Merge commit 'tracing/core' into tracing/kprobes
Conflicts: kernel/trace/trace_export.c kernel/trace/trace_kprobe.c Merge reason: This topic branch lacks an important build fix in tracing/core: 0dd7b74787eaf7858c6c573353a83c3e2766e674: tracing: Fix double CPP substitution in TRACE_EVENT_FN that prevents from multiple tracepoint headers inclusion crashes.
