This patch is to enable sample type PERF_SAMPLE_DATA_SRC for Arm SPE in
the perf data, when output the tracing data, it tells tools that it
contains data source in the memory event.

Signed-off-by: Leo Yan <redacted>
Signed-off-by: James Clark <redacted>
I see two Signed-off-by, ok, any Reviewed-by?

Hi Arnaldo,

I have submitted v2 and added my reviewed-by and tested-by.

I didn't change any of the authors as Leo suggested because I only
modified the last two patches which we dropped anyway to not show
any misleading PID data when run from a container.


Thanks
James
