Peter Zijlstra 030a976efa perf: Consider OS filter fail ... Some PMUs (notably the traditional hardware kind) have boundary issues with the OS filter. Specifically, it is possible for perf_event_attr::exclude_kernel=1 events to trigger in-kernel due to SKID or errata. This can upset the sigtrap logic some and trigger the WARN. However, if this invalid sample is the first we must not loose the SIGTRAP, OTOH if it is the second, it must not override the pending_addr with a (possibly) invalid one.
