Currently, the torture scripts rely on the initrd/init script to bring any extra CPUs online, for example, in the case where the kernel and qemu have different ideas about how many CPUs are present. This works, but is an unnecessary dependency on initrd, which needs to vary depending on the distro. This commit therefore causes torture_onoff() to check for additional CPUs, attempting to bring any found online. Errors are ignored, just as they are by the initrd/init script. Signed-off-by: Paul E.

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.
