    lib/xz: Put CRC32_POLY_LE in xz_private.h · 242cdad8
    Joel Stanley authored
    This fixes a regression introduced by faa16bc4 ("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.
    Fixes: faa16bc4 ("lib: Use existing define with polynomial")
