Ingo Molnar f575494d4a perf/core improvements and fixes:
BPF:
 
   Song Liu:
 
   - Introduce PERF_RECORD_KSYMBOL to allow tooling to notice the addition
     of new kernel symbols and be able to resolve samples in such symbols.
 
   - Introduce PERF_RECORD_BPF_EVENT to notify tooling about the loading
     and unloading of BPF programs, making them visible and allowing for
     the request of further information to allow for things like annotation.
 
   - Change the userspace perf tools to handle those new events and to
     synthesize them for pre-existing loaded BPF programs.
 
 Kernel:
 
   Arnaldo Carvalho de Melo:
 
   - Make perf_event_output() propagate the output() return, allowing
     users to check for -ENOSPC in the ring buffer.
 
 perf report:
 
   Thomas Richter:
 
   - Display arch specific diagnostic counter sets, starting with s390
     diagnostic counter sets.
 
 perf session:
 
   Jiri Olsa:
 
   - Introduce a reader object to prep for multithreaded processing
     of recorded events.
 
 Misc:
 
   Rasmus Villemoes:
 
   - Replace automatic const char[] variables by statics, to avoid
     initializing them at runtime, instead having them in .rodata,
     reducing code size.
 
   YueHaibing:
 
   - Remove duplicated workqueue.h include from perf_event.h
 
   Brajeswar Ghosh:
 
   - Remove some more duplicated headers.

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.
