From: Will Deacon

Hi all,

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

v1: http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@xxxxxxx
v2: http://lkml.kernel.org/r/1538478363-16255-1-git-send-email-will.deacon@xxxxxxx
v3: http://lkml.kernel.org/r/1539188584-15819-1-git-send-email-will.deacon@xxxxxxx
v4: http://lkml.kernel.org/r/1543252067-30831-1-git-send-email-will.deacon@xxxxxxx

The only difference from v4 is that I have added Sean's Reviewed-by to the
core change.

Andrew, please can you take this via your tree for 4.21?

Thanks,

Will
