Ok, I fixed this and did the rename to cpu_cache_level, tested and
merged it, going to the next patchkit.
Thanks! Useful feature, we should use it in other places, like: record
same workload in different machines, say Ivy Bridge and Broadwell, do
'perf diff' and see the CPU cache topology difference in addition to
other symbolic, per DSO, etc diffs.
