This adds a set of list macros that make handling of list protected
by RCU simpler. The interfaces added are -

list_add_rcu
list_add_tail_rcu
	- Adds an element by taking care of memory barrier (wmb()).

list_del_rcu
	- Deletes an element but doesn't re-initialize the pointers in
	  the element for supporting RCU based traversal.

list_for_each_rcu
__list_for_each_rcu
	- Traversal of RCU protected list - takes care of memory barriers
	  transparently.

This first RCU helper patch adds a read_barrier_depends() primitive
to all archs which is NOP for archs that doesn't require an rmb()
for data dependent reads when writes are ordered using a wmb().
In reality, only alpha requires an rmb(), the rest are NOPs.
It is likely to be necessary in most situations that would use RCU.
Please apply.

 Description :

Sometime ago, during a discussion on lock-free lookups, it was
agreed that an additional memory barrier interface,
read_barrier_depends() that is lighter than an rmb(),
is necessary to make sure that data-dependent reads are not
re-ordered over this barrier. For many processors, data-dependency
enforces order, so this interface is a NOP, but for those that don't
(like alpha), it can be a rmb().

For example, the following code would force ordering (the initial
value of "a" is zero, "b" is one, and "p" is "&a"):

    CPU 0                           CPU 1

    b = 2;
    memory_barrier();
    p = &b;                         q = p;
                                    read_barrier_depends();
                                    d = *q;

because the read of "*q" depends on the read of "p" and these
two reads should be separated by a read_barrier_depends().  However,
the following code, with the same initial values for "a" and "b":

    CPU 0                           CPU 1

    a = 2;
    memory_barrier();
    b = 3;                          y = b;
                                    read_barrier_depends();
                                    x = a;

does not enforce ordering, since there is no data dependency between
the read of "a" and the read of "b".  Therefore, on some CPUs, such
as Alpha, "y" could be set to 3 and "x" to 0.  rmb()
needs to be used here, not read_barrier_depends().

This fixes a 'used but not declared' compile error

It ends up trying to list_del() from an uninitialized
list_head.

- Ignore queries for invalid addresses
- MLD for link-local addresses

- Change {udp,raw}_sendmsg to ip_append_data, work done
by Maxim Giryaev <gem@asplinux.ru>
- Get rid of ip_build_xmit() and helper functions.
Nobody uses it anymore.

kill the machine.

Damn I hate people who kill the machine for no good reason.

A cloned bio still needs destructor set (and should clear bi_io_vec as
well), this was broken when Jens rewrote bio_alloc() recently.

This should now be OK with the mempool_alloc failing, and initialises
bi_io_vec = NULL for nr_iovecs = 0.
