函数名称：x86_match_cpu - match current CPU again an array of x86_cpu_ids*@match: Pointer to array of x86_cpu_ids. Last entry terminated with* {}.* Return the entry if the current CPU matches the entries in the* passed x86_cpu_id match table

函数原型：const struct x86_cpu_id *x86_match_cpu(const struct x86_cpu_id *match)

返回类型：struct x86_cpu_id

参数：

类型参数名称
const struct x86_cpu_id *match
35  c等于common cpu data for all cpus
37  以vendor按位或family按位或model按位或 bit index 循环
38  如果vendor不等于X86_VENDOR_ANY且CPU vendor 不等于vendor则继续下一循环
40  如果family不等于X86_FAMILY_ANY且CPU family 不等于family则继续下一循环
42  如果model不等于X86_MODEL_ANY且x86_model不等于model则继续下一循环
44  如果 bit index 不等于Same as FPU, you can't test for that 且非cpu_has(c, bit index )则继续下一循环
46  返回:m
48  返回:NULL
