[PATCH] x86-64: Don't assume APIC for boot processor has an APIC ID of zero
Originally from Stuart Hayes. When setting up the APIC for the Uniprocessor kernel don't assume the CPU has an APIC ID of zero. This fixes boot with the UP kernel on Dell PowerEdge 6800/6850 4way systems. Cc: Stuart.Hayes@dell.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
