In case ->data_tail * indicates there is no room in the buffer to store $data we do not. * * D needs to be a full barrier since it separates the data READ * from the tail WRITE. * * For B a WMB is sufficient since it separates two WRITEs, and for C * an RMB is sufficient since it separates two READs. * * See perf_output_begin(). So I'm pretty sure we need a full barrier before writing out data_tail.

Use that instead of a a long, per-architecture, hand curated list of definitions.
