perf uses sscanf extension %as to read and allocate a string in the same
step.  This is a non-standard extension only present in new versions of
glibc.

Replacing the use of sscanf and %as with strtok_r calls in order to
parse a given string into its components.  This is needed in Android
since bionic does not support
%as extension for sscanf.

Following the model of 'perf sched':

. raw_field_value searches first on the common fields, that are unused
  in this tool

. Leave using perf_evsel__intval to the actual handlers, some may not
  need to incur some of the cost because they may not need all the
  fields values.

. Using perf_session__set_tracepoints_handlers will save all those
  strcmp to find the right handler at sample processing time, do it just
  once and get the handler from evsel->handler.func.

Using plain raw_field_value(evsel->tp_format) will look at the common
fields as well, and since this tool doesn't need those, speed it up a
bit by looking at just the event specific fields.

Also in general use just evsel and sample, just like was done in 'perf
sched'.

Add 'perf kvm stat' support to analyze kvm vmexit/mmio/ioport smartly

Usage:
- kvm stat
  run a command and gather performance counter statistics, it is the alias of
  perf stat

- trace kvm events:
  perf kvm stat record, or, if other tracepoints are interesting as well, we
  can append the events like this:
  perf kvm stat record -e timer:* -a

  If many guests are running, we can track the specified guest by using -p or
  --pid, -a is used to track events generated by all guests.

- show the result:
  perf kvm stat report

The output example is following:
13005
13059

total 2 guests are running on the host

Then, track the guest whose pid is 13059:
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.253 MB perf.data.guest (~11065 samples) ]

Parallel builds of perf were failing for me on a 32p box, with:

    * new build flags or prefix
util/pmu.l:7:23: error: pmu-bison.h: No such file or directory

...

make: *** [util/pmu-flex.o] Error 1
make: *** Waiting for unfinished jobs....

This can pretty quickly be seen by adding a sleep in front of the bison
calls in tools/perf/Makefile and running make -j4 on a smaller box i.e.:

	sleep 10; $(QUIET_BISON)$(BISON) -v util/pmu.y -d -o $(OUTPUT)util/pmu-bison.c

Adding the following dependencies fixes it for me.

Fix it by using the "%PRIu64" for __u64.

If user doesn't explicitly specify CPU list, perf-stat only collects
events on CPUs listed in the PMU cpumask file.

This patch adds a cpumask file to the uncore pmu sysfs directory.  The
cpumask file contains one active cpu for every socket.

The perf_hpp__init() function was only called from setup_browser() so
that the pipe-mode missed the initialization thus didn't respond to
related options.  Fix it.

Report/top commands support to only handle specific symbols with
"--symbols" option, but current code will keep those samples whose
symbol can't be resolved, which should actually be filtered.

If we run following commands:
$perf record -a tree
$perf report --symbols intel_idle -n
the output will be:

On some systems, tar needs to specify the name of the archive immediately
after the -f parameter.

Change the order of the parameters so tar can run properly.

The integrated annotation feature is supported only in TUI mode.  Also
it should be enabled with 'symbol' sort key otherwise resulting hist
entry doesn't need to have same symbol as of a sample so that it can
fail on hist_entry__inc_addr_samples with -ERANGE.

You can easily see it when start perf report TUI without symbol* sort
key.  This patch fixes the problem.
