      Jani for co-maintainer!
      
      Jani has been a really active bug-scrubber in the past few months.
      I've asked him whether he wants to do this in a more official capacity
      and he agreed. I've already chatted with Dave and Jesse and they
      support this.
      
      Note that everyone can't now just relax because "Jani will do all the
      bug scrubbing" - au contraire expect more nagging and poking now that
      we have more bandwidth.
      
      Longer-term the plan is to share more of the maintainer duties, but we
      need to fix up the infrastructure a bit first (like moving the git
      repo to a common location).
      
      While at it also add the newly set-up patchwork instance.

      o Driver is using common tx_clean_lock for all Tx queues. This patch
        adds per queue tx_clean_lock.
      o Driver is not updating sw_consumer while processing Tx completion
        when interface is going down. Fixed in this patch.

      infiniband: make sure the src net is infiniband when create new link · 0d68fc4f
      Hangbin Liu authored
      When we create a new infiniband link with uninfiniband device, e.g. `ip link
      add link em1 type ipoib pkey 0x8001`. We will get a NULL pointer dereference
      cause other dev like Ethernet don't have struct ib_device.
      
      The code path is:
      rtnl_newlink
        |-- ipoib_new_child_link
              |-- __ipoib_vlan_add
                    |-- ipoib_set_dev_features
                          |-- ib_query_device
      
      Fix this bug by make sure the src net is infiniband when create new link.

      Even if user doesn't supply the physical netdev to attach vxlan dev
      to, and at the same time user want to vxlan sit top of IPv6, mark
      vxlan_dev flags with VXLAN_F_IPV6 to create IPv6 based socket.
      Otherwise kernel crashes safely every time spitting below messages,

      cxgb4: allow large buffer size to have page size · 940d9d34
      Thadeu Lima de Souza Cascardo authored
      Since commit 52367a76
      ("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"),
      we have failures like this during cxgb4 probe:
      
      cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536]
      cxgb4: probe of 0000:01:00.4 failed with error -22
      
      This happens whenever software parameters are used, without a
      configuration file. That happens when the hardware was already
      initialized (after kexec, or after csiostor is loaded).
      
      It happens that these values are acceptable, rendering fl_pg_order equal
      to 0, which is the case of a hard init when the page size is equal or
      larger than 65536.
      
      Accepting fl_large_pg equal to fl_small_pg solves the issue, and
      shouldn't cause any trouble besides a possible performance reduction
      when smaller pages are used. And that can be fixed by a configuration
      file.

      Linus Torvalds authored
      Pull ACPI and PM fixes and new device IDs from Rafael Wysocki:
       "These commits, except for one, are regression fixes and the remaining
        one fixes a divide error leading to a kernel panic.  The majority of
        the regressions fixed here were introduced during the 3.12 cycle, one
        of them is from this cycle and one is older.
      
        Specifics:
      
         - VGA switcheroo was broken for some users as a result of the
           ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some
           previously ignored hotplug events started to be handled.  The fix
           causes them to be ignored again.
      
         - There are two more issues related to cpufreq's suspend/resume
           handling changes from the 3.12 cycle addressed by Viresh Kumar's
           fixes.
      
         - intel_pstate triggers a divide error in a timer function if the
           P-state information it needs is missing during initialization.
           This leads to kernel panics on nested KVM clients and is fixed by
           failing the initialization cleanly in those cases.
      
         - PCI initalization code changes during the 3.9 cycle uncovered BIOS
           issues related to ACPI wakeup notifications (some BIOSes send them
           for devices that aren't supposed to support ACPI wakeup).  Work
           around them by installing an ACPI wakeup notify handler for all PCI
           devices with ACPI support.
      
         - The Calxeda cpuilde driver's probe function is tagged as __init,
           which is incorrect and causes a section mismatch to occur during
           build.  Fix from Andre Przywara removes the __init tag from there.
      
         - During the 3.12 cycle ACPIPHP started to print warnings about
           missing _ADR for devices that legitimately don't have it.  Fix from
           Toshi Kani makes it only print the warnings where they make sense"

      netpoll: Fix missing TXQ unlock and and OOPS. · aca5f58f
      David S. Miller authored
      The VLAN tag handling code in netpoll_send_skb_on_dev() has two problems.
      
      1) It exits without unlocking the TXQ.
      
      2) It then tries to queue a NULL skb to npinfo->txq.
