Subject[PATCH] (2/5) Add ACPI hook, rename raw_phys_apicid to bios_cpu_apicid
Patch from James Cleverdon & John Stultz

This adds machine a type detection hook to the acpi code, and renames
raw_phys_apicid to bios_cpu_apicid (it's an array of apicid's to boot,
indexed by the bios' cpu numbering), and I other large machines will
need to use it later ... not necessarily using physical interrupts.
