  with no known users remaining:

   - efm32 - added in 2011, first Cortex-M, no notable changes after 2013

   - picoxcell - added in 2011, abandoned after 2012 acquisition

   - prima2 - added in 20111, no notable changes since 2015

   - tango - added in 2015, sporadic changes until 2017, but abandoned

   - u300 - added in 2009, no notable changes since 2013

   - zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes

   - arch/c6x - added in 2011, but work stalled soon after that

  A number of other platforms on the original list turned out to still
  have users. In some cases there are out-of-tree patches and users that
  plan to contribute them in the future, in other cases the code is
  complete and works reliably"

====================
ptp: ptp_clockmatrix: Fix output 1 PPS alignment.

This series fixes a race condition that may result in the output clock
not aligned to internal 1 PPS clock.

Part of device initialization is to align the rising edge of output
clocks to the internal rising edge of the 1 PPS clock.  If the system
APLL and DPLL are not locked when this alignment occurs, the alignment
fails and a fixed offset between the internal 1 PPS clock and the
output clock occurs.

If a clock is dynamically enabled after power-up, the output clock
also needs to be aligned to the internal 1 PPS clock.

The Ethernet MAC and PHY are usually major consumers of power on boards
which may not be able to fully power off (those with no PMIC). Powering
down the MAC and internal PHY saves power while these boards are "off".

Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Add two helper functions to release one table and hooks from
   the netns and netlink event path.

2) Add table ownership infrastructure, this new infrastructure allows
   users to bind a table (and its content) to a process through the
   netlink socket.

Ocelot now uses include/linux/dsa/ocelot.h which makes use of
CONFIG_PACKING to pack/unpack bits into the Injection/Extraction Frame
Headers. So it needs to explicitly select it, otherwise there might be
build errors due to the missing dependency.

Support also transmitting frames using the custom "8899 A"
4 byte tag.

Qingfang came up with the solution: we need to pad the
ethernet frame to 60 bytes using eth_skb_pad(), then the
switch will happily accept frames with custom tags.

Broadcom PHY driver updates

Updates to the Broadcom PHY driver related to use with copper SFP modules.

Changed since v3:
-fixed kerneldoc error

Changed since v2:
-Create flag for PHY on SFP module and use that rather than accessing
 attached_dev directly in PHY driver

Changed since v1:
-Reversed conditional to reduce indentation
-Added missing setting of MII_BCM54XX_AUXCTL_MISC_WREN in
 MII_BCM54XX_AUXCTL_SHDWSEL_MISC register

bcm54xx_config_init was modifying the PHY LED configuration to enable link
and activity indications. However, some SFP modules (such as Bel-Fuse
SFP-1GBT-06) have no LEDs but use the LED outputs to control the SFP LOS
signal, and modifying the LED settings will cause the LOS output to
malfunction. Skip this configuration for PHYs which are bound to an SFP
bus.

The default configuration for the BCM54616S PHY may not match the desired

On cpu architectures w/o dma cache snooping, dma_unmap() is a
is a very expensive operation, because its resulting sync
needs to invalidate cpu caches.

Increase efficiency/performance by syncing only those sections
of the lan743x's rx ring buffers that are actually in use.

The buffers in the lan743x driver's receive ring are always 9K,
even when the largest packet that can be received (the mtu) is
much smaller. This performs particularly badly on cpu archs
without dma cache snooping (such as ARM): each received packet
results in a 9K dma_{map|unmap} operation, which is very expensive
because cpu caches need to be invalidated.

Careful measurement of the driver rx path on armv7 reveals that
the cpu spends the majority of its time waiting for cache
invalidation.

Optimize by keeping the rx ring buffer size as close as possible
to the mtu. This limits the amount of cache that requires
invalidation.

This optimization would normally force us to re-allocate all
ring buffers when the mtu is changed - a disruptive event,
because it can only happen when the network interface is down.

Remove the need to re-allocate all ring buffers by adding support
for multi-buffer frames. Now any combination of mtu and ring
buffer size will work. When the mtu changes from mtu1 to mtu2,
consumed buffers of size mtu1 are lazily replaced by newly
allocated buffers of size mtu2.

These optimizations double the rx performance on armv7.
Third parties report 3x rx speedup on armv8.

Tested with iperf3 on a freescale imx6qp + lan7430, both sides
set to mtu 1500 bytes, measure rx performance:

The following call path suggests that calling unregister_netdev on an
interface that is up will first bring it down.

enetc_pf_remove
-> unregister_netdev
   -> unregister_netdevice_queue
      -> unregister_netdevice_many
         -> dev_close_many
            -> __dev_close_many
               -> enetc_close
                  -> enetc_stop
                     -> phylink_stop

However, enetc first destroys the phylink instance, then calls
unregister_netdev. This is already dissimilar to the setup (and error
path teardown path) from enetc_pf_probe, but more than that, it is buggy
because it is invalid to call phylink_stop after phylink_destroy.

So let's first unregister the netdev (and let the .ndo_stop events
consume themselves), then destroy the phylink instance, then free the
netdev.

net: mvneta: implement basic MQPrio support

This is V2 for the MQPrio support in mvneta.

This small series adds basic support for mqprio offloading, by having
the rx queueing mirroring the TCs based on VLAN prio fields.

This was tested on Armada 3700, and proves useful to make sure
high-priority traffic has a better chance not getting dropped when
there's lots of packets incoming.

The first patch of the series deals with the per-cpu interrupts on the
armada 3700. Since they don't work, there were already some patches
applied to keep all queue mappings to CPU0, but there still were some
remaining mappings left to be dealt with.

The second patch implements the MQPrio offloading for the receive path.

Changes in V2 :
 - Add a Fixes tag for the first patch
 - Fix some warnings and the xmas tree in the second patch
