This fixes a regression introduced byfaa16bc404("lib: Use existing define with polynomial"). The cleanup added a dependency on include/linux, which broke the PowerPC boot wrapper/decompresser when KERNEL_XZ is enabled: BOOTCC arch/powerpc/boot/decompress.o In file included from arch/powerpc/boot/../../../lib/decompress_unxz.c:233, from arch/powerpc/boot/decompress.c:42: arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:10: fatal error: linux/crc32poly.h: No such file or directory #include <linux/crc32poly.h> ^~~~~~~~~~~~~~~~~~~ The powerpc decompresser is a hairy corner of the kernel. Even while building a 64-bit kernel it needs to build a 32-bit binary and therefore avoid including files from include/linux. This allows users of the xz library to avoid including headers from 'include/linux/' while still achieving the cleanup of the magic number.

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.
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.
