	I have a question for Rik, If the vmallocd memory is immediately
backed by physical pages by something like get_free_pages(), then why the 
need for vmalloc is there at all? I mean we may as well use kmalloc.  Is
it the case that vmalloc is used when one  is not too sure if required
contiguous physical memory will be available or not?
