JIRA: https://issues.redhat.com/browse/RHEL-32987

rh_flags is a mechanism that allows tracking usage of specific kernel features. The list of used features is accessible via procfs and is printed in panic messages. It's meant to provide better customer support making possible for support engineers to be able to see what specific features were used and steer the support accordingly.

Ricardo Robaina (6): add support for rh_features add rh_features to /proc rh_features: convert to atomic allocation rh_features: move rh_features entry to sys/kernel kernel: rh_features: fix reading empty feature list from /proc rh_flags: Rename rh_features to rh_flags
