Merge tag 'trace-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing update from Steven Rostedt: "Mostly this is just clean ups and micro optimizations. The changes with more meat are: - Allowing the trace event filters to filter on CPU number and process ids - Two new markers for trace output latency were added (10 and 100 msec latencies) - Have tracing_thresh filter function profiling time I also worked on modifying the ring buffer code for some future work, and moved the adding of the timestamp around. One of my changes caused a regression, and since other changes were built on top of it and already tested, I had to operate a revert of that change. Instead of rebasing, this change set has the code that caused a regression as well as the code to revert that change without touching the other changes that were made on top of it" * tag 'trace-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Revert "ring-buffer: Get timestamp after event is allocated" tracing: Don't make assumptions about length of string on task rename tracing: Allow triggers to filter for CPU ids and process names ftrace: Format MCOUNT_ADDR address as type unsigned long tracing: Introduce two additional marks for delay ftrace: Fix function_graph duration spacing with 7-digits ftrace: add tracing_thresh to function profile tracing: Clean up stack tracing and fix fentry updates ring-buffer: Reorganize function locations ring-buffer: Make sure event has enough room for extend and padding ring-buffer: Get timestamp after event is allocated ring-buffer: Move the adding of the extended timestamp out of line ring-buffer: Add event descriptor to simplify passing data ftrace: correct the counter increment for trace_buffer data tracing: Fix for non-continuous cpu ids tracing: Prefer kcalloc over kzalloc with multiply
