perf record:
Stephane Eranian:
- Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
so reset both to zero.
Arnaldo Carvalho de Melo:
- Don't warn about not being able to read kernel maps (kallsyms, etc) when
kernel samples aren't being collected.
perf list:
Kim Phillips:
- Allow plurals for metric, metricgroup., i.e.:
$ perf list metrics
was showing nothing, which is very confusing, make it work like:
$ perf stat metric
perf stat:
Andi Kleen:
- Free memory access/leaks detected via valgrind, related to metrics.
Libraries:
libperf:
Jiri Olsa:
- Move more stuff from tools/perf, this time a first stab at moving perf_mmap
methods.
libtracevent:
Steven Rostedt (VMware):
- Round up in tep_print_event() time precision.
Tzvetomir Stoyanov (VMware):
- Man pages for event print and related and plugins APIs.
- Move traceevent plugins in its own subdirectory.
Feature detection:
Thomas Richter:
- Add detection of java-11-openjdk-devel package, in addition to the older
versions supported.
Architecture specific:
S/390:
Thomas Richter (2):
- Include JVMTI support for s390
Vendor events:
AMD:
Kim Phillips:
- Add L3 cache events for Family 17h.
- Remove redundant '['.
PowerPC:
Mamatha Inamdar:
- Remove P8 HW events which are not supported.
Cleanups:
Arnaldo Carvalho de Melo:
- Remove needless headers, add needed ones, move things around to reduce the
headers dependency tree, speeding up builds by not doing needless compiles
when unrelated stuff gets changed.
- Ditch unused code that was dragging headers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
