Subject: [PATCH 1/5] perf,tools: add processor socket info in hist_entry and addr_location

From: Kan Liang <kan.liang@...el.com>

Add processor socket id info in hist_entry and addr_location.
For perf report, the socket id info is from perf.data.
For others, the socket id info is from current system.
