From 1a8880a14270814dae0d226a2ad065d30587e60a Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Fri, 20 May 2011 17:51:20 -0700 Subject: [PATCH] x86, apic: Make apic drivers static Apic probe now looks at the apic drivers listed in the .apicdrivers section. Remove apic_probe[] and make each apic driver static.
