He Zhe 88b88dd7d8 perf bench internals inject-build-id: Fix trap divide when collecting just one DSO
[ Upstream commit d9180e23fb ]

'perf bench internals inject-build-id' suffers from the following error when
only one DSO is collected.

  # perf bench internals inject-build-id -v
    Collected 1 DSOs
  traps: internals-injec[2305] trap divide error
  ip:557566ba6394 sp:7ffd4de97fe0 error:0 in perf[557566b2a000+23d000]
    Build-id injection benchmark
    Iteration #1
  Floating point exception

This patch removes the unnecessary minus one from the divisor which also
corrects the randomization range.

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.
