This commit adds an rcuperf module parameter named "holdoff" that defaults to 10 seconds if refperf is built in and to zero otherwise. The assumption is that all the CPUs are online by the time that the modprobe and insmod commands are going to do anything, and that normal systems will have all the CPUs online within ten seconds. Larger systems may take many tens of seconds or even minutes to get to this point, hence this being a module parameter instead of being a hard-coded constant.

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.
