x86 and powerpc (partially) enforce already CONFIG_HOTPLUG_CPU. On s390 it is enabled on all distributions by default since ages. The only exception is our zfcpdump kernel. However to simplify testing, enforce HOTPLUG_CPU. This was suggested by Paul McKenney, since his rcutorture test environments for CONFIG_SMP=y only support HOTPLUG_CPU=y. Suggested-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.
