Mike Travis 71fff5e6ca x86: convert cpu_to_apicid to be a per cpu variable ... This patch converts the x86_cpu_to_apicid array to be a per cpu variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. MP_processor_info() is one of the functions that require access to the x86_cpu_to_apicid array before the per_cpu data area is setup. For this case, a pointer to the __initdata array is initialized in setup_arch() and removed in smp_prepare_cpus() after the per_cpu data area is initialized. A second change is included to change the initial array value of ARCH i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.
