Li Zefan d0b6e04a4c tracing/events: Move TRACE_SYSTEM outside of include guard
If TRACE_INCLDUE_FILE is defined, <trace/events/TRACE_INCLUDE_FILE.h>
will be included and compiled, otherwise it will be
<trace/events/TRACE_SYSTEM.h>

So TRACE_SYSTEM should be defined outside of #if proctection,
just like TRACE_INCLUDE_FILE.

Imaging this scenario:

 #include <trace/events/foo.h>
    -> TRACE_SYSTEM == foo
 ...
 #include <trace/events/bar.h>
    -> TRACE_SYSTEM == bar
 ...
 #define CREATE_TRACE_POINTS
 #include <trace/events/foo.h>
    -> TRACE_SYSTEM == bar !!!

and then bar.h will be included and compiled.

Steven Rostedt 1d080d6c31 tracing: remove redundant SOFTIRQ from softirq event traces
After converting the softirq tracer to use te flags options, this
caused a regression with the name. Since the flag was used directly
it was printed out (i.e. HRTIMER_SOFTIRQ).

This patch only shows the softirq name without the SOFTIRQ part.

[ Impact: fix regression of output from softirq events ]

Steven Rostedt c2adae0970 tracing: convert irq events to use __print_symbolic
The recording of the names at trace time is inefficient. This patch
implements the softirq event recording to only record the vector
and then use the __print_symbolic interface to print out the names.

[ Impact: faster recording of softirq events ]

Steven Rostedt 160031b556 tracing/irq: convert irq traces to use TRACE_EVENT macro
The TRACE_FORMAT will soon be deprecated. This patch converts it to
the TRACE_EVENT macro.

Note, this change should also speed up the tracing.

[ Impact: remove a user of deprecated TRACE_FORMAT ]

Steven Rostedt ad8d75fff8 tracing/events: move trace point headers into include/trace/events
Impact: clean up

Create a sub directory in include/trace called events to keep the
trace point headers in their own separate directory. Only headers that
declare trace points should be defined in this directory.
