Define boot_cpu_id in single-processor kernels as well. This is to support architectures which can boot on other than CPU0. Sam Ravnborg has written the cleanup parts by extracting boot_cpu_id from smp_32.c into setup_32.c and cleaned up sun4d_irq.c. boot_cpu_id was initialized before BSS was cleared in sun4c_continue_boot, instead boot_cpu_id is set to 0xff to avoid BSS. If boot_cpu_id is untouched (0xff) by bootup code it will be overwritten to 0. boot_cpu_id4 is automatically calculated in common code.
