Preparatory patch for the source merge of arch/i386 and arch/x86_64
into arch/x86. This allows to keep the original arch directories as
stubs for the main Makefiles, Kconfigs et. al during the transition
phase while having the code in the new arch/x86 directory.

Our _GLOBAL macro does a ".align 2" so the alignment is fine for 32
bit, but on 64 bit it is possible for it to end up only 4 byte aligned.
I don't know if it matters, but it can't hurt to 8 byte align it.
It also means that when we build with --emit_relocs, none of our 64 bit
relocations are to misaligned places.

As discussed before, this patch provides userland with a way to access
relevant options in Router Advertisements, after they are processed
and validated by the kernel. Extra options are processed in a generic
way; this patch only exports RDNSS options described in RFC5006, but
support to control which options are exported could be easily added.
A new rtnetlink message type is defined, to transport Neighbor
Discovery options, along with optional context information. At the
moment only the address of the router sending an RDNSS option is
included, but additional attributes may be later defined, if needed by
new use cases.

This patch make processing netlink user -> kernel messages synchronious.
This change was inspired by the talk with Alexey Kuznetsov about current
netlink messages processing. He says that he was badly wrong when introduced
asynchronious user -> kernel communication.
The call netlink_unicast is the only path to send message to the kernel
netlink socket. But, unfortunately, it is also used to send data to the
user.
Before this change the user message has been attached to the socket queue
and sk->sk_data_ready was called. The process has been blocked until all
pending messages were processed. The bad thing is that this processing
may occur in the arbitrary process context.
This patch changes nlk->data_ready callback to get 1 skb and force packet
processing right in the netlink_unicast.
Kernel -> user path in netlink_unicast remains untouched.
EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock
drop, but the process remains in the cycle until the message will be fully
processed. So, there is no need to use this kludges now.

There are currently two ways to determine whether the netlink socket is a
kernel one or a user one. This patch creates a single inline call for
this purpose and unifies all the calls in the af_netlink.c
No similar calls are found outside af_netlink.c.

There is no need to process outstanding netlink user->kernel packets
during rtnl_unlock now. There is no rtnl_trylock in the rtnetlink_rcv
anymore.
Normal code path is the following:
netlink_sendmsg
netlink_unicast
netlink_sendskb
skb_queue_tail
netlink_data_ready
rtnetlink_rcv
mutex_lock(&rtnl_mutex);
netlink_run_queue(sk, qlen, &rtnetlink_rcv_msg);
mutex_unlock(&rtnl_mutex);
So, it is possible, that packets can be present in the rtnl->sk_receive_queue
during rtnl_unlock, but there is no need to process them at that moment as
rtnetlink_rcv for that packet is pending.
