From: Keith Mannthey Date: Wed, 4 Oct 2006 01:25:52 +0000 (-0700) Subject: [PATCH] i383 numa: fix numaq/summit apicid conflict X-Git-Tag: v2.6.19-rc1~164 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=78b656b8bf933101b42409b4492734b23427bfc3;p=linux-2.6 [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.
