This fix was in the v9 of "riscv: Add GENERIC_ENTRY support and related
features" [1] but was dropped in v10 [2] with the prospect that it would
be submitted separately. That seems to have not happened so I am
submitting it now. I want to silence the riscv warnings when using W=1.
With this patch applied to riscv/for-next, I no longer see any warnings
for riscv.
