From 4c321ff8a01a95badf5d5403d80ca4e0ab07fce7 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Jan 2011 14:37:30 +0100 Subject: x86: Replace cpu_2_logical_apicid[] with early percpu variable Unlike x86_64, on x86_32, the mapping from cpu to logical apicid may vary depending on apic in use. cpu_2_logical_apicid[] array is used for this mapping. Replace it with early percpu variable x86_cpu_to_logical_apicid to make it better aligned with other mappings.
