Subject: [PATCH 2/2] target-i386: Copy cpu64-rhel6 definition into qemu64
RH-Author: Eduardo Habkost <ehabkost@redhat.com>

O-Subject: [RHEL7 qemu-kvm PATCH 2/2] target-i386: Copy cpu64-rhel6 definition into qemu64
Bugzilla: 1080170
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
RH-Acked-by: Alex Williamson <alex.williamson@redhat.com>
RH-Acked-by: Bandan Das <bsd@redhat.com>
Bugzilla: 1078607
Brew scratch build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=7250917
Upstream status: not applicable
The CPUID data from cpu64-rhel6 is a better default than qemu64. Among
other things, this fixes MSI problems on 32-bit Windows guests.
