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.
