      alpha: select CONFIG_ARCH_USE_CMPXCHG_LOCKREF. · 8f8dcb3f
      Matt Turner authored
      On Alpha we have spinlocks that are 32b in size and an efficient
      cmpxchg64 implementation, so we qualify to make use of cmpxchg backed
      lockrefs. Select the ARCH_USE_CMPXCHG_LOCKREF Kconfig symbol and provide
      a trivial implementation of arch_spin_value_unlocked to satisfy the
      lockref code.

         1) Netlink_sendmsg() doesn't check iterator type properly in mmap

         2) Don't sleep in atomic context in bcmgenet driver, from Florian

         3) The pfkey_broadcast() code patch can't actually ever use anything
            other than GFP_ATOMIC.  And the cases that right now pass
            GFP_KERNEL or similar will currently trigger an RCU splat.  Just
            use GFP_ATOMIC unconditionally.  From David Ahern.
      
         4) Fix FD bit timings handling in pcan_usb driver, from Marc
            Kleine-Budde.
      
         5) Cache dst leaked in ip6_gre tunnel removal, fix from Huaibin Wang.
      
         6) Traversal into drivers/net/ethernet/renesas should be triggered by
            CONFIG_NET_VENDOR_RENESAS, not a particular driver's config
            option.  From Kazuya Mizuguchi.
      
         7) Fix regression in handling of igmp_join errors in vxlan, from
            Marcelo Ricardo Leitner.
      
         8) Make phy_{read,write}_mmd_indirect() properly take the mdio_lock
            mutex when programming the registers.  From Russell King.
      
         9) Fix non-forced handling in u32_destroy(), from WANG Cong.
      
        10) Test the EVENT_NO_RUNTIME_PM flag before it is cleared in
            usbnet_stop(), from Eugene Shatokhin.
      
        11) In sfc driver, don't fetch statistics firmware isn't capable of,

      Pull nvdimm fixlet from Dan Williams:
       "This is a libnvdimm ABI fixup.
      
        I pushed back on this change quite hard given the late date, that it
        appears to be purely cosmetic, sysfs is not necessarily meant to be a
        user friendly UI, and the kernel interprets the reversed polarity of
        the ACPI_NFIT_MEM_ARMED flag correctly.  When this flag is set, the
        energy source of an NVDIMM is not armed and any new writes to the DIMM
        may not be preserved.
      
        However, Bob Moore warned me that it is important to get these things
        named correctly wherever they appear otherwise we run the risk of a
        less than cautious firmware engineer implementing the polarity the
        wrong way.  Once a mistake like that escapes into production platforms
        the flag becomes useless and we need to move to a new bit position.
      
        Bob has agreed to take a change through ACPICA to rename
        ACPI_NFIT_MEM_ARMED to ACPI_NFIT_MEM_NOT_ARMED, and the patch below
        from Toshi brings the sysfs representation of these flags in line with
        their respective polarities.
      
        Please pull for 4.2 as this is the first kernel to expose the ACPI
        NFIT sysfs representation, and this is likely a kernel that firmware
        developers will be using for checking out their NVDIMM enabling"

      sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE state · f648f807
      lucien authored
      Commit f8d96052 ("sctp: Enforce retransmission limit during shutdown")
      fixed a problem with excessive retransmissions in the SHUTDOWN_PENDING by not
      resetting the association overall_error_count.  This allowed the association
      to better enforce assoc.max_retrans limit.
      
      However, the same issue still exists when the association is in SHUTDOWN_RECEIVED
      state.  In this state, HB-ACKs will continue to reset the overall_error_count
      for the association would extend the lifetime of association unnecessarily.
      
      This patch solves this by resetting the overall_error_count whenever the current
      state is small then SCTP_STATE_SHUTDOWN_PENDING.  As a small side-effect, we
      end up also handling SCTP_STATE_SHUTDOWN_ACK_SENT and SCTP_STATE_SHUTDOWN_SENT
      states, but they are not really impacted because we disable Heartbeats in those
      states.

      powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF case · 4d9aac39
      Guilherme G. Piccoli authored
      Since commit 1851617c ("PCI/MSI: Disable MSI at enumeration even if
      kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the
      disable of MSI/MSI-X interrupts isn't being done at PCI probe time, as
      the logic responsible for this was moved in the aforementioned commit
      from pci_device_add() to pci_setup_device(). The latter function is not
      reachable on PowerPC pseries platform during Open Firmware PCI probing
      time.
      
      This exhibits as drivers not being able to enable MSI, eg:
      
        bnx2x 0000:01:00.0: no msix capability found
      
      This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X
      during PCI probe time on pSeries platform.

      PCI: Make pci_msi_setup_pci_dev() non-static for use by arch code · 22b6839b
      Guilherme G. Piccoli authored
      Commit 1851617c ("PCI/MSI: Disable MSI at enumeration even if kernel
      doesn't support MSI") changed the location of the code that initialises
      dev->msi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI
      probe time in devices that have this flag set. It moved the code from
      pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(),
      called by pci_setup_device().
      
      The pseries PCI probing code does not call pci_setup_device(), so since
      the aforementioned commit the function pci_msi_setup_pci_dev() is not
      called and MSI/MSI-X interrupts are left enabled. Additionally because
      dev->msi_cap/msix_cap are not initialised no driver can ever enable
      MSI/MSI-X.
      
      To fix this, the pseries PCI probe should manually call
      pci_msi_setup_pci_dev(), so this patch makes it non-static.

      WANG Cong authored
      In commit 1e052be6 ("net_sched: destroy proto tp when all filters are gone")
      I added a check in u32_destroy() to see if all real filters are gone
      for each tp, however, that is only done for root_ht, same is needed
      for others.
      
      This can be reproduced by the following tc commands:
      
      tc filter add dev eth0 parent 1:0 prio 5 handle 15: protocol ip u32 divisor 256
      tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:2 u32
