commit88e0a74902upstream. Commit c164fbb40c43f("x86/mm: thread pgprot_t through init_memory_mapping()") mistakenly used __pgprot() which doesn't respect __default_kernel_pte_mask when setting PUD mapping. Fix it by only setting the one bit we actually need (PSE) and leaving the other bits (that have been properly masked) alone.

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.
