Bugzilla: 918907
218e99
Upstream status: not applicable
218e99
  (pc-0.12 already have CPUID_APIC enabled for almost 4 years)
218e99
Brew build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=6290888
218e99
218e99
QEMU v0.13 and newer has CPUID_APIC set on pentium, pentium2, and
218e99
pentium3 CPU models[1], but v0.12 (and RHEL-6) don't have it. We need to
218e99
disable the flag on pc_init_rhel650() to keep compatibility.
