The hierarchical PM domain topology are currently disabled on a PREEMPT_RT based configuration. As a first step to enable it to be used, let's try to attach the CPU devices to their PM domains on PREEMPT_RT. In this way the syscore ops becomes available, allowing the PM domain topology to be managed during s2ram. For the moment let's leave the support for CPU hotplug outside PREEMPT_RT, as it's depending on using runtime PM. For s2ram, this isn't a problem as all CPUs are managed via the syscore ops.

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 reStructuredText 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.
