返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
672  n等于Max extended CPUID function supported:
674  如果n大于等于0x80000005则
675  cpuid(0x80000005, & dummy, & ebx, & ecx, & edx)
676  KB - valid for CPUS which support this call: 等于ecx右移24位的值加edx右移24位的值
679  Number of 4K pages in DTLB/ITLB combined(in pages): 等于0
683  如果n小于0x80000006则返回
686  cpuid(0x80000006, & dummy, & ebx, & ecx, & edx)
687  l2size等于ecx右移16位
690  Number of 4K pages in DTLB/ITLB combined(in pages): 加等于ebx右移16位按位与0xfff的值加ebx按位与0xfff的值
704  KB - valid for CPUS which support this call: 等于l2size
