2144  mp_lapic_addr等于address
2146  如果非x2apic_mode则
2147  Some hardware wants to get fixmapped without caching.(FIX_APIC_BASE, address)
2148  Define the default level of output to be very little* This can be turned up by using apic=verbose for more* information and apic=debug for _lots_ of information.* apic_verbosity is defined in apic.c(APIC_VERBOSE, "mapped APIC to %16lx (%16lx)\n", APIC_BASE, address)
2151  如果Processor that is doing the boot up 恒等于负1U则
2152  Processor that is doing the boot up 等于read_apic_id()
