If CONFIG_SMP=n, <linux/smp.h> does not include <asm/smp.h>, causing:
drivers/cpufreq/ppc-corenet-cpufreq.c: In function 'corenet_cpufreq_cpu_init': drivers/cpufreq/ppc-corenet-cpufreq.c:173:3: error: implicit declaration of function 'get_hard_smp_processor_id' [-Werror=implicit-function-declaration]
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Seen with e.g. corenet64_smp_defconfig + CONFIG_CPU_FREQ=y, CONFIG_PPC_CORENET_CPUFREQ=y, CONFIG_SMP=n
v2: - Add comment for #include directive, as requested by Viresh --- drivers/cpufreq/ppc-corenet-cpufreq.c | 2 ++ 1 file changed, 2 insertions(+)
