      Merge tag 'for-5.10/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
      
      Pull device mapper fixes from Mike Snitzer:
      
       - Fix DM's bio splitting changes that were made during v5.9. This
         restores splitting in terms of varied per-target ti->max_io_len
         rather than use block core's single stacked 'chunk_sectors' limit.
      
       - Like DM crypt, update DM integrity to not use crypto drivers that
         have CRYPTO_ALG_ALLOCATES_MEMORY set.
      
       - Fix DM writecache target's argument parsing and status display.
      
       - Remove needless BUG() from dm writecache's persistent_memory_claim()
      
       - Remove old gcc workaround in DM cache target's block_div() for ARM
         link errors now that gcc >= 4.9 is required.
      
       - Fix RCU locking in dm_blk_report_zones and dm_dax_zero_page_range.
      
       - Remove old, and now frowned upon, BUG_ON(in_interrupt()) in
         dm_table_event().
      
       - Remove invalid sparse annotations from dm_prepare_ioctl() and
         dm_unprepare_ioctl().

      dm: fix IO splitting · 3ee16db3
      Mike Snitzer authored
      Commit 882ec4e6 ("dm table: stack 'chunk_sectors' limit to account
      for target-specific splitting") caused a couple regressions:
      1) Using lcm_not_zero() when stacking chunk_sectors was a bug because
         chunk_sectors must reflect the most limited of all devices in the
         IO stack.
      2) DM targets that set max_io_len but that do _not_ provide an
         .iterate_devices method no longer had there IO split properly.
      
      And commit 5091cdec ("dm: change max_io_len() to use
      blk_max_size_offset()") also caused a regression where DM no longer
      supported varied (per target) IO splitting. The implication being the
      potential for severely reduced performance for IO stacks that use a DM
      target like dm-cache to hide performance limitations of a slower
      device (e.g. one that requires 4K IO splitting).
      
      Coming full circle: Fix all these issues by discontinuing stacking
      chunk_sectors up using ti->max_io_len in dm_calculate_queue_limits(),
      add optional chunk_sectors override argument to blk_max_size_offset()
      and update DM's max_io_len() to pass ti->max_io_len to its
      blk_max_size_offset() call.
      
      Passing in an optional chunk_sectors override to blk_max_size_offset()
      allows for code reuse of block's centralized calculation for max IO
      size based on provided offset and split boundary.
      
      Fixes: 882ec4e6 ("dm table: stack 'chunk_sectors' limit to account for target-specific splitting")
      Fixes: 5091cdec

       "This week's regular fixes.
      
        i915 has fixes for a few races, use-after-free, and gpu hangs. Tegra
        just has some minor fixes that I didn't see much point in hanging on
        to. The nouveau fix is for all pre-nv50 cards and was reported a few
        times. Otherwise it's just some amdgpu, and a few misc fixes.

         - SMU11 manual fan fix

         - Retain default context state across shrinking (Venkata)
         - Limit frequency drop to RPe on parking (Chris)
         - Return earlier from intel_modeset_init() without display (Jani)
         - Defer initial modeset until after GGTT is initialized (Chris)
      
        nouveau:
         - pre-nv50 regression fix

      One bridge fix for OMAP, one for a race condition in a panel, two for
      uninitialized variables in rockchip and nouveau, and two fixes for mxsfb
      to fix a regression with modifiers and a fix for a fence synchronization
      issue.
