[ Upstream commit 5095d5418193eb2748c7d8553c7150b8f1c44696 ] Linux PM core has a prepare() callback run before suspend. If the system is under high memory pressure, the resources may need to be evicted into swap instead. If the storage backing for swap is offlined during the suspend() step then such a call may fail. So move this step into prepare() to move evict majority of resources and update all non-pmops callers to call the same 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.
