a59b7e0246 mlxsw: spectrum_router: Correctly reallocate adjacency entries
mlxsw_sp_nexthop_group_mac_update() is called in one of two cases:

1) When the MAC of a nexthop needs to be updated
2) When the size of a nexthop group has changed

In the second case the adjacency entries for the nexthop group need to
be reallocated from the adjacency table. In this case we must write to
the entries the MAC addresses of all the nexthops that should be
offloaded and not only those whose MAC changed. Otherwise, these entries
would be filled with garbage data, resulting in packet loss.

Martin Blumenstingl says:

====================
stmmac: dwmac-meson8b: configurable RGMII TX delay

Currently the dwmac-meson8b stmmac glue driver uses a hardcoded 1/4
cycle (= 2ns) TX clock delay. This seems to work fine for many boards
(for example Odroid-C2 or Amlogic's reference boards) but there are
some others where TX traffic is simply broken.
There are probably multiple reasons why it's working on some boards
while it's broken on others:
- some of Amlogic's reference boards are using a Micrel PHY
- hardware circuit design
- maybe more...

iperf3 results on my Mecool BB2 board (Meson GXM, RTL8211F PHY) with
TX clock delay disabled on the MAC (as it's enabled in the PHY driver).
TX throughput was virtually zero before:

I get similar TX throughput on my Meson GXBB "MXQ Pro+" board when I
disable the PHY's TX-delay and configure a 4ms TX-delay on the MAC.
So changes to at least the RTL8211F PHY driver are needed to get it
working properly in all situations.

Changes since v4:
- add a fallback of 2ns (the value which was previously hardcoded) for
  the TX delay so we are backwards-compatible with older .dts'
- update the documentation with the new fallback value and add a small
  note that the "amlogic,tx-delay" property is ignored when the phy-mode
  is "rmii".

Changes since v3:
- rebased to apply against current net-next branch (fixes a conflict
  with d2ed0a7755 "net: ethernet: stmmac: fix of-node and
  fixed-link-phydev leaks")

Changes since v2:
- moved all .dts patches (3-7) to a separate series
- removed the default 2ns TX delay when phy-mode RGMII is specified
- (rebased against current net-next)

Changes since v1:
- renamed the devicetree property "amlogic,tx-delay" to
  "amlogic,tx-delay-ns", which makes the .dts easier to read as we can
  simply specify human-readable values instead of having "preprocessor
  defines and calculation in human brain". Thanks to Andrew Lunn for
  the suggestion!
- improved documentation to indicate when the MAC TX-delay should be
  configured and how to use the PHY's TX-delay
- changed the default TX-delay in the dwmac-meson8b driver from 2ns
  to 0ms when any of the rgmii-*id modes are used (the 2ns default
  value still applies for phy-mode "rgmii")
- added patches to properly reset the PHY on Meson GXBB devices and to
  use a similar configuration than the one we use on Meson GXL devices
  (by passing a phy-handle to stmmac and defining the PHY in the mdio0
  bus - patch 3-6)
- add the "amlogic,tx-delay-ns" property to all boards which are using
  the RGMII PHY (patch 7)

b765234e72 net: stmmac: dwmac-meson8b: make the RGMII TX delay configurable
Prior to this patch we were using a hardcoded RGMII TX clock delay of
2ns (= 1/4 cycle of the 125MHz RGMII TX clock). This value works for
many boards, but unfortunately not for all (due to the way the actual
circuit is designed, sometimes because the TX delay is enabled in the
PHY, etc.). Making the TX delay on the MAC side configurable allows us
to support all possible hardware combinations.

This allows fixing a compatibility issue on some boards, where the
RTL8211F PHY is configured to generate the TX delay. We can now turn
off the TX delay in the MAC, because otherwise we would be applying the
delay twice (which results in non-working TX traffic).

d5490f1f67 net: dt-bindings: add RGMII TX delay configuration to meson8b-dwmac
This allows configuring the RGMII TX clock delay. The RGMII clock is
generated by underlying hardware of the the Meson 8b / GXBB DWMAC glue.
The configuration depends on the actual hardware (no delay may be
needed due to the design of the actual circuit, the PHY might add this
delay, etc.).

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.

b976dc53ec drm/i915: Introduce IS_GEN9_BC for Skylake and Kabylake.
Along with GLK it was introduced the .is_lp and IS_GEN9_LP.
So, following the same simplification standard we can
put Skylake and Kabylake under the same bucket for most
of the things.

So let's add the IS_GEN9_BC for "Big Core" (non Atom based
platforms).

