Add a new __xfs_filemap_fault helper that implements all four page fault callouts, and make these methods themselves small stubs that set the correct write_fault flag, and exit early for the non-DAX case for the hugepage related ones. Also remove the extra size checking in the pfn_fault path, which is now handled in the core DAX code. Life would be so much simpler if we only had one method for all this.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
