Other than triggering WARN_ON(), it doesn't cause any other problems, right? It's probably because SMP_CACHE_BYTES on that configuration is lower than 8. What is the value of SMP_CACHE_BYTES on the configuration? Also, doesn't the Linus's tree have the same problem?
The somewhat spurious WARN_ON() in percpu allocator should probably be just removed or bumped to check against PAGE_SIZE as SMP code does. The problem is that on UP even though the function takes @align parameter, it just ignores it. :-(
Thanks.
