[Robbin Ehn]

> Hi, please consider.
> 
> As we have kernel bugs to work around in RISC-V, we need a more detailed check.
> See:
> https://github.com/openjdk/jdk/pull/23256
> 
> I updated the naming to align with Linux (major, patch, sub):
> https://github.com/torvalds/linux/blob/bc8198dc7ebc492ec3e9fa1617dcdfbe98e73b17/Makefile#L1313
