Merge patch series "riscv: alternative-macros.h cleanups"
Andrew Jones <ajones@ventanamicro.com> says: This series is a collection of cleanups for alternative-macros.h with the main motivation being that adding new ALTERNATIVE_3, ALTERNATIVE_4, ... will be possible without lots of bloat. * b4-shazam-merge: riscv: Don't duplicate _ALTERNATIVE_CFG* macros riscv: alternatives: Drop the underscores from the assembly macro names riscv: alternatives: Don't name unused macro parameters riscv: Don't duplicate __ALTERNATIVE_CFG in __ALTERNATIVE_CFG_2 Link: https://lore.kernel.org/r/20221129150053.50464-1-ajones@ventanamicro.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
