Jiri Olsa 79b2fe5e75 perf tools: Fix proper buffer size for feature processing 
After Song Liu's segfault fix for pipe mode, Arnaldo reported following
error:

  # perf record -o - | perf script
  0x514 [0x1ac]: failed to process type: 80

It's caused by wrong buffer size setup in feature processing, which
makes cpu topology feature fail, because it's using buffer size to
recognize its header version.

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.
