Subject: [PATCH 2/2] perf, x86: Use INTEL_FLAGS_UEVENT_CONSTRAINT for PRECDIST
From: Andi Kleen <ak@...ux.intel.com>
The earlier commit 86a04461a made near all PEBS on
Sandy/IvyBridge/Haswell to reject non zero flags.
However this wasn't done for the INST_RETIRED.PREC_DIST event
because no suitable macro existed. Now that we have
INTEL_FLAGS_UEVENT_CONSTRAINT enforce zero flags for
INST_RETIRED.PREC_DIST too.
