There are extra codes in the CPU hotplug function to allocate rapl pmus. The generic PMU hotplug support is hard to be applied. As long as the rapl pmus can be allocated upfront for each die/socket, the code doesn't need to be implemented in the CPU hotplug function. Move the code to the init_rapl_pmus(), and allocate a PMU for each possible die/socket.

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.
