That is not what this commit id is :(

Please fix this up and be more careful.

That's the exact commit, the original upstream commit was named as "MIPS: Add support for ZSTD-compressed kernels", which contains the memmove() definition so the upstream / 5.10 LTS kernel is fine.

But for 5.4 LTS, we shouldn't backport the whole patch since only memmove() part is needed in order to fix the build regression...

Thanks, Gao Xiang

thanks,
