boot_cpu_physical_apicid is written in random places and in the last consequence filled with the APIC ID read from the local APIC. That causes it to have inconsistent state when the MPTABLE is broken. As a consequence tons of moronic checks are sprinkled all over the place. Consolidate the code and read it exactly once when either X2APIC mode is detected early or when the APIC mapping is established.
