[V3 06/10] powerpc, perf: Change the name of HW PMU branch filter tracking variable

From: Anshuman Khandual
Date: Wed Oct 16 2013 - 03:01:25 EST


This patch simply changes the name of the variable from "bhrb_filter" to
"bhrb_hw_filter" in order to add one more variable which will track SW
filters in generic powerpc book3s code which will be implemented in the
subsequent patch.
