The pseries hibernate code calls post_mobility_fixup() which is sort of a dumping ground of fixups that need to run after resuming from suspend regardless of whether suspend was a hibernation or a migration. Calling post_mobility_fixup() from pseries_suspend_enable_irqs() runs this code early in resume with devices suspended and only one CPU up, while the much more commonly used migration case runs these fixups in a more typical process context. Call post_mobility_fixup() after the suspend core returns a success status to the hibernate sysfs store method and remove pseries_suspend_enable_irqs().

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.
