This has been sitting in patchwork for a while and I don't see a message
from either the reporter saying this was a good fix or from the selftests
maintainer that it has been picked up. I was gonna mark it "handled
elsewhere" but I noticed that this was only sent to the riscv
maintainers so we should probably harass Palmer today to pick this up?
