I think this needs some punctuation as it is pretty hard to read. Slightly adjusted, hopefully it keeps the same message: Now that we track the type of the stored register state separately to what is active in the task, it is valid to have the FPSIMD register state stored while in streaming mode. Remove the special case handling for SME when setting FPSIMD register state.
