Ingo Molnar d1d59b8179 perf/urgent fixes:
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.
