todays tree is working on MMU microblaze correctly without any visible

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?
aaa - I was too fast and compiled noMMU tree for 09-12-02 not todays.
You can check it at http://www.monstr.eu/wiki/doku.php?id=log:log
The problem seems to me is away.
Thanks,

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.
