Add lookup_address_in_pgd_attr() doing the same as the already existing lookup_address_in_pgd(), but returning the effective settings of the NX and RW bits of all walked page table levels, too. This will be needed in order to match hardware behavior when looking for effective access rights, especially for detecting writable code pages. In order to avoid code duplication, let lookup_address_in_pgd() call lookup_address_in_pgd_attr() with dummy parameters.

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.
