Hi again,

This is version two of the patches I posted yesterday:

  v1: https://lkml.kernel.org/r/20190820154549.17018-1-will@kernel.org

Changes since then include:

  * Fix 'ats_enabled' checking when enabling ATS
  * Remove redundant 'dev_is_pci()' calls
  * Remove bool bitfield
  * Add patch temporarily disabling ATS detection for -stable
  * Issue ATC invalidation even when non-leaf
  * Elide invalidation/SYNC for zero-sized address ranges
  * Shuffle the patches round a bit

Thanks,

Will
