Reducing the exposure of perf_session further, so that we can use the
classes in cases where no perf.data file is created.

So that we don't need to have that many globals.
Next steps will remove the 'session' pointer, that in most cases is
not needed.
Then we can rename perf_event_ops to 'perf_tool' that better describes
this class hierarchy.

Paving the way to remove these globals when we change the perf_event_ops
to receive as a first parameter a pointer to a perf_event_ops that will
then provide access to perf_annotate via container_of.

The 'machine' abstraction was introduced with 'perf kvm' where we could
have samples for the host and multiple guests, but at the time we ended
up keeping the list of all machines threads all in
session->host_machine.
Move the threads rb_tree to struct machine to separate the namespaces.

We don't need to have two PATH_MAX char sized arrays holding it, just
one in util/debugfs.c will do.
Also rename debugfs_path to tracing_events_path, as it is not the path
to debugfs, that is debugfs_mountpoint. Both are now accessible.
This will allow accessing this code in the perf python binding without
having to drag in perf.c and util/parse-events.c.
The defaults for these variables are the canonical "/sys/kernel/debug"
and "/sys/kernel/debug/tracing/events/", removing the need for simple
tools to call debugfs_mount(NULL).

A update is made to the sched:sched_switch event that adds some
logic to the first parameter of the __print_flags() that shows the
state of tasks. This change cause perf to fail parsing the flags.
A simple fix is needed to have the parser be able to process ops
within the argument.

In the old --stdio interface the annotation is done just after one
selects a symbol, while in --tui, now the default when the required libs
are installed, we annotate all symbols with samples so that when
annotation is asked we see what happened recently on that symbol.
To achieve that the --stdio variant checks if the hist_entry being
processed is the one selected by the user via the 's' hotkey. What
happens now that we share the hist_entry abstractions with 'perf report'
is that for minimizing locking contention multiple rb_trees are used,
one for collecting the samples and other to browse/show them after
resorting it by number of samples and decay them, which is done
periodically.
So the simple test in record_precise_ip doesn't work as we move
hist_entries between those rb_trees. To fix it just check that the
underlying struct symbol associated with those hist_entries is the same.

Just like the old perf top --tui and the --stdio version.
But because we have the initial menu to choose which event to show in a

each of the event types, clarifying which events are being affected the

We were doing parts of it in hists__collapse_resort and parts of it in
hists__output_resort, leading to a bogus total_period.
Fix it by doing just the filtering operation when collapsing because
there we know that the Zoom operations adds filters just what is in
hists->entries, not to the new batch of entries being collapsed.
And move all the nr_entries + total_period recalculation to
hists__output_resort since we will traverse all entries anyway there.
Problem introduced when developing threaded addition of new batches
of hist_entries, i.e. post v3.1.

No need to unblock it at each ui__getch() and also allow other users to

The 'force' one shouldn't be needed, but its in a slow path, so leave it

Fix up conflicts in arch/x86/kernel/kprobes.c manually.
Ingo's tree did the insane "add volatile to const array", which just
doesn't make sense ("volatile const"?). But we could remove the const
*and* make the array volatile to make doubly sure that gcc doesn't
optimize it away..
Also fix up kernel/trace/ring_buffer.c non-data-conflicts manually: the
reader_lock has been turned into a raw lock by the core locking merge,
and there was a new user of it introduced in this perf core merge. Make
sure that new use also uses the raw accessor functions.

The __perf_evsel__open routing was grouping just the threads for that
specific events per cpu when we want to group all threads in all events
to the first fd opened on that cpu.
So pass the xyarray with the first event, where the other events will be
able to get that first per cpu fd.
At some point top and record will switch to using perf_evlist__open that
takes care of this detail and probably will also handle the fallback
from hw to soft counters, etc.

Fglrx propietary driver has symbol names over 128 chars (:S). This
breaks the function kallsyms__parse.
This fix increases the size of KSYM_NAME_LEN, so kallsyms__parse can
work on such kernels.
The only counterparty, is that such function requires 128 more bytes to
work.

We don't allocate the histogram data structures for --sort lists without
"sym", so, just like was done for the menu, don't try to annotate when
'a' is pressed, just warn the user about it.

Fixing the way the tracing information is stored within record command.
The current implementation is causing issues for pipe output.
Following commands fail currently:
perf script syscall-counts ls
perf record -e syscalls:sys_exit_read ls | ./perf report -i -
The tracing information is part of the perf data file. It contains
several files from within the tracing debugfs and procs directories.
Beside some static header files, for each tracing event the format
file is added. The /proc/kallsyms file is also added.
The tracing data are stored with preceeding size. This is causing some
dificulties for pipe output, since there's no way to tell debugfs/proc
file size before reading it. So, for pipe output, all the debugfs files
were read twice. Once to get the overall size and once to store the
content itself. This can cause problem in case any of these file
changed, within the storage time.
To fix this behaviour and ensure the integrity of the tracing data, we:
- read debugfs/proc file into the temp file
- get temp file size and dump it to the pipe
- dump the temp file contents to the pipe

And also no leed to show the [.] (level: k, . for userspace) when
showing just one DSO.

Following the 'perf report' model we don't zap hist_entry instances from
the rb tree, we just keep them with he->filtered set to a mask of the
filters applied to it (thread, parent, DSO so far).
In top we need to decay even filtered entries, but we better not touch
total_period for them...
Now everything seems to work when filters are applied on top as they
worked in 'report', i.e. both dynamic and static hist entry browsing
works with filters.

We lost that when we move it outside hist_entry__snprintf, but better
leave it untangled of 'perf diff' stuff (pair_hist, etc).
