参数：

类型参数名称
struct cpuinfo_x86 *c
417  如果CPU family 左移8位按位或x86_model左移4位按位或x86_stepping的值小于0x633则clear_cpu_cap(c, SYSENTER/SYSEXIT )
425  如果forcepae则
426  打印警告信息("PAE forced!\n")
427  set_cpu_cap(c, Physical Address Extensions )
428  add_taint(TAINT_CPU_OUT_OF_SPEC, LOCKDEP_NOW_UNRELIABLE)
435  如果CPU family 恒等于15且x86_model恒等于1且x86_stepping恒等于1则
436  如果Set @bit in a MSR @msr.* Retval:* < 0: An error was encountered.* = 0: Bit was already set.* > 0: Hardware accepted the MSR write.大于0则
438  打印信息("CPU: C0 stepping P4 Xeon detected.\n")
439  打印信息("CPU: Disabling hardware prefetching (Erratum 037)\n")
449  如果boot_cpu_has(Onboard APIC )且CPU family 左移8位按位或x86_model左移4位的值恒等于0x520且x86_stepping小于0x6或x86_stepping恒等于0xb的值则set_cpu_bug(c, Bad local APIC aka 11AP )
472  intel_smp_check(c)
