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) {
 80a9f48:       8b 48 08                mov    0x8(%eax),%ecx
 80a9f4b:       83 c2 08                add    $0x8,%edx
 80a9f4e:       8d 41 f4                lea    -0xc(%ecx),%eax
 80a9f51:       39 ca                   cmp    %ecx,%edx
 80a9f53:       8b 70 0c                mov    0xc(%eax),%esi
 80a9f56:       74 6a                   je     80a9fc2 <futex_wake+0xd2>
 80a9f58:       89 d9                   mov    %ebx,%ecx

 80a9f6e:       39 c3                   cmp    %eax,%ebx
 80a9f70:       74 4e                   je     80a9fc0 <futex_wake+0xd0>
 80a9f72:       89 f0                   mov    %esi,%eax
