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

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
1331  Max extended CPUID function supported: 等于0
1333  如果非Probe for the CPUID instruction 则identify_cpu_without_cpuid(c)
1337  如果非Probe for the CPUID instruction 则返回
1340  cpu_detect(c)
1342  get_cpu_vendor(c)
1344  get_cpu_cap(c)
1346  get_cpu_address_sizes(c)
1348  如果Maximum supported CPUID level, -1=no CPUID: 大于等于0x00000001则
1349  initial_apicid等于cpuid_ebx(1)右移24位按位与0xFF
1354  apicid等于initial_apicid
