Subject: [PATCH] arch/x86: Remove vendor specific CPU ID checks
|
||
|
|
|
||
|
|
Upstream Status: RHEL only
|
||
|
|
|
||
|
|
After discussions with Devel, QE, Support, and Certification we have
|
||
|
|
decided to drop the CPU specific checks in rh_check_supported().
|
||
|
|
Certification is adopting a new process in which CPU certifications will
|
||
|
|
be tracked on https://catalog.redhat.com.
|
||
|
|
|
||
|
|
Remove the vendor specific CPU ID checks from rh_check_supported().
|
||
|
