If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann commit 5b57167749274961baf15ed1f05a4996b3ab0487 upstream. The sw842 library code was merged in linux-4.1 and causes a very rare randconfig failure when CONFIG_CRC32 is not set: lib/built-in.o: In function `sw842_compress': oid_registry.c:(.text+0x12ddc): undefined reference to `crc32_be' lib/built-in.o: In function `sw842_decompress': oid_registry.c:(.text+0x137e4): undefined reference to `crc32_be' This adds an explict 'select CRC32' statement, similar to what the other users of the crc32 code have. In practice, CRC32 is always enabled anyway because over 100 other symbols select it.
