When you mention linux-next where was it that it picked this from?
For me to get this merged into the perf tools "next" (perf/core) it must
already have been merged in the kernel counterpart (tip/perf/core).
Ok so it is not in tip/perf/core, but got in next yesterday, and PeterZ
acked it, good, will process it soon.

perf: Add perf_event_attr::config3
Arm SPEv1.2 adds another 64-bits of event filtering control. As the
existing perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config3' field.
