      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.

      ACPI, PCI: Penalize legacy IRQ used by ACPI SCI · 5d0ddfeb
      Jiang Liu authored
      Nick Meier reported a regression with HyperV that "
        After rebooting the VM, the following messages are logged in syslog
        when trying to load the tulip driver:
          tulip: Linux Tulip drivers version 1.1.15 (Feb 27, 2007)
          tulip: 0000:00:0a.0: PCI INT A: failed to register GSI
          tulip: Cannot enable tulip board #0, aborting

        Errors occur in 3.19.0 kernel
        Works in 3.17 kernel.
      "
      
      According to the ACPI dump file posted by Nick at
      https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1440072
      
      The ACPI MADT table includes an interrupt source overridden entry for
      ACPI SCI:
      [236h 0566  1]                Subtable Type : 02 <Interrupt Source Override>
      [237h 0567  1]                       Length : 0A
      [238h 0568  1]                          Bus : 00
      [239h 0569  1]                       Source : 09
      [23Ah 0570  4]                    Interrupt : 00000009
      [23Eh 0574  2]        Flags (decoded below) : 000D
                                         Polarity : 1
                                     Trigger Mode : 3
      
      And in DSDT table, we have _PRT method to define PCI interrupts, which
      eventually goes to:
              Name (PRSA, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSB, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSC, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
              Name (PRSD, ResourceTemplate ()
              {
                  IRQ (Level, ActiveLow, Shared, )
                      {3,4,5,7,9,10,11,12,14,15}
              })
      
      According to the MADT and DSDT tables, IRQ 9 may be used for:
       1) ACPI SCI in level, high mode
       2) PCI legacy IRQ in level, low mode
      So there's a conflict in polarity setting for IRQ 9.
      
      Prior to commit cd68f6bd ("x86, irq, acpi: Get rid of special
      handling of GSI for ACPI SCI"), ACPI SCI is handled specially and
      there's no check for conflicts between ACPI SCI and PCI legagy IRQ.
      And it seems that the HyperV hypervisor doesn't make use of the
      polarity configuration in IOAPIC entry, so it just works.
      
      Commit cd68f6bd gets rid of the specially handling of ACPI SCI,
      and then the pin attribute checking code discloses the conflicts
      between ACPI SCI and PCI legacy IRQ on HyperV virtual machine,
      and rejects the request to assign IRQ9 to PCI devices.
      
      So penalize legacy IRQ used by ACPI SCI and mark it unusable if ACPI
      SCI attributes conflict with PCI IRQ attributes.

      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.
      
      Fixes: 1851617c ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI")

      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.
      
      Fixes: 1851617c ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI")

      usbnet: Get EVENT_NO_RUNTIME_PM bit before it is cleared · f50791ac
      Eugene Shatokhin authored
      It is needed to check EVENT_NO_RUNTIME_PM bit of dev->flags in
      usbnet_stop(), but its value should be read before it is cleared
      when dev->flags is set to 0.
      
      The problem was spotted and the fix was provided by
      Oliver Neukum <oneukum@suse.de>.

       "A single fix for status register read size in the nd_blk driver.
      
        The effect of getting the width of this register read wrong is that
        all I/O fails when the read returns non-zero.  Given the availability
        of ACPI 6 NFIT enabled platforms, this could reasonably wait to come
        in during the 4.3 merge window with a tag for 4.2-stable.  Otherwise,
        this makes the 4.2 kernel fully functional with devices that conform
        to the mmio-block-apertures defined in the ACPI 6 NFIT (NVDIMM
        Firmware Interface Table)"

      PCC is made selectable only by clients which use it. e.g. CPPC
      Default it to disabled so that it is not included accidentally on
      platforms which dont use it.

      cls_u32: complete the check for non-forced case in u32_destroy() · a6c1aea0
      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
      ht 15:2: match ip src 10.0.0.2 flowid 1:10
      tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:3 u32
      ht 15:2: match ip src 10.0.0.3 flowid 1:10
