Do netif_carrier_on() right after the IPv4 broadcast multicast group

This patch fixes two issues reported by Roland Dreier and Christoph Hellwig:
- Mismatched sync/locking between completion handler and destroy cq We
introduced a counter nr_events per cq to track number of irq events
seen. This counter is incremented when an event queue entry is seen
and decremented after completion handler has been called regardless
if scaling code is active or not. Note that nr_callbacks tracks
number of events assigned to a cpu and both counters can potentially
diverge.
The sync between running completion handler and destroy cq is done
by using the global spin lock ehca_cq_idr_lock.
- Replace yield by wait_event on the counter above to become zero.

[SCTP]: Fix connection hang/slowdown with PR-SCTP
The problem that this patch corrects happens when all of the following
conditions are satisfisfied:
1. PR-SCTP is used and the timeout on the chunks is set below RTO.Max.
2. One of the paths on a multihomed associations is brought down.
In this scenario, data will expire within the rto of the initial
transmission and will never be retransmitted. However this data still
fills the send buffer and is counted against the association as outstanding
data. This causes any new data not to be sent and retransmission to not
happen.
The fix is to discount the abandoned data from the outstanding count and
peers rwnd estimation. This allows new data to be sent and a retransmission
timer restarted. Even though this new data will most likely expire within
the rto, the timer still counts as a strike against the transport and forces
the FORWARD-TSN chunk to be retransmitted as well.

[PATCH] genirq: Mask irqs when migrating them.
move_native_irqs tries to do the right thing when migrating irqs
by disabling them. However disabling them is a software logical
thing, not a hardware thing. This has always been a little flaky
and after Ingo's latest round of changes it is guaranteed to not
mask the apic.
So this patch fixes move_native_irq to directly call the mask and
unmask chip methods to guarantee that we mask the irq when we
are migrating it. We must do this as it is required by
all code that call into the path.
Since we don't know the masked status when IRQ_DISABLED is
set so we will not be able to restore it. The patch makes the code
just give up and trying again the next time this routing is called.

[PATCH] x86_64 irq: Safely cleanup an irq after moving it.
The problem: After moving an interrupt when is it safe to teardown
the data structures for receiving the interrupt at the old location?
With a normal pci device it is possible to issue a read to a device
to flush all posted writes. This does not work for the oldest ioapics
because they are on a 3-wire apic bus which is a completely different
data path. For some more modern ioapics when everything is using
front side bus delivery you can flush interrupts by simply issuing a
read to the ioapic. For other modern ioapics emperical testing has
shown that this does not work.
So it appears the only reliable way to know the last of the irqs from an
ioapic have been received from before the ioapic was reprogrammed is to
received the first irq from the ioapic from after it was reprogrammed.
Once we know the last irq message has been received from an ioapic
into a local apic we then need to know that irq message has been
processed through the local apics.

[ARM] 4224/2: allow XIP kernel to boot again
Since commit
2552fc27ff79b10b9678d92bcaef21df38bb7bb6 XIP kernels failed
to boot because (_end - PAGE_OFFSET - 1) is much smaller than the size
of the kernel text and data in the XIP case, causing the kernel not to
be entirely mapped.
Even in the non-XIP case, the use of (_end - PAGE_OFFSET - 1) is wrong
because it produces a too large value if TEXT_OFFSET is larger than 1MB.
Finally the original code was performing one loop too many.
Let's break the loop when the section pointer has passed the last byte
of the kernel instead.

USB: export autosuspend delay in sysfs
This patch (as861) adds sysfs attributes to expose the autosuspend
delay value for each USB device. If the user changes the delay from 0
(no autosuspend) to a positive value, an autosuspend is attempted.

sysfs: allow attributes to be added to groups
This patch (as860) adds two new sysfs routines:
sysfs_add_file_to_group() and sysfs_remove_file_from_group().
A later patch adds code that uses the new routines.

USB: make autosuspend delay a module parameter
This patch (as859) makes the default USB autosuspend delay a module
parameter of usbcore. By setting the delay value at boot time, users
will be able to prevent the system from autosuspending devices which
for some reason can't handle it.
The patch also stores the autosuspend delay as a per-device value. A
later patch will allow the user to change the value, tailoring the
delay for each individual device. A delay value of 0 will prevent
autosuspend.

This adds a blacklist to the USB core to handle some autosuspend and
