Nested PERF_GLOBAL_CTRL support is not present in the 8.2 kernel. Drop the
|
|
|
22c213 |
features via compat properties, they will be moved to 8.2 machine type compat
|
|
|
22c213 |
properties in the 8.3 timeframe.

No change, for v2 I mistakenly wrote "origin/rhel-av-8.2.0" as the
|
|
|
22c213 |
branch. :(
