Subject: [PATCH] cpu_map: Remove monitor feature from EPYC-Rome

The feature is filtered by KVM and never automatically enabled. So even
|
|
|
7548c0 |
though QEMU definition of EPYC-Rome contains this feature, the guest
|
|
|
7548c0 |
won't see it. Also domain capabilities will show it as disabled for KVM
|
|
|
7548c0 |
domains. Thus the feature should not really be included in our
|
|
|
7548c0 |
definition of EPYC-Rome.
