函数名称：load_ucode_ap

函数原型：void load_ucode_ap(void)

返回类型：void

参数：无

210  如果check_loader_disabled_ap()则返回
213  cpuid_1_eax等于Native CPUID functions returning a single datum.
216  当:In early loading microcode phase on BSP, boot_cpu_data is not set up yet.* x86_cpuid_vendor() gets vendor id for BSP.* In 32 bit AP case, accessing boot_cpu_data needs linear address. To simplify恒等于X86_VENDOR_INTEL
217  如果x86_family(cpuid_1_eax)大于等于6则load_ucode_intel_ap()
219  退出
220  当:In early loading microcode phase on BSP, boot_cpu_data is not set up yet.* x86_cpuid_vendor() gets vendor id for BSP.* In 32 bit AP case, accessing boot_cpu_data needs linear address. To simplify恒等于X86_VENDOR_AMD
221  如果x86_family(cpuid_1_eax)大于等于0x10则load_ucode_amd_ap(cpuid_1_eax)
223  退出
224  默认
