Maybe just have two copies of the function body?

 static __always_inline enum kmalloc_cache_type kmalloc_type(gfp_t flags)
{
#ifndef CONFIG_ZONE_DMA
	return flags & __GFP_RECLAIMABLE ? KMALLOC_RECLAIM : KMALLOC_NORMAL;
#else
	if (likely((flags & (__GFP_DMA | __GFP_RECLAIMABLE)) == 0))
		return KMALLOC_NORMAL;
	return flags & __GFP_DMA ? KMALLOC_DMA : KMALLOC_RECLAIM;
#endif
}

	David
