perf_event.h has macros that define the field offsets in the
data_src bitmask in perf records. The SNOOPX and REMOTE offsets
were both 37. These are distinct fields, and the bitfield layout
in perf_mem_data_src confirms that SNOOPX should be at offset 38.

Looks good.

Probably should have a Fixes: header

Please do so, find the patch that introduced the error, add the Fixes
tag, will help me not having to do it myself :-)

Fixes: 52839e653b562 ("perf tools: Add support for printing new mem_info
encodings")

Ok, I'll add that, thanks.

There was also a minor problem in the patch, there was no separation of
--- from the patch comment section to the patch itself, I'll fix that as
well.

Thanks, will remember for next time.
