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

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
776  v等于x86_vendor_id
779  以i小于X86_VENDOR_NUM循环
780  如果非cpu_devs[i]则退出

787  this_cpu等于cpu_devs[i]
788  CPU vendor 等于c_x86_vendor
789  返回
794  pr_err_once("CPU: vendor_id '%s' unknown, using generic init.\nCPU: Your system may be unstable.\n", v)
796  CPU vendor 等于X86_VENDOR_UNKNOWN
797  this_cpu等于default_cpu
