The single routine has a very confusing scheme to advance to the next child MR when working on an implicit parent. This scheme can only be used when working with an implicit parent and must not be triggered when working on a normal MR. Re-arrange things by directly putting all the single-MR stuff into one function and calling it in a loop for the implicit case. Simplify some of the error handling in the new pagefault_real_mr() to remove unneeded gotos.

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.
