If anyone has any objections, please let me know. ------------------ From: Aurelien Jarno [ Upstream commit 55b1276ef9c1c27e8a2b2c5e8ef0515b5ad0332c ] The __vstate_csr_save() inline assembly declares vcsr as an output operand while the assembly only writes vstart, vtype, and vl. Remove it as it is later saved by the C code.
