Florian Westphal 5c2a9644d0 bonding: update documentation section after dev->trans_start removal
Drivers that use LLTX need to update trans_start of the netdev_queue.
(Most drivers don't use LLTX; stack does this update if .ndo_start_xmit
 returned TX_OK).

Linus Torvalds 91ea692f87 Here are the latest bug fixes for ARM SoCs, mostly addressing
recent regressions. Changes are across several platforms, so
 I'm listing every change separately here.
 
 Regressions since 4.5:
 
  - A correction of the psci firmware DT binding, to prevent
    users from relying on unintended semantics
 
  - Actually getting the newly merged clock driver for some OMAP
    platforms to work
 
  - A revert of patches for the Qualcomm BAM, these need to be
    reworked for 4.7 to avoid breaking boards other than the one
    they were intended for
 
  - A correction for the I2C device nodes on the Socionext Uniphier
    platform
 
  - i.MX SDHCI was broken for non-DT platforms due to a change
    with the setting of the DMA mask
 
  - A revert of a patch that accidentally added a nonexisting
    clock on the Rensas "Porter" board
 
  - A couple of OMAP fixes that are all related to suspend after
    the power domain changes for dra7
 
  - On Mediatek, revert part of the power domain initialization
    changes that broke mt8173-evb
 
 Fixes for older bugs:
 
  - Workaround for an "external abort" in the omap34xx
    suspend/resume code.
 
  - The USB1/eSATA should not be listed as an excon device on
    am57xx-beagle-x15 (broken since v4.0)
 
  - A v4.5 regression in the TI AM33xx and AM43XX DT specifying
    incorrect DMA request lines for the GPMC
 
  - The jiffies calibration on Renesas platforms was incorrect
    for some modern CPU cores.
 
  - A hardware errata woraround for clockdomains on TI DRA7

Sudeep Holla 978fa43623 drivers: firmware: psci: unify enable-method binding on ARM {64,32}-bit systems
Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.

However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.

This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".

So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Kevin Hilman c0e309138b Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.
 
 It seems suspend worked earlier as things were only partially initialized,
 while now we initialize things properly for dra7.
 
 Note that the "ARM: OMAP: Catch callers of revision information prior
 to it being populated" had to be reverted as it caused bogus warnings
 for other SoCs because omap initcalls bail out based on revision being
 set to 0 for other SoCs. These initcalls will mostly just disappear
 when we drop support for omap3 legacy booting.
 
 Also included is a fix for dra7 sys_32k_ck clock source that is not
 enabled on boot making system fall back to using emulated clock.

Heiko Stuebner 5128de8512 phy: rockchip-emmc: adapt binding to specifiy register offset and length
The emmc-phy occupies a contiguous set of 8 registers inside the general
register files, so the reg property should specify this.

Heiko Stuebner 332184adff phy: rockchip-emmc: should be a child device of the GRF
The emmc-phy is fully enclosed in the general register files (GRF).
Therefore as seen from the device-tree it shouldn't be a separate platform-
device but instead a sub-device of the GRF - using the simply-mfd mechanism.

The driver entered the kernel in the current merge-window, so we can still
adapt the binding without needing a fallback, as the binding hasn't been
released with a full kernel yet.

The displayport-phy is fully enclosed in the general register files (GRF).

The driver entered the kernel in the current merge-window, so we can still
adapt the binding without needing a fallback, as the binding hasn't been

While the edp phy is fully part of the GRF, it doesn't have any separate
register set there, so doesn't get any register-area assigned.

Johannes Berg 57fbcce37b cfg80211: remove enum ieee80211_band
This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

David Ahern a6db4494d2 net: ipv4: Consider failed nexthops in multipath routes
Multipath route lookups should consider knowledge about next hops and not
select a hop that is known to be failed.

Example:

                     [h2]                   [h3]   15.0.0.5
                      |                      |
                     3|                     3|
                    [SP1]                  [SP2]--+
                     1  2                   1     2
                     |  |     /-------------+     |
                     |   \   /                    |
                     |     X                      |
                     |    / \                     |
                     |   /   \---------------\    |
                     1  2                     1   2
         12.0.0.2  [TOR1] 3-----------------3 [TOR2] 12.0.0.3
                     4                         4
                      \                       /
                        \                    /
                         \                  /
                          -------|   |-----/
                                 1   2
                                [TOR3]
                                  3|
                                   |
                                  [h1]  12.0.0.1

host h1 with IP 12.0.0.1 has 2 paths to host h3 at 15.0.0.5:

    root@h1:~# ip ro ls
    ...
    12.0.0.0/24 dev swp1  proto kernel  scope link  src 12.0.0.1
    15.0.0.0/16
            nexthop via 12.0.0.2  dev swp1 weight 1
            nexthop via 12.0.0.3  dev swp1 weight 1
    ...

If the link between tor3 and tor1 is down and the link between tor1
and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups
in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and
ssh 15.0.0.5 gets the other. Connections that attempt to use the
12.0.0.2 nexthop fail since that neighbor is not reachable:

    root@h1:~# ip neigh show
    ...
    12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE
    12.0.0.2 dev swp1  FAILED
    ...

The failed path can be avoided by considering known neighbor information
when selecting next hops. If the neighbor lookup fails we have no
knowledge about the nexthop, so give it a shot. If there is an entry
then only select the nexthop if the state is sane. This is similar to
what fib_detect_death does.

To maintain backward compatibility use of the neighbor information is
based on a new sysctl, fib_multipath_use_neigh.
