      drm-intel-next-2015-11-20-rebased:
      4 weeks because of my vacation, so a bit more:
      - final bits of the typesafe register mmio functions (Ville)
      - power domain fix for hdmi detection (Imre)
      - tons of fixes and improvements to the psr code (Rodrigo)
      - refactoring of the dp detection code (Ander)
      - complete rework of the dmc loader and dc5/dc6 handling (Imre, Patrik and
        others)
      - dp compliance improvements from Shubhangi Shrivastava
      - stop_machine hack from Chris to fix corruptions when updating GTT ptes on bsw
      - lots of fifo underrun fixes from Ville
      - big pile of fbc fixes and improvements from Paulo
      - fix fbdev failures paths (Tvrtko and Lukas Wunner)

      Here's the first drm-misc pull, with really mostly misc stuff all over.
      Somewhat invasive is only Ville's change to mark the arg struct for
      fb_create const - that might conflict with a new driver pull. So better to
      get in fast.

      target: fix COMPARE_AND_WRITE non zero SGL offset data corruption · d94e5a61
      Jan Engelhardt authored
      target_core_sbc's compare_and_write functionality suffers from taking
      data at the wrong memory location when writing a CAW request to disk
      when a SGL offset is non-zero.
      
      This can happen with loopback and vhost-scsi fabric drivers when
      SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
      SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.
      
      Given the following sample LIO subtopology,
      
      % targetcli ls /loopback/
      o- loopback ................................. [1 Target]
        o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3]
          o- luns ................................... [2 LUNs]
            o- lun0 ................ [iblock/ram0 (/dev/ram0)]
            o- lun1 ................ [iblock/ram1 (/dev/ram1)]
      % lsscsi -g
      [3:0:1:0]    disk    LIO-ORG  IBLOCK           4.0   /dev/sdc   /dev/sg3
      [3:0:1:1]    disk    LIO-ORG  IBLOCK           4.0   /dev/sdd   /dev/sg4
      
      the following bug can be observed in Linux 4.3 and 4.4~rc1:
      
      % perl -e 'print chr$_ for 0..255,reverse 0..255' >rand
      % perl -e 'print "\0" x 512' >zero
      % cat rand >/dev/sdd
      % sg_compare_and_write -i rand -D zero --lba 0 /dev/sdd
      % sg_compare_and_write -i zero -D rand --lba 0 /dev/sdd
      Miscompare reported
      % hexdump -Cn 512 /dev/sdd
      00000000  0f 0e 0d 0c 0b 0a 09 08  07 06 05 04 03 02 01 00
      00000010  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
      *
      00000200
      
      Rather than writing all-zeroes as instructed with the -D file, it
      corrupts the data in the sector by splicing some of the original
      bytes in. The page of the first entry of cmd->t_data_sg includes the
      CDB, and sg->offset is set to a position past the CDB. I presume that
      sg->offset is also the right choice to use for subsequent sglist
      members.
