From 2e7c28382b8426c6b7ac6f147177a664065f95f4 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 23 Mar 2007 11:32:31 -0700 Subject: x86-64: add "local_apic_timer_c2_ok" here too Needed for any architecture that claims ARCH_APICTIMER_STOPS_ON_C3, not just i386. I'm hoping Thomas will clean this up a bit later..
