Hi,

This v2 drops a patch from v1 and fixes the chunk_sectprs check added to
blk_stack_limits to convert chubk_sectors to bytes before comparing with
physical_block_size.

Jens, please feel free to pick up patches 1 and 2.

DM patches 3 and 4 are provided just to give context for how DM will be
updated to use chunk_sectors.

Mike Snitzer (4):
  block: use lcm_not_zero() when stacking chunk_sectors
  block: allow 'chunk_sectors' to be non-power-of-2
  dm table: stack 'chunk_sectors' limit to account for target-specific splitting
  dm: unconditionally call blk_queue_split() in dm_process_bio()
