I have fixed the warnings in my latest KGDB patchset and sent it out, but the merged KGDB patchset is not my latest version. I have sent a patch set to complement the missing ports, and I think these warnings would disappear after this patch has been accepted and merged. Here is the patch to fix this warning: http://lists.infradead.org/pipermail/linux-riscv/2020-June/000660.html
Thank you Vincent, let's drop my hacky patch then.
