We need your Signed-off-by here. However, I see that the upstreaming
process hasn't really made progress, and especially you're pointing
that binaries built with this elf2flt RISC-V support fail with recent
kernels.

Do you have some news about fixing this? It's a bit annoying to merge
something that doesn't work with recent kernels.
