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

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

 * Don't show scripts menu for 'perf top', fix from Feng Tang

 * Add framework for automated perf_event_attr tests, where tools with
   different command line options will be run from a 'perf test', via
   python glue, and the perf syscall will be intercepted to verify that
   the perf_event_attr fields set by the tool are those expected,
   from Jiri Olsa

 * Use normalized arch name for searching objdump path. This fixes cases
   where the system's objdump (e.g. x86_64) supports the architecture in
   the perf.data file (e.g. i686), but is not the same,
   fix from Namhyung Kim.

 * Postpone objdump check until annotation requested, from Namhyung Kim.

 * Add a 'link' method for hists, so that we can have the leader with
   buckets for all the entries in all the hists.  This new method
   is now used in the default 'diff' output, making the sum of the 'baseline'
   column be 100%, eliminating blind spots. Now we need to use this
   for 'diff' with > 2 perf.data files and for multi event 'report' and
   'annotate'.

 * libtraceevent fixes for compiler warnings trying to make perf it build
   on some distros, like fedora 14, 32-bit, some of the warnings really
   pointed to real bugs.

 * Remove temp dir on failure in 'perf test', fix from Jiri Olsa.

 * Fixes for handling data, stack mmaps, from Namhyung Kim.

 * Fix live annotation bug related to recent objdump lookup patches, from
   Namhyung Kim

 * Don't try to follow jump target on PLT symbols in the annotation browser,
   fix from Namhyung Kim.

 * Fix leak on hist_entry delete, from Namhyung Kim.

 * Fix a CPU_ALLOC related build error on builtin-test, from Zheng Liu.

The struct perf_event_attr test (attr tests) support
====================================================
This testing support is embedded into perf directly and is governed
by the PERF_TEST_ATTR environment variable and hook inside the
sys_perf_event_open function.
The general idea is to store 'struct perf_event_attr' details for
each event created within single perf command. Each event details
are stored into separate text file. Once perf command is finished
these files are checked for values we expect for command.
The attr tests consist of following parts:
tests/attr.c
------------
This is the sys_perf_event_open hook implementation. The hook
is triggered when the PERF_TEST_ATTR environment variable is
defined. It must contain name of existing directory with access
and write permissions.
For each sys_perf_event_open call event details are stored in
separate file. Besides 'struct perf_event_attr' values we also
store 'fd' and 'group_fd' values to allow checking for groups.
tests/attr.py
-------------
This is the python script that does all the hard work. It reads
the test definition, executes it and checks results.
tests/attr/
-----------
Directory containing all attr test definitions.
Following tests are defined (with perf commands):
perf record kill (test-record-basic)
perf record -b kill (test-record-branch-any)
perf record -j any kill (test-record-branch-filter-any)
perf record -j any_call kill (test-record-branch-filter-any_call)
perf record -j any_ret kill (test-record-branch-filter-any_ret)
perf record -j hv kill (test-record-branch-filter-hv)
perf record -j ind_call kill (test-record-branch-filter-ind_call)
perf record -j k kill (test-record-branch-filter-k)
perf record -j u kill (test-record-branch-filter-u)
perf record -c 123 kill (test-record-count)
perf record -d kill (test-record-data)
perf record -F 100 kill (test-record-freq)
perf record -g -- kill (test-record-graph-default)
perf record -g dwarf -- kill (test-record-graph-dwarf)
perf record -g fp kill (test-record-graph-fp)
perf record --group -e cycles,instructions kill (test-record-group)
perf record -e '{cycles,instructions}' kill (test-record-group1)
perf record -D kill (test-record-no-delay)
perf record -i kill (test-record-no-inherit)
perf record -n kill (test-record-no-samples)
perf record -c 100 -P kill (test-record-period)
perf record -R kill (test-record-raw)
perf stat -e cycles kill (test-stat-basic)
perf stat kill (test-stat-default)
perf stat -d kill (test-stat-detailed-1)
perf stat -dd kill (test-stat-detailed-2)
perf stat -ddd kill (test-stat-detailed-3)
perf stat --group -e cycles,instructions kill (test-stat-group)
perf stat -e '{cycles,instructions}' kill (test-stat-group1)
