Subject: [PATCH 04/31] perf c2c record: Record physical addresses in samples
From: Jiri Olsa <jolsa@...nel.org>
We are going to display NUMA node information in following patches. For
this we need to have physical address data in the sample.
Adding --phys-data as a default option for perf c2c record.
