Hi, I am experiencing something strange about pages and ptes on x86. I am calling alloc_pages() with order = 1 (should be 2 pages). This returns a struct page with virtual address c7800000 (returned by page_address()). Now I call lookup_address() on the same address, and the pte is located at c0438c78. So far, so good. But if I try to call lookup_address() on the next page (i.e. address 7801000), this returns a pte which is located at c7800004. How can this happen? This would mean that the pte is inside the previous page, which is nonsense, since it was just returned to me by the page allocator. Does anybody know immediately what I am doing wrong here? Help is appreciated. Thanks.
