So Steven, this will break compilation on blackfin because that makes
____cacheline_aligned a NOP while we assume it will generate
__attribute__((__aligned__(SMP_CACHE_BYTES))) with the further
assumption that SMP_CACHE_BYTES >= 8.

Can you explain why blackfin chooses to break ____cacheline_align for
UP? We have the *_in_smp variants to distinguish these cases.
