This is spewing 800+ warnings on ape6evm_defconfig on ARM that doesn't
have CONFIG_BLOCK enabled, since struct bio_vec is protected by that
in include/linux/blk_types.h. I guess it could be argued that those
ifdefs could be removed, but still:
../../arch/arm/include/asm/io.h:378:24: warning: its scope is only
this definition or declaration, which is probably not what you want
[enabled by default]
