This problem is unrelated to this patch, you can see below it is from 2021-03-09, and it isn't even introduced by that commit but only by the fact that it uses _GLOBAL() which has existed for years.
Anyway, there is already a patch to fix it at https://patchwork.ozlabs.org/project/linuxppc-dev/patch/68932ec2ba6b868d35006b96e90f0890f3da3c05.1638273868.git.christophe.leroy@csgroup.eu/
