- Introduce 'perf record --aio' to use asynchronous IO trace writing, disabled
by default (Alexey Budankov)

(kernel/userspace/hypervisor) and thus must first fallback lookups looking
at all map trees when trying to resolve symbols (Adrian Hunter)

warn the user about the former being nonsensical (Adrian Hunter)

- Fix 'perf test' entry where we expect 'sleep' to come in a PERF_RECORD_COMM
but instead we get 'coreutils' when sleep is provided by some versions of
the 'coreutils' package (Adrian Hunter)

- Introduce 'perf top --kallsyms file' to match 'perf report --kallsyms', useful
when dealing with BPF, where symbol resolution happens via kallsyms, not via
the default vmlinux ELF symtabs (Arnaldo Carvalho de Melo)

Go over the tools/ files that are maintained in Arnaldo's tree and
fix common typos: half of them were in comments, the other half

No change in functionality intended.

Committer notes:

This was split from a larger patch as there are code that is,
additionally, maintained outside the kernel tree, so to ease
cherry-picking and/or backporting, split this into multiple patches.

Just typos in comments, no need to backport, reducing the possibility of
possible backporting artifacts.

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 kernel side changes were:

- Modernize the kprobe and uprobe creation/destruction tooling ABIs:

The existing text based APIs (kprobe_events and uprobe_events in
tracefs), are naive, limited ABIs in that they require user-space
to clean up after themselves, which is both difficult and fragile
if the tool is buggy or exits unexpectedly. In other words they are
not really suited for modern, robust tooling.

So introduce a modern, file descriptor based ABI that does not have
these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
PMUs and extend the perf_event_open() syscall to create events with
a kprobe/uprobe attached to them. These [k,u]probe are associated
with this file descriptor, so they are not available in tracefs.

(Song Liu)

- Intel Cannon Lake CPU support (Harry Pan)

- Intel PT cleanups (Alexander Shishkin)

- Improve the performance of pinned/flexible event groups by using RB
trees (Alexey Budankov)

- Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
of hardware breakpoints, which new ABI variant massively speeds up
existing tooling that uses hardware breakpoints to instrument (and
debug) memory usage.

(Milind Chabbi, Jiri Olsa)

- Various Intel PEBS handling fixes and improvements, and other Intel
PMU improvements (Kan Liang)

- Various perf core improvements and optimizations (Peter Zijlstra)

- ... misc cleanups, fixes and updates.

There's over 200 tooling commits, here's an (imperfect) list of
highlights:

- 'perf annotate' improvements:

* Recognize and handle jumps to other functions as calls, which
improves the navigation along jumps and back. (Arnaldo Carvalho
de Melo)

* Add the 'P' hotkey in TUI annotation to dump annotation output
into a file, to ease e-mail reporting of annotation details.
(Arnaldo Carvalho de Melo)

* Add an IPC/cycles column to the TUI (Jin Yao)

* Improve s390 assembly annotation (Thomas Richter)

* Refactor the output formatting logic to better separate it into
interactive and non-interactive features and add the --stdio2
output variant to demonstrate this. (Arnaldo Carvalho de Melo)

- 'perf script' improvements:

* Add Python 3 support (Jaroslav Škarvada)

* Add --show-round-event (Jiri Olsa)

- 'perf c2c' improvements:

* Add NUMA analysis support (Jiri Olsa)

- 'perf trace' improvements:

* Improve PowerPC support (Ravi Bangoria)

- 'perf inject' improvements:

* Integrate ARM CoreSight traces (Robert Walker)

- 'perf stat' improvements:

* Add the --interval-count option (yuzhoujian)

* Add the --timeout option (yuzhoujian)

- 'perf sched' improvements (Changbin Du)

- Vendor events improvements :

* Add IBM s390 vendor events (Thomas Richter)

* Add and improve arm64 vendor events (John Garry, Ganapatrao
Kulkarni)

* Update POWER9 vendor events (Sukadev Bhattiprolu)

- Intel PT tooling improvements (Adrian Hunter)

- PMU handling improvements (Agustin Vega-Frias)

- Record machine topology in perf.data (Jiri Olsa)

- Various overwrite related cleanups (Kan Liang)

- Add arm64 dwarf post unwind support (Kim Phillips, Jean Pihet)

- ... and lots of other changes, cleanups and fixes, see the shortlog
