Yes. Will change it to:

PLZA (Privilege Level Zero Association) provides the global per-CPU
kernel mode, RESCTRL_GLOBAL_ENABLE_PER_CPU, allowing kernel work to use
allocation and monitoring associations that differ from user tasks.

Register the PLZA kernel mode with the resctrl kernel mode
infrastructure so it can be exposed through the resctrl filesystem.
