pte_user() is now only used in pte_access_permitted() to check access on vmas. User flag is cleared to make a page unreadable. So rename it pte_read() and remove pte_user() which isn't used anymore. For the time being it checks _PAGE_USER but in the near futur all plateforms will be converted to _PAGE_READ so lets support both for now.

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.
