Hi all,

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

  v1: http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@arm.com
  v2: http://lkml.kernel.org/r/1538478363-16255-1-git-send-email-will.deacon@arm.com
  v3: http://lkml.kernel.org/r/1539188584-15819-1-git-send-email-will.deacon@arm.com

The only change since v3 is a rebase onto v4.20-rc3, which was automatic.

I would appreciate a review of patch 4. Sean, please could you take a
quick look?

Thanks,

Will
