[PATCH] i383 numa: fix numaq/summit apicid conflict
This allows numaq to properly align cpus to their given node during boot. Pass logical apicid to apicid_to_node and allow the summit sub-arch to use physical apicid (hard_smp_processor_id()). Tested against numaq and summit based systems with no issues. Signed-off-by: Keith Mannthey <kmannth@us.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
