Richard Gong 7cad1c40ef ACPI: processor idle: Allow playing dead in C3 state
commit d6b88ce2eb9d2698eb24451eb92c0a1649b17bb1 upstream.

When some cores are disabled on AMD platforms, the system will no longer
be able to enter suspend-to-idle s0ix.

Update to allow playing dead in C3 state so that the CPUs can enter the
deepest state on AMD platforms.

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.
