This is a purely mechanical split of the copy_one_pte() function. It's not immediately obvious when looking at the diff because of the indentation change, but the way to see what is going on in this commit is to use the "-w" flag to not show pure whitespace changes, and you see how the first part of copy_one_pte() is simply lifted out into a separate function. And since the non-present case is marked unlikely, don't make the new function be inlined. Not that gcc really seems to care, since it looks like it will inline it anyway due to the whole "single callsite for static function" logic. In fact, code generation with the function split is almost identical to before. But not marking it inline is the right thing to do. This is pure prep-work and cleanup for subsequent changes.

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.
