[Linux-ia64] about linux/ia64 mm

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 :-)

rgds, tang
