Merge patch series "riscv: Use Kconfig to set unaligned access speed"

Charlie Jenkins <charlie@rivosinc.com> says: If the hardware unaligned access speed is known at compile time, it is possible to avoid running the unaligned access speed probe to speedup boot-time. * b4-shazam-merge: riscv: Set unaligned access speed at compile time riscv: Decouple emulated unaligned accesses from access speed riscv: Only check online cpus for emulated accesses riscv: lib: Introduce has_fast_unaligned_access() Link: https://lore.kernel.org/r/20240308-disable_misaligned_probe_config-v9-0-a388770ba0ce@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
