This fixes a regression introduced by faa16bc404d72a5 ("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.
