From b8ba5f10c5956d2b297766fda8f4f5ab8ad1e2cc Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Wed, 30 Apr 2008 12:39:05 -0300 Subject: [PATCH] x86: KVM geust: make setup_secondary_clock definition dependent on local apic Since the pv_apic_ops are only present if CONFIG_X86_LOCAL_APIC is compiled in, kvmclock failed to build without this option. This patch fixes this.
