Subject: [PATCH 08/25] pc: RHEL-6 don't have RDTSCP
RH-Author: Eduardo Habkost <ehabkost@redhat.com>
Message-id: <1379363997-11783-5-git-send-email-ehabkost@redhat.com>
Patchwork-id: 54399
O-Subject: [RHEL7 PATCH 4/4] pc: RHEL-6 don't have RDTSCP
Bugzilla: 918907
RH-Acked-by: Bandan Das <bsd@redhat.com>
RH-Acked-by: Markus Armbruster <armbru@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
Bugzilla: 918907
Upstream status: not applicable
(RHEL-6-only quirk that is not going to be included upstream)
Brew build: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=6290888
The phenom and Opteron_G[123] CPU models don't have RDTSCP enabled on
RHEL-6, so we have to explicitly disable it on pc_init_rhel650() to keep
compatibility.
