pm_restrict_gfp_mask()/pm_restore_gfp_mask() only used in power, let's move them out of page_alloc.c. Adding a general gfp_has_io_fs() function which return true if gfp with both __GFP_IO and __GFP_FS flags, then use it inside of pm_suspended_storage(), also the pm_suspended_storage() is moved into suspend.h.

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.
