[PATCH] Increase bus/apic limits on x86-64
This patch increases some hardcoded limits people have already run into or
plan to go towards eventually.
Increase max MP busses on x86-64. Needed for some machines. Suggested by
Andrew Chen and James Cleverdon.
MAX_IRQ_SOURCES kept at 256 for now, matching i386.
Increase MAX_IO_APICS to 32 following i386.
