      ALSA: hda - fix a problem for lineout on a Dell AIO machine · ce3dcfdb
      Hui Wang authored
      commit 2f726aec upstream.
      
      On this Dell AIO machine, the lineout jack does not work.
      
      We found the pin 0x1a is assigned to lineout on this machine, and in
      the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
      heaset-set mic problem for this machine, this fixup will redefine
      the pin 0x1a to headphone-mic, as a result the lineout doesn't
      work anymore.
      
      After consulting with Dell, they told us this machine doesn't support
      microphone via headset jack, so we add a new fixup which only defines
      the pin 0x18 as the headset-mic.
      
      [rearranged the fixup insertion position by tiwai in order to make the
       merge with other branches easier -- tiwai]

      ALSA: seq: Fix race during FIFO resize · a90d7447
      Takashi Iwai authored
      commit 2d7d5400 upstream.
      
      When a new event is queued while processing to resize the FIFO in
      snd_seq_fifo_clear(), it may lead to a use-after-free, as the old pool
      that is being queued gets removed.  For avoiding this race, we need to
      close the pool to be deleted and sync its usage before actually
      deleting it.
      
      The issue was spotted by syzkaller.

      scsi: libsas: fix ata xfer length · 75a03869
      John Garry authored
      commit 9702c67c upstream.
      
      The total ata xfer length may not be calculated properly, in that we do
      not use the proper method to get an sg element dma length.
      
      According to the code comment, sg_dma_len() should be used after
      dma_map_sg() is called.
      
      This issue was found by turning on the SMMUv3 in front of the hisi_sas
      controller in hip07. Multiple sg elements were being combined into a
      single element, but the original first element length was being use as
      the total xfer length.

      scsi: mpt3sas: fix hang on ata passthrough commands · 18639c4b
      James Bottomley authored
      commit ffb58456 upstream.
      
      mpt3sas has a firmware failure where it can only handle one pass through
      ATA command at a time.  If another comes in, contrary to the SAT
      standard, it will hang until the first one completes (causing long
      commands like secure erase to timeout).  The original fix was to block
      the device when an ATA command came in, but this caused a regression
      with
      
      commit 669f0441

          scsi: srp_transport: Move queuecommand() wait code to SCSI core
      
      So fix the original fix of the secure erase timeout by properly
      returning SAM_STAT_BUSY like the SAT recommends.  The original patch
      also had a concurrency problem since scsih_qcmd is lockless at that
      point (this is fixed by using atomic bitops to set and test the flag).
      
      [mkp: addressed feedback wrt. test_bit and fixed whitespace]

      xen/setup: Don't relocate p2m over existing one · 1eed198c
      Ross Lagerwall authored
      commit 7ecec850 upstream.
      
      When relocating the p2m, take special care not to relocate it so
      that is overlaps with the current location of the p2m/initrd. This is
      needed since the full extent of the current location is not marked as a
      reserved region in the e820.
      
      This was seen to happen to a dom0 with a large initial p2m and a small
      reserved region in the middle of the initial p2m.
