[ Upstream commit 39c0a53b114d0317e5c4e76b631f41d133af5cb0 ]
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.
Committer notes:
This was extracted from a larger patch that also contained kernel
changes.
Fixes: 52839e653b5629bd ("perf tools: Add support for printing new mem_info
encodings")
