The false negatives always throw me off. The errors are also offset by
one patch. This was actually introduced in the following patch "riscv:
Introduce vendor variants of extension helpers" because I accidentally
fixed this issue in the patch "riscv: cpufeature: Extract common
elements from extension checking" instead of the one it was introduced
in.
