Thomas Richter 2187d87eac perf report: Add s390 diagnosic sampling descriptor size 
On IBM z13 machine types 2964 and 2965 the descriptor
sizes for sampling and diagnostic sampling entries
might be missing in the trailer entry and are set to zero.

This leads to a perf report failure when processing diagnostic
sampling entries.

This patch adds missing descriptor sizes when the trailer entry
contains zero for these fields.

Output before:
  [root@s38lp82 perf]#  ./perf report --stdio | fgrep Samples
  0xabbf0 [0x8]: failed to process type: 68
  Error:
  failed to process sample
  [root@s38lp82 perf]#

Output after:
  [root@s38lp82 perf]#  ./perf report --stdio | fgrep Samples
  # Total Lost Samples: 0
  # Samples: 3K of event 'SF_CYCLES_BASIC_DIAG'
  # Samples: 162  of event 'CF_DIAG'
  [root@s38lp82 perf]#

Fixes: 2b1444f2e2 ("perf report: Add raw report support for s390 auxiliary trace")

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.
