 "The most important bit in here is the fix for input route caching from
  Eric Dumazet, it's a shame we couldn't fully analyze this in time for
  3.6 as it's a 3.6 regression introduced by the routing cache removal.

  Anyways, will send quickly to -stable after you pull this in.

  Other changes of note:

   1) Fix lockdep splats in team and bonding, from Eric Dumazet.

   2) IPV6 adds link local route even when there is no link local
      address, from Nicolas Dichtel.

   3) Fix ixgbe PTP implementation, from Jacob Keller.

   4) Fix excessive stack usage in cxgb4 driver, from Vipul Pandya.

   5) MAC length computed improperly in VLAN demux, from Antonio
      Quartulli."

can: mpc5xxx_can: fix section type conflict

2012-10-04T17:26:32+00:00

Since commit:
    6d99c4c can: mpc5xxx_can: make data used as *of_device_id.data const

both "struct mpc5xxx_can_data mpc5200_can_data" and "mpc5121_can_data" are
marked as "const" but also as "__devinitdata". This leads to the following
compile error:

drivers/net/can/mscan/mpc5xxx_can.c:383: error: mpc5200_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:383: error: mpc5200_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:388: error: mpc5121_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:388: error: mpc5121_can_data causes a section type conflict

This patch changes the "__devinitdata" to "__devinitconst" and marks the
"struct of_device_id mpc5xxx_can_table" as "const" and "__devinitconst", too.

Pull networking changes from David Miller:

 1) GRE now works over ipv6, from Dmitry Kozlov.

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 4) Make openvswitch network namespace aware, from Pravin B Shelar.

 5) IPV6 NAT implementation, from Patrick McHardy.

 6) Server side support for TCP Fast Open, from Jerry Chu and others.

 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

flexcan: disable bus error interrupts for the i.MX28

2012-10-01T21:18:21+00:00

Due to a bug in most Flexcan cores, the bus error interrupt needs
to be enabled. Otherwise we don't get any error warning or passive
interrupts. This is _not_ necessary for the i.MX28 and this patch
disables bus error interrupts if "berr-reporting" is not requested.
This avoids bus error flooding, which might harm, especially on
low-end systems.

To handle such quirks of the Flexcan cores, a hardware feature flag
has been introduced, also replacing the "hw_ver" variable. So far
nobody could tell what Flexcan core version is available on what
Freescale SOC, apart from the i.MX6Q and P1010, and which bugs or
features are present on the various "hw_rev".

this pull request is for net-next, for the v3.7 release cycle.
AnilKumar Ch contributed a fix for a segfault in the c_can driver,
which is triggered by an earlier commit [1] in net-next (so no backport
