First, handle the normal retry failure in do_page_fault itself, since it's a simple return statement. That allows us to remove the "continue" special return code from mm_fault_error(). Once that's done, we can have an implementation much closer to x86 where we only call mm_fault_error() if VM_FAULT_ERROR is set and directly return.

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.
