Bugzilla: 918907
|
|
|
218e99 |
Upstream status: not applicable
|
|
|
218e99 |
(RHEL-6-only quirk that is not going to be included upstream)
|
|
|
218e99 |
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
|
|
|
218e99 |
RHEL-6, so we have to explicitly disable it on pc_init_rhel650() to keep
|
|
|
218e99 |
compatibility.
