Unadorned '%p' has restrictive policies these days, such that it usually just prints garbage at early boot (see Documentation/core-api/printk-formats.rst, "kernel will print ``(ptrval)`` until it gathers enough entropy"). Annotating with %pK (for "kernel pointer") allows the kptr_restrict sysctl to control printing policy better. We might just as well drop this message entirely, but this fix was easy enough for now.

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.
