and-Reported-by tag"

Linus Torvalds b400792732 This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
 regressions introduced during the merge window, and about half of
 the changes are for mach-omap2.
 
 A couple of patches are just cleanups and dead code removal that I would
 not normally have considered for merging after -rc2, but I decided to
 take them along with the fixes this time.
 
 Notable fixes include:
 
 - removing the skeleton.dtsi include broke a number of machines, and we
   have to put empty /chosen nodes back to be able to pass kernel command
   lines as before
 
 - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200,
   as it had been for no good reason for a long time.

Lv Zheng 9c4aa1eecb ACPI / sysfs: Provide quirk mechanism to prevent GPE flooding
Sometimes, the users may require a quirk to be provided from ACPI subsystem
core to prevent a GPE from flooding.
Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents
the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx
provided via AML table, and OSPM is lacking of the knowledge to get
_Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may
still occur.

The existing quirk mechanism can be enabled/disabled using the following
commands to prevent such kind of GPE flooding during runtime:
 # echo mask > /sys/firmware/acpi/interrupts/gpe00
 # echo unmask > /sys/firmware/acpi/interrupts/gpe00
To avoid GPE flooding during boot, we need a boot stage mechanism.

This patch provides such a boot stage quirk mechanism to stop this kind of
GPE flooding. This patch doesn't fix any feature gap but since the new
feature gaps could be found in the future endlessly, and can disappear if
the feature gaps are filled, providing a boot parameter rather than a DMI
table should suffice.

Linus Torvalds eb254f323b Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner:
 "This provides support for Intel's Cache Allocation Technology, a cache
  partitioning mechanism.

  The interface is odd, but the hardware interface of that CAT stuff is
  odd as well.

  We tried hard to come up with an abstraction, but that only allows
  rather simple partitioning, but no way of sharing and dealing with the
  per package nature of this mechanism.

  In the end we decided to expose the allocation bitmaps directly so all
  combinations of the hardware can be utilized.

  There are two ways of associating a cache partition:

   - Task

     A task can be added to a resource group. It uses the cache
     partition associated to the group.

   - CPU

     All tasks which are not member of a resource group use the group to
     which the CPU they are running on is associated with.

     That allows for simple CPU based partitioning schemes.

  The main expected user sare:

   - Virtualization so a VM can only trash only the associated part of
     the cash w/o disturbing others

   - Real-Time systems to seperate RT and general workloads.

   - Latency sensitive enterprise workloads

   - In theory this also can be used to protect against cache side
     channel attacks"

[ Intel RDT is "Resource Director Technology". The interface really is
  rather odd and very specific, which delayed this pull request while I
  was thinking about it. The pull request itself came in early during
  the merge window, I just delayed it until things had calmed down and I
  had more time.

  But people tell me they'll use this, and the good news is that it is
  _so_ specific that it's rather independent of anything else, and no
  user is going to depend on the interface since it's pretty rare. So if
  push comes to shove, we can just remove the interface and nothing will
  break ]

Dongpo Li f7ca8e3b94 net: hix5hd2_gmac: fix compatible strings name
The SoC hix5hd2 compatible string has the suffix "-gmac" and
we should not change its compatible string.
So we should name all the compatible string with the suffix "-gmac".
Creating a new name suffix "-gemac" is unnecessary.

We also add another SoC compatible string in dt binding documentation
and describe which generic version the SoC belongs to.
