Thomas Gleixner d8b5297f6d perf/core improvements and fixes:
BPF:
 
   Song Liu:
 
   - Add support for annotating BPF programs, using the PERF_RECORD_BPF_EVENT
     and PERF_RECORD_KSYMBOL recently added to the kernel and plugging
     binutils's libopcodes disassembly of BPF programs with the existing
     annotation interfaces in 'perf annotate', 'perf report' and 'perf top'
     various output formats (--stdio, --stdio2, --tui).
 
 perf list:
 
   Andi Kleen:
 
   - Filter metrics when using substring search.
 
 perf record:
 
   Andi Kleen:
 
   - Allow to limit number of reported perf.data files
 
   - Clarify help for --switch-output.
 
 perf report:
 
   Andi Kleen
 
   - Indicate JITed code better.
 
   - Show all sort keys in help output.
 
 perf script:
 
   Andi Kleen:
 
   - Support relative time.
 
 perf stat:
 
   Andi Kleen:
 
   - Improve scaling.
 
 General:
 
   Changbin Du:
 
   - Fix some mostly error path memory and reference count leaks found
     using gcc's ASan and UBSan.
 
 Vendor events:
 
   Mamatha Inamdar:
 
   - Remove P8 HW events which are not supported.

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.
