[BUG] 2.6.25-rc3-mm1 kernel panic while bootup on powerpc ()

I think this is the correct fix.

The NUMA fallback logic should be passing local_flags to kmem_get_pages() 
and not simply the flags.

Maybe a stable candidate since we are now simply 
passing on flags to the page allocator on the fallback path.