The i915_drv.c was let out of this patch on purpose
because that is really a decision per platform, just like
other cases where IS_KABYLAKE is different from IS_SKYLAKE.

v2: fix conflict with IS_LP and 3 new cases for this
    big core bucket:
    - intel_ddi.c: intel_ddi_get_link_dpll
    - intel_fbc.c: find_compression_threshold
    - i915_gem_gtt.c: gtt_write_workarounds

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.

059aa73482 nfs: Don't increment lock sequence ID after NFS4ERR_MOVED
Xuan Qi reports that the Linux NFSv4 client failed to lock a file
that was migrated. The steps he observed on the wire:

1. The client sent a LOCK request to the source server
2. The source server replied NFS4ERR_MOVED
3. The client switched to the destination server
4. The client sent the same LOCK request to the destination
   server with a bumped lock sequence ID
5. The destination server rejected the LOCK request with
   NFS4ERR_BAD_SEQID

RFC 3530 section 8.1.5 provides a list of NFS errors which do not
bump a lock sequence ID.

However, RFC 3530 is now obsoleted by RFC 7530. In RFC 7530 section
9.1.7, this list has been updated by the addition of NFS4ERR_MOVED.

These files were only including module.h for exception table
related functions.  We've now separated that content out into its
own file "extable.h" so now move over to that and avoid all the
extra header content in module.h that we don't really need to compile
these files.

e7088170e3 ia64: ensure exception table search users include extable.h
We start with a delete of a duplicate prototype in asm/exception.h
that no longer needs to exist, as it duplicates content in extable.h
and since that header is so small, there is no point trying to
avoid using it.

Then we make sure anyone using search_exception_tables directly or
via the ia64_done_with_exception macro has included extable.h

In the process, we remove an include of moduleloader.h that was
apparently not really required; it would have been fetching in
module.h and hence the previous location of the exception search
function prototypes, but we need not rely on that anymore.

82ed1ac9c2 ia64: move ia64_done_with_exception out of asm/uaccess.h
Move ia64_done_with_exception out of asm/uaccess.h (which is widely
used) and into asm/exception.h (like ARM has) and then ensure the
few callers of it include this new header.

Most of the other C content in asm files is implemented in macro form.
So we do that conversion at the same time as the move.

There are two C exception prototypes that move along with the macro.
One of them will become redundant when we switch over to using the
<linux/extable.h> instead of <linux/module.h> header in a subsequent
commit.

Also relocate a couple of the automated asm --> linux uaccess
conversions to preserve the linux and asm independent grouping, since
we are in the file at that location anyway.

6db6f0eae6 bridge: multicast to unicast
Implements an optional, per bridge port flag and feature to deliver
multicast packets to any host on the according port via unicast
individually. This is done by copying the packet per host and
changing the multicast destination MAC to a unicast one accordingly.

multicast-to-unicast works on top of the multicast snooping feature of
the bridge. Which means unicast copies are only delivered to hosts which
are interested in it and signalized this via IGMP/MLD reports
previously.

This feature is intended for interface types which have a more reliable
and/or efficient way to deliver unicast packets than broadcast ones
(e.g. wifi).

However, it should only be enabled on interfaces where no IGMPv2/MLDv1
report suppression takes place. This feature is disabled by default.

The initial patch and idea is from Felix Fietkau.

b668970e61 MIPS: Fix modversions
kernelci.org reports tons of build warnings for linux-next:

35	WARNING: "memcpy" [fs/fat/msdos.ko] has no CRC!
35	WARNING: "__copy_user" [fs/fat/fat.ko] has no CRC!
32	WARNING: EXPORT symbol "memset" [vmlinux] version generation failed, symbol will not be versioned.
32	WARNING: EXPORT symbol "copy_page" [vmlinux] version generation failed, symbol will not be versioned.
32	WARNING: EXPORT symbol "clear_page" [vmlinux] version generation failed, symbol will not be versioned.
32	WARNING: EXPORT symbol "__strncpy_from_user_nocheck_asm" [vmlinux] version generation failed, symbol will not be versioned.

The problem here is mainly the missing asm/asm-prototypes.h header file
that is supposed to include the prototypes for each symbol that is exported
from an assembler file.

A second problem is that the asm/uaccess.h header contains some but not
all the necessary declarations for the user access helpers.

Finally, the vdso build is broken once we add asm/asm-prototypes.h, so
we have to fix this at the same time by changing the vdso header. My
approach here is to just not look for exported symbols in the VDSO
assembler files, as the symbols cannot be exported anyway.

we cannot drop a reference to the drm_atomic_state from the fence release
