Subject[PATCH 24/68] perf c2c report: Add loads related dimension keys
Date
From: Jiri Olsa <jolsa@kernel.org>

Add 3 loads related dimension key wrappers.

They are to be displayed in the main cachelines overall output:

ld_fbhit, ld_l1hit, ld_l2hit

They all display bare numbers of loads for
FB (Fill Buffer), L1 and L2 cache.
