The page fault handler (__do_page_fault()) basically has two sections: one for handling faults in the kernel portion of the address space and another for faults in the user portion of the address space. But, these two parts don't stick out that well. Let's make that more clear from code separation and naming. Pull kernel fault handling into its own helper, and reflect that naming by renaming spurious_fault() -> spurious_kernel_fault(). Also, rewrite the vmalloc() handling comment a bit. It was a bit stale and also glossed over the reserved bit handling.

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.
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.
