Slightly worrying... this should be CONFIG_HAVE_JUMP_LABEL, right? How did
you manage to test this code?

In <linux/jump_label.h> we have:

#if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL)

[...]

# include <asm/jump_label.h>
# define HAVE_JUMP_LABEL
#endif	/* CC_HAVE_ASM_GOTO && CONFIG_JUMP_LABEL */

Phew, that explains things! Cheers, Steve.
