Upstream status: not applicable
|
|
|
218e99 |
(RHEL-6-only quirk that is not going to be included upstream)
|

The Opteron_G[123] CPU models had x2apic set since they were first added
|
|
|
218e99 |
to RHEL-6, but they don't have it set upstream. We need to explicitly
|
|
|
218e99 |
set it on pc_init_rhel650() to keep compatibility.
