Merge branch 'tracing-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'tracing-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (105 commits) ring-buffer: only enable ring_buffer_swap_cpu when needed ring-buffer: check for swapped buffers in start of committing tracing: report error in trace if we fail to swap latency buffer tracing: add trace_array_printk for internal tracers to use tracing: pass around ring buffer instead of tracer tracing: make tracing_reset safe for external use tracing: use timestamp to determine start of latency traces tracing: Remove mentioning of legacy latency_trace file from documentation tracing/filters: Defer pred allocation, fix memory leak tracing: remove users of tracing_reset tracing: disable buffers and synchronize_sched before resetting tracing: disable update max tracer while reading trace tracing: print out start and stop in latency traces ring-buffer: disable all cpu buffers when one finds a problem ring-buffer: do not count discarded events ring-buffer: remove ring_buffer_event_discard ring-buffer: fix ring_buffer_read crossing pages ring-buffer: remove unnecessary cpu_relax ring-buffer: do not swap buffers during a commit ring-buffer: do not reset while in a commit ...
