Description

Booting on a Westmere system, I was greeted with error messages about MCA support. I suspect this is a regression introduced by 10277. The problem is that the APIC ID space isn't uniform, which the changes were somewhat relying on. Instead we need to use the number of required bits to cover the space as was previously used.
