The `OS_HINT` message is supposed to indicate that everything else
that is supposed to go into the deepest state has done so.
This assumption is invalid as:
1) The CPUs will still go in and out of the deepest state
2) Other devices may still run their `noirq` suspend routines
3) The LPS0 ACPI device will still run
To more closely mirror how this works on other operating systems,
move the `amd-pmc` suspend to the very last thing before the s2idle
loop via an lps0 callback.

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.
