Pages used in scatterlist can be mapped page cache pages (and often are), so we must use flush_dcache_page here instead of the more limited flush_kernel_dcache_page that is intended for highmem pages only. Also remove the PageSlab check given that page_mapping_file as used by the flush_dcache_page implementations already contains that check.

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.
