Yes, we need to backport this patchset to all the current supported kernel. Since most of the supported kernel contains the whole RFI infra structure, I do not expect it to be hard. If you need help, I can find someone to help on the backport.
Regarding the problem you are facing, I talked to the powerpc maintainer (Michael Ellerman) and he suggested squashing the warning using something as the code below. He will be also sending the patch upstream.
