Power7 supports over 530 different perf events but only a small subset
of these can be specified by name, for the remaining events, we must
specify them by their raw code:

        perf stat -e r2003c <application>

This patch makes all the POWER7 events available in sysfs.  So we can
instead specify these as:

        perf stat -e 'cpu/PM_CMPLU_STALL_DFU/' <application>

where PM_CMPLU_STALL_DFU is the r2003c in previous example.

Before this patch is applied, the size of power7-pmu.o is:

$ size arch/powerpc/perf/power7-pmu.o
   text	   data	    bss	    dec	    hex	filename
   3073	   2720	      0	   5793	   16a1	arch/powerpc/perf/power7-pmu.o

and after the patch is applied, it is:

$ size arch/powerpc/perf/power7-pmu.o
   text	   data	    bss	    dec	    hex	filename
  15950	  31112	      0	  47062	   b7d6	arch/powerpc/perf/power7-pmu.o

For the run time overhead, I use two scripts, one is "event_name.sh",
which contains 50 event names, it looks like:

 # ./perf record  -e 'cpu/PM_CMPLU_STALL_DFU/' -e .....  /bin/sleep 1

the other one is named "event_code.sh" which use corresponding  events
raw
code instead of events names, it looks like:

 # ./perf record -e r2003c -e ......  /bin/sleep 1

below is the result.

Using events name:

[root@localhost perf]# time ./event_name.sh
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.002 MB perf.data (~102 samples) ]

real	0m1.192s
user	0m0.028s
sys	0m0.106s

Using events raw code:

[root@localhost perf]# time ./event_code.sh
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.003 MB perf.data (~112 samples) ]

There's no point of having out_delete label with perf_session__delete
call within __cmd_report function, because it's called at the end of the
cmd_report function.

The speed up due to commenting out the perf_session__delete at the end
does not seem relevant anymore. Measured speedup for ~1GB data file with
222466 FORKS events is around 0.5%.

Most tracepoint events already have their system and event name in
->name field so that searching whole event tracing directory for each
evsel to match given id is suboptimal.

Factor out this routine into tracepoint_name_to_path().  In case of en
invalid name, it'll try to find path using id again.

perf: Add objdump option to 'perf top'

Like with 'perf annotate' add the --objdump option to perf top so users
can specify an alternate path to the /usr/bin/objdump binary.

The CPU map is in an "empty" (or not-applicable) state when monitoring
specific threads.

cpu_map__all() returns true if the CPU map is in this empty state (i.e
for the 'empty_cpu_map' or if we created the map via
cpu_map__dummy_new().

The name, cpu_map__all(), is misleading, because even when monitoring
all CPUs, (eg: perf record -a), cpu_map__all() returns false.

Rename cpu_map__all() to cpu_map__empty().

It gives the following benefits:

  - only one function pointer is passed along the way

  - the 'match' function is called within output function
    and could be inlined by the compiler
