cpuidle: riscv: support non-SMP config
Add <asm/smp.h> for cpuid_to_hartid_map etc. This is needed for both SMP and non-SMP builds, but not having it causes a build error for non-SMP: drivers/cpuidle/cpuidle-riscv-sbi.c: In function 'sbi_cpuidle_init_cpu': drivers/cpuidle/cpuidle-riscv-sbi.c:350:26: error: implicit declaration of function 'cpuid_to_hartid_map' [-Werror=implicit-function-declaration] Fixes: 6abf32f1d9c5 ("cpuidle: Add RISC-V SBI CPU idle driver") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kernel test robot <lkp@intel.com> Reviewed-by: Anup Patel <anup@brainfault.org> Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
