rtas_suspend_last_cpu() and related code perform a lot of work that isn't relevant to the hibernation workflow. All other CPUs are offline when called so there is no need to place them in H_JOIN or prod them on resume, nor is there need for retries or operations on shared state. Call the rtas_ibm_suspend_me() wrapper function directly from pseries_suspend_enter() instead of using rtas_suspend_last_cpu().

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.
