Now that alloc->buffer points to the userspace vm_area rename buffer->data to buffer->user_data and rename local pointers that hold user addresses. Also use the "__user" tag to annotate all user pointers so sparse can flag cases where user pointer vaues are copied to kernel pointers. Refactor code to use offsets instead of user pointers.
