Merge tag 'perf-core-for-mingo-4.12-20170503' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

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

Fixes:

- Support setting probes in versioned user space symbols, such as
pthread_create@@GLIBC_2.1, picking the default one, more work
needed to make it possible to set it on the other versions, as
the 'perf probe' syntax already uses @ for other purposes.
(Paul Clarke)

- Do not special case address zero as an error for routines that
return addresses (symbol lookup), instead use the return as the
success/error indication and pass a pointer to return the address,
fixing 'perf test vmlinux' (the one that compares address between
vmlinux and kallsyms) on s/390, where the '_text' address is equal
to zero (Arnaldo Carvalho de Melo)

Infrastructure changes:

- More header sanitization, moving stuff out of util.h into
more appropriate headers and objects and sometimes creating
new ones (Arnaldo Carvalho de Melo)

- Refactor a duplicated code for obtaining config file name (Taeung Song)

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"The main changes in this cycle were:

Kernel side changes:

- Kprobes and uprobes changes:
- Make their trampolines read-only while they are used
- Make UPROBES_EVENTS default-y which is the distro practice
- Apply misc fixes and robustization to probe point insertion.

- add support for AMD IOMMU events

- extend hw events on Intel Goldmont CPUs

- ... plus misc fixes and updates.

Tooling side changes:

- support s390 jump instructions in perf annotate (Christian
Borntraeger)

- vendor hardware events updates (Andi Kleen)

- add argument support for SDT events in powerpc (Ravi Bangoria)

- beautify the statx syscall arguments in 'perf trace' (Arnaldo
Carvalho de Melo)

- handle inline functions in callchains (Jin Yao)

- enable sorting by srcline as key (Milian Wolff)

- add 'brstackinsn' field in 'perf script' to reuse the x86
instruction decoder used in the Intel PT code to study hot paths to
samples (Andi Kleen)

- add PERF_RECORD_NAMESPACES so that the kernel can record
information required to associate samples to namespaces, helping in
container problem characterization. (Hari Bathini)

- allow sorting by symbol_size in 'perf report' and 'perf top'
(Charles Baylis)

- in perf stat, make system wide (-a) the default option if no target
was specified and one of following conditions is met:
- no workload specified (current behaviour)
- a workload is specified but all requested events are system wide
ones, like uncore ones. (Jiri Olsa)

- ... plus lots of other updates, enhancements, cleanups and fixes"

Merge tag 'perf-core-for-mingo-4.12-20170419' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core cleanups from Arnaldo Carvalho de Melo:

- Introduce new header files out of the hodge-podge that util/util.h
became, trying to disentangle the includes hell that all C projects
end up growing. This should help in build times, as changes to
seemingly unrelated files (util.h included tons of headers) won't
trigger a rebuild of most object files.

- Use equivalent facilities found in the kernel source code base
originated tools/include/ header files, such as __stringify(),
ARRAY_SIZE, that has extra checks (__must_be_array()), etc.

- For that get some more files from the kernel sources, like
include/linux/bug.h, some just with the bits needed at this time.

- Use the headers where facilities declared in them are used, such
as PRIxu(32,64) macros (inttypes.h), errno defines (errno.h), etc.

- Remove various leftovers from the initial code base we copied from
git.git: FLEX_ARRAY, etc.
