I finally nailed its origin down to /usr/include/linux/compiler.h
In that file, we have

/* Somewhere in the middle of the GCC 2.96 development cycle, we implemented
   a mechanism by which the user can annotate likely branch directions and
   expect the blocks to be reordered appropriately.  Define __builtin_expect
   to nothing for earlier compilers.  */

#if __GNUC__ == 2 && __GNUC_MINOR__ < 96
#define __builtin_expect(x, expected_value) (x)

#define likely(x)       __builtin_expect((x),1)
#define unlikely(x)     __builtin_expect((x),0)

Notice that those defines are not guarded by __KERNEL__.

I would suggest that, Axiom spells its C MACROS all in CAPS, and
prefix them with AXIOM_.
Is that workable?
