Author: gibbs Date: Fri Sep 27 15:17:28 2013 New Revision: 255913 URL: http://svnweb.freebsd.org/changeset/base/255913 Log: sys/x86/xen/hvm.c: Set cpu_ops correctly for Xen hypervisors lacking the vector callback feature. Set preliminary Xen cpu_ops settings during early HVM initialization. The old location raced with the startup of APs.
