NOTE: The patch will not be queued to stable trees until it is upstream.

How should we proceed with this patch?

I think it's fine to leave this out of 4.19, as I doubt we have anyone using it on RISC-V systems as there were some pretty major kernel bugs back then.

The PLIC driver was merged in 4.19, so the older kernels are obvious non-starters.
