Subject: [PATCH v7 2/8] powerpc/smp: Rename cpu_corgroup_* to cpu_corgrp_*
Rename cpu_corgroup_{map,mask} to cpu_corgrp_{map,mask} to free up the
cpu_corgroup_* namespace. cpu_corgroup_mask() will be added back in the
subsequent commit for CONFIG_SCHED_MC enablement.
No functional changes intended.
