Subject: [PATCH 0/5] perf events finer grained context instrumentation / context exclusion

Here is the new version of per context exclusion, based on hooks
on irq_enter/irq_exit. I haven't observed slowdowns but I haven't
actually measured the impact.

It's pullable from:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	perf/exclusion-3

It's against latest tip:perf/core.

Thanks.

Frederic Weisbecker (5):
  perf: Provide a proper stop action for software events
  perf: Support disable() after stop() on software events
  perf: New PERF_EVENT_STATE_PAUSED event state
  perf: Introduce task, softirq and hardirq contexts exclusion
  perf: Support for task/softirq/hardirq exclusion on tools
