I.e. don't drop al->filtered entries, create the hist_entries and use
its ->filtered bitmap, that is kept with the same semantics for its
bitmap, leaving the filtering to be done at the hist_entry level, i.e.
in the UIs.
This will allow zooming in/out the filters.

The TUI of perf report and top support annotation, but stdio and GTK
don't. So it should be checked before calling hist_entry__inc_addr_
samples() to avoid wasting resources that will never be used.
perf annotate need it regardless of UI and sort keys, so the check
of whether to allocate resources should be on the tools that have
annotate as an option in the TUI, 'report' and 'top', not on the
function called by all of them.
It caused perf annotate on ppc64 to produce zero output, since the
buckets were not being allocated.

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.
Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

When callgraph data was included in the perf data file, it may take a
long time to scan all those data and merge them together especially if
the stored callchains are long and the perf data file itself is large,
like a Gbyte or so.
The callchain stack is currently limited to PERF_MAX_STACK_DEPTH (127).
This is a large value. Usually the callgraph data that developers are
most interested in are the first few levels, the rests are usually not
looked at.
This patch adds a new --max-stack option to perf-report to limit the
depth of callchain stack data to look at to reduce the time it takes for
perf-report to finish its processing. It trades the presence of trailing
stack information with faster speed.
The following table shows the elapsed time of doing perf-report on a
perf.data file of size 985,531,828 bytes.

Extend the perf branch sorting code to support sorting by in_tx
or abort_tx qualifiers. Also print out those qualifiers.
This also fixes up some of the existing sort key documentation.
We do not support no_tx here, because it's simply not showing
the in_tx flag.

This patch adds support for the new PERF_RECORD_MMAP2 record type
exposed by the kernel. This is an extended PERF_RECORD_MMAP record.
It adds for each file-backed mapping the device major, minor number and
the inode number and generation.
This triplet uniquely identifies the source of a file-backed mapping. It
can be used to detect identical virtual mappings between processes, for
instance.
The patch will prefer MMAP2 over MMAP.

With programs with very large functions it can be useful to distinguish
the callgraph nodes on more than just function names. So for example if
you have multiple calls to the same function, it ends up being separate
nodes in the chain.
This patch adds a new key field to the callgraph options, that allows
comparing nodes on functions (as today, default) and addresses.
Longer term it would be nice to also handle src lines, but that would
need more changes and address is a reasonable proxy for it today.
I right now reference the global params, as there was no simple way to
register a params pointer.

Removing event types framework completely. The only remainder (apart
from few comments) is following enum:
enum perf_user_event_type {

PERF_RECORD_HEADER_EVENT_TYPE = 65, /* deprecated */

}
It's kept as deprecated, resulting in error when processed in
perf_session__process_user_event function.

For example, in an application with an expensive function implemented
with deeply nested recursive calls, the default call-graph presentation
is dominated by the different callchains within that function. By
ignoring these callees, we can collect the callchains leading into the
function and compactly identify what to blame for expensive calls.
For example, in this report the callers of garbage_collect() are
scattered across the tree:
$ perf report -d ruby 2>- | grep -m10 ^[^#]*[a-z]
22.03% ruby [.] gc_mark
--- gc_mark
|--59.40%-- mark_keyvalue
| st_foreach
| gc_mark_children
| |--99.75%-- rb_gc_mark
| | rb_vm_mark
| | gc_mark_children
| | gc_marks
| | |--99.00%-- garbage_collect
If we ignore the callees of garbage_collect(), its callers are coalesced:
$ perf report --ignore-callees garbage_collect -d ruby 2>- | grep -m10 ^[^#]*[a-z]
72.92% ruby [.] garbage_collect
--- garbage_collect
vm_xmalloc
|--47.08%-- ruby_xmalloc
| st_insert2
| rb_hash_aset
| |--98.45%-- features_index_add
| | rb_provide_feature
| | rb_require_safe
| | vm_call_method

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%.

Currently we have symbol_conf.exclude_other being set as true every time
so the -x/--exclude-other has nothing to do.
Also we have no way to see the data with symbol_conf.exclude_other being
false which is useful sometimes.
Fixing it by making symbol_conf.exclude_other false by default.
1) Example without -x option:
$ perf report -i perf.data.delete -p perf_session__delete -s parent
+ 99.91% [other]
+ 0.08% perf_session__delete
+ 0.00% perf_session__delete_dead_threads
+ 0.00% perf_session__delete_threads
2) Example with -x option:
$ ./perf report -i perf.data.delete -p perf_session__delete -s parent -x
+ 96.22% perf_session__delete
+ 1.89% perf_session__delete_dead_threads
+ 1.89% perf_session__delete_threads
In Example 1) we get the sorted out data together with the rest
"[other]". This could help us estimate how much time we spent in the
sorted data.
In Example 2) the total is just the sorted data.
