Subject: [PATCH 2/5] perf tools: add sort option phys_daddr
From: Kan Liang <kan.liang@...el.com>
Add a new sort option phys_daddr for --mem-mode sort. With this option
applied, perf can sort and report by sample's physical address.
Signed-off-by: Kan Liang <kan.liang@...el.com>

- dcacheline: the cacheline the data address is on at the time of the sample

And the default sort keys are changed to local_weight, mem, sym, dso,
