Ingo Molnar 9835bf7ff8 perf/core improvements and fixes:
perf test:
 
 - Add watchpoint entry (Ravi Bangoria)
 
 Build fixes:
 
 - Initialize perf_data_file fd field to fix building the CTF (trace format)
   converter with with gcc 4.8.4 on Ubuntu 14.04 (Jérémie Galarneau)
 
 - Use -Wno-redundant-decls to build with PYTHON=python3 to
   build the python binding, fixing the build in systems such
   as Clear Linux (Arnaldo Carvalho de Melo)
 
 Hardware tracing:
 
 - Suppress AUX/OVERWRITE records (Alexander Shishkin)
 
 Infrastructure:
 
 - Adopt PTR_ERR_OR_ZERO from the kernel and use it in
   the bpf-loader instead of open coded equivalent (Ding Xiang)
 
 - Improve the event ordering code to make it clear and fix
   a bug related to freeing of events when using pipe mode
   from 'record' to 'inject' (Jiri Olsa)
 
 - Some prep work to facilitate per-cpu threads to write
   record data to per-cpu files (Jiri Olsa)

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
