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.
