asm-generic: xor: mark static functions as __maybe_unused
The asm-generic/xor.h header file is nasty and defines static functions that are not inline. The header file is include by the ARM version of asm/xor.h, which uses some but not all of the symbols defined there. Marking the extraneous functions as __maybe_unused lets gcc drop them without complaining. Without this patch, building iop13xx_defconfig results in: include/asm-generic/xor.h:696:34: warning: 'xor_block_8regs_p' defined but not used [-Wunused-variable] include/asm-generic/xor.h:704:34: warning: 'xor_block_32regs_p' defined but not used [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Dan Williams <dan.j.williams@gmail.com> Cc: Neil Brown <neilb@suse.de>
