hi all,
i was a little confused by linux/ia64 mm; as i know, linux requires
physical memory to be mapped contiguously to kernel space( don't care
highmem); and PAGE_OFFSET is defined to 0xe000000000000000 in linux/ia64;
that's region 7, its page size is fixed to 64M(2.4.12). how could
__get_free_pages() allocate such a big _page_? it's absolutely impossible.
so i think i made a big mistake somewhere, would someone help me out?
thx :-)
