pte_user() may return 'false' when a user page is PAGE_NONE. In that case it is still a user page and needs to be handled as such. So use is_kernel_addr() instead. And remove "user" text from ptdump as ptdump only dumps kernel tables. Note: no change done for book3s/64 which still has it 'priviledge' bit.

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.
