Move phys_cpu_num and pcpu_active_bitmap to common, which could be only accessed by interfaces provided by smp.h. v2->v3: 1. move ALL_CPUS_MASK/AP_MASK to common cpu.h v1->v2: 1. preserve phys_cpu_num in x86 but implement arch_get_num_available_cpus() to provide interface for common code to access. 2. change function name test_xx to check_xx Tracked-On: #8801 Signed-off-by: hangliu1 <hang1.liu@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com> Reviewed-by: Liu, Yifan1 <yifan1.liu@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
