core:
Arnaldo Carvalho de Melo:
- Allow references to thread objects after__machine_exit(), fixing a bug with
'perf sched lat' where that happens, i.e. after perf_session__delete() we
still have references to threads that were in a linked list whose head was
freed in perf_session__delete(), causing a segfault, fix it.
Jiri Olsa:
- Do not rely on errno values for precise_ip fallback, fixing the default
use case for 'perf record' on some AMD servers, when no events are specified
and we try to use "cycles:P", i.e. with the maximum precision level.
BPF:
Song Liu:
- Assign proper ff->ph in perf_event__synthesize_features(), fixing a bug
when using pipe mode, i.e. 'perf record -o -'.
tools headers:
Arnaldo Carvalho de Melo:
- Sync kvm headers with the kernel sources
perf tests:
Seeteena Thoufeek:
- Fix record+probe_libc_inet_pton.sh for powerpc64, where without the
debuginfo package for the 'ping' utility we can't resolve its symbols,
so admit getting "[unknown]" for that backtrace line.
perf python:
Arnaldo Carvalho de Melo:
- Remove -fstack-protector-strong if clang doesn't have it, fixing the build
with clang on fedora:30, oracleline:7, centos:7.
perf jvmti:
Jiri Olsa:
- Address gcc string overflow warning for strncpy()
build:
Arnaldo Carvalho de Melo:
- Check if gettid() is available before providing helper, as recent
versions of glibc started to provide gettid().

README
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.
