Last argument in effective_prot() is u64 assuming pxd_val() returned value (all page table levels) is 64 bit. pxd_val() is very platform specific and its type should not be assumed in generic MM. Split effective_prot() into individual page table level specific callbacks which accepts corresponding pxd_t argument instead and then the subscribing platform (only x86) just derive pxd_val() from the entries as required and proceed as earlier.

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 reStructuredText 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.
