if we need to remap the address which returned from ioremap to our user-space, we can use remap_page_range in kernel2.4. but now the relevant virtual memory area (VMA) pointer must be passed as the first parameter of remap_page_range(), which vma can we pass to remap_page_range now ?
thx for your's reply.
