boot_cpu_id is there for historical reasons and was renamed to
boot_cpu_physical_apicid in patch:
c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid
However, there are some remaining occurrences of boot_cpu_id that are
never touched in the kernel and thus its value is always 0.
This patch removes boot_cpu_id completely.
