Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Improved kbprobes robustness

- Intel PEBS support for PT hardware tracing

- Other Intel PT improvements: high order pages memory footprint
reduction and various related cleanups

- Misc cleanups

The perf tooling side has been very busy in this cycle, with over 300
commits. This is an incomplete high-level summary of the many
improvements done by over 30 developers:

- Lots of updates to the following tools:

'perf c2c'
'perf config'
'perf record'
'perf report'
'perf script'
'perf test'
'perf top'
'perf trace'

- Updates to libperf and libtraceevent, and a consolidation of the
proliferation of x86 instruction decoder libraries.

- Vendor event updates for Intel and PowerPC CPUs,

- Updates to hardware tracing tooling for ARM and Intel CPUs,

- ... and lots of other changes and cleanups - see the shortlog and
Git log for details"

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

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Clean up the x86 instruction decoder (Masami Hiramatsu)

- Add new uprobes optimization for PUSH instructions on x86 (Yonghong
Song)

- Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)

- Fix misc bugs, update documentation, plus various cleanups (Jiri
Olsa)

There's a large number of tooling side improvements:

- Intel-PT/BTS improvements (Adrian Hunter)

- Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)

- Introduce an errno code to string facility (Hendrik Brueckner)

- Various build system improvements (Jiri Olsa)

- Add support for CoreSight trace decoding by making the perf tools
use the external openCSD (Mathieu Poirier, Tor Jeremiassen)

- Add ARM Statistical Profiling Extensions (SPE) support (Kim
Phillips)

- libtraceevent updates (Steven Rostedt)

- Intel vendor event JSON updates (Andi Kleen)

- Introduce 'perf report --mmaps' and 'perf report --tasks' to show
info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)

- Add infrastructure to record first and last sample time to the
perf.data file header, so that when processing all samples in a
'perf record' session, such as when doing build-id processing, or
when specifically requesting that that info be recorded, use that
in 'perf report --time', that also got support for percent slices
in addition to absolute ones.

I.e. now it is possible to ask for the samples in the 10%-20% time
slice of a perf.data file (Jin Yao)

- Allow system wide 'perf stat --per-thread', sorting the result (Jin
Yao)

[root@jouet ~]# perf stat --per-thread --metrics IPC

- Improve shell auto-completion of perf events (Jin Yao)

- Fix symbol fixup issues in arm64 due to ELF type (Kim Phillips)

- Ignore threads when they vanish after procfs based enumeration and
before we try to use them with sys_perf_event_open(), i.e. just remove
them from the thread_map and continue with the rest. This makes, among
other cases, the previous new feature (perf stat --per-thread for system
wide, albeit that not seeming to be the motivation for this patch) more
robust. (Mengting Zhang)

- Generate s390 syscall table from asm/unistd.h, doing like x86,
removing the dependency on audit-libs to do this id->string translation,
speeding up the support for newly introducted syscalls (Hendrik Brueckner)

- Fix 'perf test' on filesystems where readdir() returns d_type == DT_UNKNOWN,
such as XFS (Jiri Olsa)

- Fix PERF_SAMPLE_RAW_DATA endianity handling for cross-arch tracepoint
processing (Jiri Olsa)

- Add __return suffix for return events in 'perf probe', streamlining
entry/exit tracing (Masami Hiramatsu)

- Improve support for versioned symbols in 'perf probe" (Masami Hiramatsu)

- Clarify error message about invalid 'perf probe' event names (Masami Hiramatsu)

- Fix check open filename arg using 'perf trace' in a 'perf test' entry for
systems using glibc >= 2.26, such as some ARM and s390 distros (Michael Petlan)

- Make method for obtaining the (normalized) architecture id for a
perf.data file or for the running system used by the annotation routines
generally available, next user will be for generating per arch errno
string tables to allow for pretty printing errno codes recorded in a
perf.data file in architecture A to be properly decoded on hardware
archictecture B. (Arnaldo Carvalho de Melo)

- Remove duplicate includes, found using scripts/checkincludes.pl (Pravin Shedge)

- s390 needs -fPIC, enable it, also revert a patch that supposedly did
that but instead enabled -fPIC for x86 (Hendrik Brueckner, Arnaldo Carvalho de Melo)
