Juergen Gross 84bbabc3a4 x86/mm: Fix dump pagetables for 4 levels of page tables 
Commit fdd3d8ce0e ("x86/dump_pagetables: Add support for 5-level
paging") introduced an error for dumping with only 4 levels by setting
PGD_LEVEL_MULT to a wrong value.

This is leading to e.g. addresses printed as "(null)" for ranges:

  x86/mm: Found insecure W+X mapping at address (null)/(null)

Make PGD_LEVEL_MULT a multiple of PTRS_PER_P4D instead of PTRS_PER_PUD

Fixes: fdd3d8ce0e ("x86/dump_pagetables: Add support for 5-level paging")

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
