      Pull drm fixes from Dave Airlie:
       "Intel: edid fixes, power consumption fix, s/r fix, haswell fix
      
        Radeon: BIOS loading fixes for UEFI and Thunderbolt machines, better
        MSAA validation, lockup timeout fixes, modesetting fixes
      
        One udl dpms fix, one vmwgfx fix, a couple of trivial core changes.
      
        There is an export added to ACPI as part of the radeon bios fixes.
      
        I've also included the fbcon flashing cursor vs deinit race fix, that
        seems the simplest place to start"
      
      Trivial conflict in drivers/video/console/fbcon.c due to me having
      already applied the fbcon flashing cursor vs deinit race fix, and Dave
      had added a comment in there too.

      Pull SCSI target fixes from Nicholas Bellinger:
       "The executive summary includes:
      
         - Post-merge review comments for tcm_vhost (MST + nab)
         - Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR)
         - Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou)
         - Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab)
         - Fix regression bug with handling of zero-length data CDBs (nab)
         - Fix vhost_scsi_target structure alignment (MST)
      
        Thanks again to everyone who contributed a bugfix patch, gave review
        feedback on tcm_vhost code, and/or reported a bug during their own
        testing over the last weeks.
      
        There is one other outstanding bug reported by Roland recently related
        to SCSI transfer length overflow handling, for which the current
        proposed bugfix has been left in queue pending further testing with
        other non iscsi-target based fabric drivers.
      
        As the patch is verified with loopback (local SGL memory from SCSI
        LLD) + tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric
        ports, it will be included into the next 3.6-rc-fixes PULL request."

        tcm_vhost: Fix vhost_scsi_target structure alignment
        target: Fix regression bug with handling of zero-length data CDBs
        target/pscsi: Fix bug with REPORT_LUNs handling for SCSI passthrough
        tcm_vhost: Change vhost_scsi_target->vhost_wwpn to char *
        target: fix NULL pointer dereference bug alloc_page() fails to get memory
        tcm_fc: Avoid debug overhead when not debugging

        rbd + cephfs), another one fixes problems with mounting a nonexistent

      task_work: add a scheduling point in task_work_run() · 88ec2789
      Eric Dumazet authored
      It seems commit 4a9d4b02 (switch fput to task_work_add) reintroduced
      the problem addressed in commit 944be0b2 (close_files(): add scheduling
      point)
      
      If a server process with a lot of files (say 2 million tcp sockets)
      is killed, we can spend a lot of time in task_work_run() and trigger
      a soft lockup.

      It's not critical (anymore) since another thread closing the file will block
      on ->device_lock before it gets to dropping the final reference, but it's
      definitely cleaner that way...

      vfio: get rid of vfio_device_put()/vfio_group_get_device* races · 90b1253e
      Al Viro authored
      we really need to make sure that dropping the last reference happens
      under the group->device_lock; otherwise a loop (under device_lock)
      might find vfio_device instance that is being freed right now, has
      already dropped the last reference and waits on device_lock to exclude
      the sucker from the list.
