Here you say that you need only logical => physical. Logical => physical and physical => logical involve completely different mechanisms. So please be precise about this. To convert a logical address to a "struct page *" (which represents a physical page), you can use virt_to_page(), but it only works for kernel addresses (so it won't work with start_code and end_code that are user addresses). I don't know what is the clean way of converting a user virtual address to the associated physical address.
