firstly, it's a little waste to _must_ steal 1M for some board with less 
memory such as 512M memory;

secondly, if we do not support the section unaligned mapping, we should 
remove the alloc_init_pte() in alloc_init_pmd(),
add a comment to tell that we do not support the section unaligned mapping.
