Practically , version with kmalloc works, but  setup_arch and thus this 
function is called before mem_init, so I just wonder if kmalloc can 
handle this case. On the other hand, I don't like to deal with
alloc_bootmem() if mem_init_done!=1 and kmalloc otherwise (like ocp 
does) just for the temporary buffer.

But it's the only _right_ way (or I 've missed something) - sure I'll 
follow it.
