55261f4670 perf evlist: Fix creation of cpu map 
Currently, 'perf record -- sleep 1' creates a cpu map for all online
cpus since it turns out calling cpu_map__new(NULL). Fix it.

Also it is guaranteed that cpu_list is NULL if PID/TID is given by
calling perf_target__validate(), so we can make the conditional bit
simpler.

This also fixes perf test 7 (Validate) failure on my 6 core machine:

  $ cat /sys/devices/system/cpu/online
  0-11
  $ ./perf test -v 7
   7: Validate PERF_RECORD_* events & perf_sample fields:
  --- start ---
  perf_evlist__mmap: Operation not permitted
  ---- end ----
  Validate PERF_RECORD_* events & perf_sample fields: FAILED!

9389a46043 perf session: Fail on processing event with unknown size 
Currently if we cannot decide the size of the event, we guess next
event possition by:
  "... check alignment, and increment a single u64 in the hope
  to catch on again 'soon'"

This usually ends up with segfault or endless loop. It's better
to admit the failure right away, then pretend nothing happened.
It makes the life easier ;)

770a34a38b perf tools: Check more combinations of PID/TID, UID and CPU switches 
There were some combinations of these switches that are not so
appropriate IMHO.

Since there are implicit priorities between them and they worked well
anyway, but it ends up opening useless duplicated events.

For example, 'perf stat -t <pid> -a' will open multiple events for the
thread instead of one.

Add explicit checks and warn user in perf_target__validate().

1fa2e84db3 Merge tag 'perf-annotate-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Now the default annotate browser uses a much more compact format, implementing
suggestions made made by several people, notably Linus.

Here is part of the new __list_del_entry() annotation:

    0.00 │      leaveq
    0.00 │      retq

The infrastructure is there to provide formatters for any instruction,
like the one I'll do for call functions to elide the address.

Further fixes on top of the first iteration:

- Sometimes a jump points to an offset with no instructions, make the
  mark jump targets function handle that, for now just ignoring such
  jump targets, more investigation is needed to figure out how to cope
  with that.

- Handle jump targets that are outside the function, for now just don't
  try to draw the connector arrow, right thing seems to be to mark this
  jump with a -> (right arrow) and handle it like a callq.

fb29fa58e3 perf annotate: Mark jump instructions with no offset 
I.e. jumps that go to code outside the current function, that is denoted
in objdump -dS as:

   399f877a9f: jne    399f87bcf4 <_L_lock_5154>

I.e. without the + after the name of the current function, like in:

   399f877aa5: jmp    399f877ab2 <_int_free+0x412>

The browser will use that info to avoid drawing connectors to the start
of the function, since ops.target.addr was zero.

aaf045f723 perf: Have perf use the new libtraceevent.a library 
The event parsing code in perf was originally copied from trace-cmd
but never was kept up-to-date with the changes that was done there.
The trace-cmd libtraceevent.a code is much more mature than what is
currently in perf.

This updates the code to use wrappers to handle the calls to the
new event parsing code. The new code requires a handle to be pass
around, which removes the global event variables and allows
more than one event structure to be read from different files
(and different machines).

But perf still has the old global events and the code throughout
perf does not yet have a nice way to pass around a handle.
A global 'pevent' has been made for perf and the old calls have
been created as wrappers to the new event parsing code that uses
the global pevent.

With this change, perf can later incorporate the pevent handle into
the perf structures and allow more than one file to be read and
compared, that contains different events.

4ace73eef5 perf: Separate out trace-cmd parse-events from perf files 
Move the trace-event-parse.c code that originally came from trace-cmd into
their own files. The new file will be called trace-parse-events.c, as
the name of trace-cmd's file was parse-events.c too, but it conflicted
with the parse-events.c file in perf that parses the command line.

This tries to update the code with mimimal changes.

Perf specific code stays in the trace-event-parse.[ch] files and
the common parsing code is now in trace-parse-events.c and
trace-parse-events.h.

33ff581edd perf symbols: Read plt symbols from proper symtab_type binary 
When loading symbols from DSO we check multiple paths of DSO binary
until we succeed to load symbols ('.symtab' section). Once symbols are
read we try to load also plt symbols.

During the reading of plt symbols, the dso file is reopened from
location given by dso->long_name. This could be wrong in case we want
process buildid binaries.

The change is to make the plt symbols being read from the DSO path, that
normal symbols were read from.

Running 'perf kvm --host --guest --guestmount /tmp/guestmount record -a -g -- sleep 2'

Was resulting in a segfault. For event type PERF_RECORD_MMAP,
event->ip.pid is being used in perf_session__find_machine_for_cpumode,
which is not correct.

The event->ip.pid field happens to be 0 in this case and results in
returning a NULL machine object. Finally, access to self->pid in
machine__mmap_name, results in a segfault later.

For PERF_RECORD_MMAP type, pass event->mmap.pid.

This allows comparing performance of different applications with each

Previously, the sample count was displayed against an 'Events:' heading.
With this patch, the header now reads (for example):

Samples: 5K of event 'instructions'
Event count (approx.): 2993026545

The patch covers both the stdio and the browser interface.

The lines in objdump have this format:

<SNIP>
    ffffffff81265494:       mov    %rdi,%rcx

Since we now have objdump_line allowing tools to print the offset
independently from the rest of the line, allow toggling a view where
just offsets from the start of the function are shown:

     2f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
     84:       mov    %rdi,%rcx

The offset view will be the default as soon as operations that deal with
offsets in a function are handled accodringly, i.e. in offset view the
above will become:

     2f:       jne    __list_del_entry+0x84
<SNIP>
