Hi all,

This is version two of the patches I previously posted here:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2019-March/636331.html

Changes since v1 include:

  * Dropped the first two patches, since they have been merged as fixed
  * Fixed break dispatching to work with comment ranges (required by KASAN)
  * Based on 5.1-rc3

I plan to queue these up for 5.2, pending any issues.

Will
