      Merge tag 'for-4.12/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
      
      Pull device mapper fixes from Mike Snitzer:
      
       - a couple DM thin provisioning fixes
      
       - a few request-based DM and DM multipath fixes for issues that were
         made when merging Christoph's changes with Bart's changes for 4.12
      
       - a DM bufio unsigned overflow fix
      
       - a couple pure fixes for the DM cache target.
      
       - various very small tweaks to the DM cache target that enable
         considerable speed improvements in the face of continuous IO. Given
         that the cache target was significantly reworked for 4.12 I see no
         reason to sit on these advances until 4.13 considering the favorable
         results associated with such minimalist tweaks.

        dm cache: handle kmalloc failure allocating background_tracker struct

        dm cache policy smq: don't do any writebacks unless IDLE
        dm cache: simplify the IDLE vs BUSY state calculation
        dm cache: track all IO to the cache rather than just the origin device's IO
        dm cache policy smq: stop preemptively demoting blocks
        dm cache policy smq: put newly promoted entries at the top of the multiqueue
        dm cache policy smq: be more aggressive about triggering a writeback
        dm cache policy smq: only demote entries in bottom half of the clean multiqueue
        dm cache: fix incorrect 'idle_time' reset in IO tracker

      dm cache: handle kmalloc failure allocating background_tracker struct · 7e1b9521
      Colin Ian King authored
      Currently there is no kmalloc failure check on the allocation of
      the background_tracker struct in btracker_create(), and so a NULL return
      will lead to a NULL pointer dereference.  Add a NULL check.
      
      Detected by CoverityScan, CID#1416587 ("Dereference null return value")
      
      Fixes: b29d4986 ("dm cache: significant rework to leverage dm-bio-prison-v2")

      i2c: xgene: Set ACPI_COMPANION_I2C · 83345d51
      Tin Huynh authored
      With ACPI, i2c-core requires ACPI companion to be set in order for it
      to create slave device.
      This patch sets the ACPI companion accordingly.
