Subject: do_swap_page() and !CONFIG_SWAP

Hello,

Is there any valid reason (except memory corruption) for do_swap_page() 
to be called in a x86_64 2.6.21.5 kernel where CONFIG_SWAP is not selected?

If not, does it make sense to put there something in lines of:

       print_bad_pte(vma, orig_pte, address);
       panic("unexpected swap pte - possible page table memory corruption\n");

?
