Hello, In the 2.4.x kernel, can I apply the virt_to_page() macro to any address allocated by __get_free_pages() (i.e. when calling ret = __get_free_pages(flags, order), to any address in the interval [retval, 2^order * PAGE_SIZE])? In other words are those addresses guaranteed to be kernel logical addresses (i.e. between PAGE_OFFSET and PAGE_OFFSET + high_memory (on ix86))? I know that in the 2.2.x kernel this used to be the case (i.e. __get_free_pages() returned kernel logical addresses, to which virt_to_page() could be applied), but I don't quite understand the memory managment of 2.4.x yet.
