Pulled into tip/tracing/ftrace, thanks Steve!

There was a conflict in kernel/trace/trace_hw_branches.c - i resolved it,
please double-check the end result.

One small detail, for future pull requests to me, could you please use the
customary "tracing: " tags for generic commits, instead the "trace: " tag
you started using recently? Thanks,

	Ingo
