      vfio: Fix PCI INTx disable consistency · 899649b7
      Alex Williamson authored
      
      
      The virq_disabled flag tracks the userspace view of INTx masking
      across interrupt mode changes, but we're not consistently applying
      this to the interrupt and masking handler notion of the device.
      Currently if the user sets DisINTx while in MSI or MSIX mode, then
      returns to INTx mode (ex. rebooting a qemu guest), the hardware has
      DisINTx+, but the management of INTx thinks it's enabled, making it
      impossible to actually clear DisINTx.  Fix this by updating the
      handler state when INTx is re-enabled.

      vfio: Move PCI INTx eventfd setting earlier · 9dbdfd23
      Alex Williamson authored
      
      
      We need to be ready to recieve an interrupt as soon as we call
      request_irq, so our eventfd context setting needs to be moved
      earlier.  Without this, an interrupt from our device or one
      sharing the interrupt line can pass a NULL into eventfd_signal
      and oops.

      vfio: Fix PCI mmap after b3b9c293 · 34002f54
      Alex Williamson authored
      Our mmap path mistakely relied on vma->vm_pgoff to get set in
      remap_pfn_range.  After b3b9c293
      
      , that path only applies to
      copy-on-write mappings.  Set it in our own code.

      Pull pwm changes from Thierry Reding:
       "All legacy PWM providers have now been moved to the PWM subsystem.
        The plan for 3.8 is to adapt all board files to provide a lookup table
        for PWM devices in order to get rid of the global namespace.
        Subsequently, users of the legacy pwm_request() and pwm_free()
        functions can be migrated to the new pwm_get() and pwm_put()
        functions.  Once this has been completed, the legacy API and the
        compatibility code in the core can be removed.
      
        In addition to the above, these changes also add support for
        configuring the polarity of a PWM signal (currently only supported on
        ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
        Managed functions to obtain and release a PWM device (devm_pwm_get()
        and devm_pwm_put()) have been added and the pwm-backlight driver has
        been updated to use them.  If the PWM subsystem hasn't been enabled,
        dummy functions are provided that allow the subsystem to safely
        compile out.
      
        Some common checks on input parameters have been moved to the core and
        removed from the drivers.  Finally, a small fix corrects the
        description of the PWM specifier's second cell in the device tree
        representation."

      Pull scsi target updates from Nicholas Bellinger:
       "Things have been calm for the most part with no new fabric drivers in
        flight for v3.7 (we're up to eight now !), so this update is primarily
        focused on addressing a few long-standing items within target-core and
        iscsi-target fabric code.
      
        The highlights include:
      
         - target: Simplify fabric sense data length handling (roland)
         - qla2xxx: Fix endianness of task management response code (roland)
         - target: fix truncation of mode data, support zero allocation length
           (paolo)
         - target: Properly support zero-length commands in normal processing
           path (paolo)
         - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
           PDU (ronnie + nab)
         - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
           demo-mode (ronnie + nab)
         - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
           hch)
         - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
           initiator MDRSL declaration (nab)
         - target: Add target_submit_cmd_map_sgls for SGL fabric memory
           passthrough (nab + hch)
         - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
           nab)
         - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
           + hch)
      
        The last series for adding a new target_submit_cmd_map_sgls() fabric
        caller (as requested by hch) that accepts pre-allocated SGL memory
        (using existing logic), along with converting tcm_loop + tcm_vhost has
        only been in -next for the last days, but has gotten enough review
        +testing and is clear enough a mechanical change that I think it's
        reasonable to merge for -rc1 code.
      
        Thanks again to everyone who contributed this round! Extra special
        thanks to Roland (PureStorage) for tracking down the qla2xxx target
        TMR response code endian issue, and to Paolo (Redhat) for resolving
        the long standing zero-length CDB issues within target-core between

       3) Now that tunnels support GRO, we have to be more careful in
          skb_gro_reset_offset() otherwise we OOPS, from Eric Dumazet.
      
       4) We can end up processing packets for VLANs we aren't actually
          configured to be on, fix from Florian Zumbiehl.
      
       5) Fix routing cache removal regression in redirects and IPVS.  The
          core issue on the IPVS side is that it wants to rewrite who the
          nexthop is and we have to explicitly accomodate that case.  From
          Julian Anastasov.
      
       6) Error code return fixes all over the networking drivers from Peter
          Senna Tschudin.
      
       7) Fix routing cache removal regressions in IPSEC, from Steffen
          Klassert.
      
       8) Fix deadlock in RDS during pings, from Jeff Liu.
      
       9) Neighbour packet queue can trigger skb_under_panic() because we do
          not reset the network header of the SKB in the right spot.  From
          Ramesh Nagappa.
