The ISA and ABI pairs supported as follows: These really ought to be proper sentences and document the extra kernel version requirement, so how about (pinching from the original RV64 note): * Support for the RISC-V ISA running on Linux has been expanded to run on 32-bit hardware. This requires at least Linux 5.4 and is supported for the following ISA and ABI pairs: ? Maciej
