These patches add support for several privileged RISC-V extensions, including Sm/scsrind, Smrnmi, Ssccptr, Sscounterenw, Sstvala, Sstvecd, and Ssu64xl.
The CSRs definition in Binutils part, and gcc part just let the compiler and user know these extensions are supported. Jiawei (7): RISC-V: Support Sm/scsrind extensions.
