In commit a21b0b354d4a ('perf: Introduce a flag to enable
close-on-exec in perf_event_open()'), flag PERF_FLAG_FD_CLOEXEC
was added to perf_event_open(2) syscall to allows userspace
to atomically enable close-on-exec behavor when creating
the file descriptor.
This patch makes perf tools use the new flag if supported
by the kernel, so that the event file descriptors got
automatically closed if perf tool exec a sub-command.

It is possible to record a perf.data file on one architecture and
process it on another.
Consequently, TSC conversion functions need to be moved out of the arch
directory.

Parts of a 'perf kvm stat' code make sense only for x86.
Let's move this code into the arch/x86/kvm-stat.c file and add
util/kvm-stat.h for generic structure definitions.
Add a global array 'kvm_reg_events_ops' for accessing the arch-specific
'kvm_events_ops' from generic code.
Since the several global arrays (i.e. 'kvm_events_tp') have been moved
to arch/*, we can not know their sizes and use them directly in
builtin-kvm.c. This patch fixes that problem by adding trimming NULL
element to each array and changing the behavior of their handlers in
generic code.

Currently 'make help' message has such hint:
use "make prefix=<path> <install target>" to install to a particular
path like make prefix=/usr/local install install-doc
But this is misleading, when I specify "prefix=/usr/local", it has got no
respect at all.
This is because that, "DESTDIR" is considered first. In this case, "DESTDIR"
has an empty value, so "prefix" is honored. However, "prefix" is unconditionally
assigned to $HOME, regardless of what it is set to from command line. So our
"prefix" setting got no respect and the actual destination falls back to $HOME.
This patch fixes this issue and corrects the help message.

This program is particularly useful to measure the latency of nthread
requeues without waking up any tasks -- thus mimicking a regular
futex_wait.

Introduce futexes to perf-bench and add a program that stresses and
measures the kernel's implementation of the hash table.
This is a multi-threaded program that simply measures the amount of
failed futex wait calls - we only want to deal with the hashing
overhead, so a negative return of futex_wait_setup() is enough to do the
trick.
An example run:
$ perf bench futex hash -t 32
Run summary [PID 10989]: 32 threads, each operating on 1024 [private] futexes for 10 secs.
[thread 0] futexes: 0x19d9b10 ... 0x19dab0c [ 418713 ops/sec ]
[thread 1] futexes: 0x19daca0 ... 0x19dbc9c [ 469913 ops/sec ]

...
[thread 31] futexes: 0x19fbb80 ... 0x19fcb7c [ 464179 ops/sec ]

Factor NO_LIBDW_DWARF_UNWIND makefile variable and code that selects
default DWARf post unwinder based on detected features (libdw and
libunwind support)
If both are detected the libunwind is selected as default. Simple
'make' will try to add:
- libunwind unwinder if present
- libdw unwinder if present
- disable dwarf unwind if non of libunwind and libdw
libraries are present
If one of the DWARF unwind libraries is detected, message is displayed
which one (libunwind/libdw) is compiled in.
Examples:
- compile in libdw unwinder if present:
$ make NO_LIBUNWIND=1
- compile in libdw (with libdw installation directory) unwinder if present:
$ make LIBDW_DIR=/opt/elfutils/ NO_LIBUNWIND=1

Adding libdw DWARF post unwind support, which is part of
elfutils-devel/libdw-dev package from version 0.158.
The new code is contained in unwin-libdw.c object, and implements
unwind__get_entries unwind interface function.
New Makefile variable NO_LIBDW_DWARF_UNWIND was added to control its
compilation, and is marked as disabled now. It's factored with the rest
of the Makefile unwind build code in the next patch.
Arch specific code was added for x86.

Currently the we display all detected features/libraries by following
rules:
- if one of the features is missing
- if it's build from clean tree
This patch changes changes this behavior in several ways.
- We no longer display all detected features, only detected libraries
are displayed by default:
$ make
BUILD: Doing 'make -j4' parallel build
Auto-detecting system features:
... dwarf: [ on ]
... glibc: [ on ]
... gtk2: [ on ]
... libaudit: [ on ]
... libbfd: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
... libperl: [ on ]
... libpython: [ on ]
... libslang: [ on ]
... libunwind: [ on ]
The assumption is, that above libraries are the most interesting part
of the detection, while we don't care much about detection of on-exit
support.
- If all above libraries are detected, the default is not shown on
subsequent builds.
- If one of the above libraries is missing, the detection output is
forced.
- The features status is stored in PERF-FEATURES file and the detection
output is forced in case the there's difference between the file
contents and currently detected features.
- If you want to see all detected features, you can use VF=1 make
variable, that forces the detected features output.

This could lead to build failure if the one of those objects is picked
up by make to be build as the first one (reported by Arnaldo).
Also following make fails:

This was needed at the time before e66eed651fd1 ("list: remove
prefetching from regular list iterators") where the list iterators did
prefetch elements. This turned out to be counter-productive and hurt
performance and they were removed. Which makes the prefetch.h header
unused so drop it.

Making perf_reg_value function global (formely reg_value), because it's
going to be used globaly across all code providing the dwarf post unwind
feature.
Changing its prototype to be generic:
-int reg_value(unw_word_t *valp, struct regs_dump *regs, int id)
+int perf_reg_value(u64 *valp, struct regs_dump *regs, int id);
Changing the valp type from libunwind specific 'unw_word_t' to u64.

Adding dwarf unwind test, that setups live machine data over the perf
test thread and does the remote unwind.
At this moment this test fails due to bug in the max_stack processing in
unwind__get_entries function. This is fixed in following patch.
Need to use -fno-optimize-sibling-calls for test compilation, otherwise
'krava_*' function calls are optimized into jumps and ommited from the
stack unwind.
So far it's enabled only for x86.

Currently the feature-checks Makefile does not inherit $(CC), and calls
cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the
native toolchain rather than the cross toolchain, and can identify
features as available when they are not. This can break the build.
Additionally the native pkg-config is always called as opposed to
$(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed
to the cross compiler.
This patch passes CROSS_COMPILE down to the feature-checks Makefile, and
forces its use. Additionally pkg-config is replaced with
$(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable. This patch
has been build tested on x86_64 and arm.

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.
For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.
acme:
"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.
But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Eventually this should be useful to other tools/ living utilities.
For now don't try to build any .a, just trying the minimal approach of
separating existing code into multiple .c files that can then be
included wherever they are needed, using whatever build machinery
already in place.

This new COMM infrastructure provides two features:
1) It keeps track of all comms lifecycle for a given thread. This way we
can associate a timeframe to any thread COMM, as long as
PERF_SAMPLE_TIME samples are joined to COMM and fork events.
As a result we should have more precise COMM sorted hists with seperated
entries for pre and post exec time after a fork.
2) It also makes sure that a given COMM string is not duplicated but
rather shared among the threads that refer to it. This way the threads
COMM can be compared against pointer values from the sort
infrastructure.

The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:
CC builtin-buildid-list.o

CC builtin-list.o
CC FPIC trace-seq.o
CC builtin-record.o
CC FPIC parse-filter.o
CC builtin-report.o

CC builtin-timechart.o
CC builtin-top.o
CC builtin-script.o
BUILD STATIC LIB libtraceevent.a
CC builtin-probe.o
CC builtin-kmem.o
CC builtin-lock.o
To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.
After the patch the output looks pretty tidy, even if output lines get
mixed up:
CC builtin-annotate.o
