Fix config warning:
warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)
and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!
by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

Fix by dropping I2C from the above dependency; logic is that this is not a

supports USB even is I2C is not selected.

James Bottomley reported [1] a massive power regression, due to the
enabling of semaphores by default in 3.5. A workaround for him is to
again disable semaphores. And indeed, his system has a very hard time
to enter rc6 with semaphores enabled.
Ben Widawsky run around with a kill-a-watt a lot and noticed:
- There are indeed a few rare systems that seem to have a hard time
entering rc6 when desktop-idle.
- One machine, The Indestructible Toshiba regressed in this behaviour
between 3.5 and 3.6 in a merge commit! So rc6 behaviour with the
current setting seems to be highly timing dependent and not robust
at all.
- The behaviour James reported wrt semaphores seems to be a freak
timing thing that only happens on his specific machine, confirming
that enabling semaphores shouldn't reduce rc6 residency.
Now furthermore the Google ChromeOS guys reported [2] a while ago that
at least on some machines a simply a blinking cursor can keep the gpu
turbo at the highest frequency. This is because the current rps limits
used on snb/ivb are highly asymmetric.
On the theory that gpu turbo and rc6 tuning values are related, we've
tried whether the much saner looking (since much less asymmetric) rps
tuning values used for hsw would also help entering rc6 more robustly.
And it seems to mostly work, and we don't really have the resources to
through-roughly tune things in any better way: The values from the
ChromeOS ppl seem to fare a bit worse for James' machine, so I guess
we better stick with something vpg (the gpu hw/windows group)
provided, hoping that they've done their jobs.

This commit removes the sk_rx_dst_set calls from
tcp_create_openreq_child(), because at that point the icsk_af_ops
field of ipv6_mapped TCP sockets has not been set to its proper final
value.
Instead, to make sure we get the right sk_rx_dst_set variant
appropriate for the address family of the new connection, we have
tcp_v{4,6}_syn_recv_sock() directly call the appropriate function
shortly after the call to tcp_create_openreq_child() returns.
This also moves inet6_sk_rx_dst_set() to avoid a forward declaration
with the new approach.

If a packet is emitted on one socket in one group of fanout sockets,
it is transmitted again. It is thus read again on one of the sockets
of the fanout group. This result in a loop for software which
generate packets when receiving one.
This retransmission is not the intended behavior: a fanout group
must behave like a single socket. The packet should not be
transmitted on a socket if it originates from a socket belonging
to the same fanout group.
This patch fixes the issue by changing the transmission check to
take fanout group info account.
