When CONFIG_PTE_64BIT is set, pte_update() operates on 'unsigned long long' When CONFIG_PTE_64BIT is not set, pte_update() operates on 'unsigned long' In asm/page.h, we have pte_basic_t which is 'unsigned long long' when CONFIG_PTE_64BIT is set and 'unsigned long' otherwise. Refactor pte_update() using pte_basic_t. While we are at it, drop the comment on 44x which is not applicable to book3s version of pte_update().

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.
