Subject: [PATCH v2 0/4] Fix restricted DMA vs swiotlb_exit()

Hi again, folks,

This is version two of the patch series I posted yesterday:

  https://lore.kernel.org/r/20210719123054.6844-1-will@kernel.org

The only changes since v1 are:

  * Squash patches 2 and 3, amending the commit message accordingly
  * Add Reviewed-by and Tested-by tags from Christoph and Claire (thanks!)

I'd usually leave it a bit longer between postings, but since this fixes
issues with patches in -next I thought I'd spin a new version immediately.

Cheers,

Will
