You cannot include <generated/compile.h> here because it is generated in init/Makefile but there is no guarantee that it happens before arch/powerpc/mm/nohash/kaslr_booke.c is compiled for parallel builds. The places where you can reliably include <generated/compile.h> are: - init/ (because init/Makefile can specify the dependency) - arch/*/boot/ (because it is compiled after vmlinux) Commitf231e43333("hexagon: get rid of #include <generated/compile.h>") fixed the last breakage at that time, but powerpc re-added this. <generated/compile.h> was unneeded because 'build_str' is almost the same as 'linux_banner' defined in init/version.c Let's copy the solution from MIPS.

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.
