Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next

Backmerge to catch up with 4.3. slightly more involved conflict in the
irq code, but nothing beyond adjacent changes.

 --itrace::
 	Options for decoding instruction tracing data. The options are:
 
-		i	synthesize instructions events
-		b	synthesize branches events
-		c	synthesize branches events (calls only)
-		r	synthesize branches events (returns only)
-		x	synthesize transactions events
-		e	synthesize error events
-		d	create a debug log
-		g	synthesize a call chain (use with i or x)
-
-	The default is all events i.e. the same as --itrace=ibxe
-
-	In addition, the period (default 100000) for instructions events
-	can be specified in units of:
-
-		i	instructions
-		t	ticks
-		ms	milliseconds
-		us	microseconds
-		ns	nanoseconds (default)
-
-	Also the call chain size (default 16, max. 1024) for instructions or
-	transactions events can be specified.

 	To disable decoding entirely, use --no-itrace.
 
+--full-source-path::
+	Show the full path for source files for srcline output.

+--show-ref-call-graph::
+	When multiple events are sampled, it may not be needed to collect
+	callgraphs for all of them. The sample sites are usually nearby,
+	and it's enough to collect the callgraphs on a reference event.
+	So user can use "call-graph=no" event modifier to disable callgraph
+	for other events to reduce the overhead.
+	However, perf report cannot show callgraphs for the event which
+	disable the callgraph.
+	This option extends the perf report to show reference callgraphs,
+	which collected by reference event, in no callgraph event.
