Well (BTW nearly similar to the result of "objdump -d -S linux" ), but anyway 
here it is :

        spin_lock(&hb->lock);
        head = &hb->chain;

        plist_for_each_entry_safe(this, next, head, list) {

 80a9f4b:       83 c2 08                add    $0x8,%edx
 80a9f4e:       8d 41 f4                lea    -0xc(%ecx),%eax
