This patch will be the first user:
https://lore.kernel.org/lkml/1600666280-25651-1-git-send-email-yilun.xu@intel.com/

Krzysztof has since explained that this patch should have been on a separate
branch with a tag from me, so he can pull it in.

Everyone: I've reverted the patches. You've seen the comments, so
if one of the patches above is yours please address the comments and
resend them.

Thanks and sorry for messing this up ...
