函数名称：early_init_zhaoxin

函数原型：static void early_init_zhaoxin(struct cpuinfo_x86 *c)

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
67  如果CPU family 大于等于0x6则set_cpu_cap(c, TSC ticks at a constant rate )
70  set_cpu_cap(c, "" sysenter in IA32 userspace )
72  如果x86_power按位与1左移8位则
73  set_cpu_cap(c, TSC ticks at a constant rate )
74  set_cpu_cap(c, TSC does not stop in C states )
77  如果Maximum supported CPUID level, -1=no CPUID: 大于等于0x00000001则
80  cpuid(0x00000001, & eax, & ebx, & ecx, & edx)
86  如果edx按位与1U左移28位则CPUID returned core id bits: 等于get_count_order((ebx >> 16) & 0xff)
