Commitc9b5ad546e"s390/mm: tag normal pages vs pages used in page tables" accidentally changed the logic in arch_set_page_states(), which is used by the suspend/resume code. set_page_stable(page, order) was changed to set_page_stable_dat(page, 0). After this, only the first page of higher order pages will be set to stable, and a write to one of the unstable pages will result in an addressing exception. Fix this by using "order" again, instead of "0".

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
