xgene_enet_get_ring_size() returns a negative value in case of an error,
but its only caller in xgene_enet_create_desc_ring() currently uses the
return value directly as u32. Instead, check for a negative value first and
error out in case. Also move the call to xgene_enet_get_ring_size() before
devm_kzalloc() so we don't need to free anything in the error path.

This fixes the following issue reported by the Coverity Scanner:

** CID 1231336:  Improper use of negative value  (NEGATIVE_RETURNS)

We don't know right timestamp for repaired skb-s. Wrong RTT estimations
isn't good, because some congestion modules heavily depends on it.

This patch adds the TCPCB_REPAIRED flag, which is included in
TCPCB_RETRANS.

Thanks to Eric for the advice how to fix this issue.

Intel Wired LAN Driver Updates 2014-08-12

This series contains updates to i40e and e1000e.

Lucas provides a fix for i40e to resolve a compile issue where a header

Wei Yongjun provides a fix for i40e to resolve a sparse warning, where
a non-static function should be static.

Julia Lawall provides a fix for i40e which was found using Coccinelle,
where there was a typo in the name of the type given to sizeof().

Rickard Strandqvist provides a fix for i40e to replace the use of
strncpy() with strlcpy() to avoid strings that lack null termination.

Jean Sacren provides two e1000e fixes, first is a comment fix and second
removes an excessive space character in a debug message.

xen-netback: synchronisation between core driver and netback

The zero-copy netback has far more interactions with core network driver than
the old copying backend. One significant thing is that netback now relies on
a callback from core driver to correctly release resources.

However correct synchronisation between core driver and netback is missing.
Currently netback relies on a loop to wait for core driver to release
resources. This is proven not enough and erroneous recently, partly due to code
structure, partly due to missing synchronisation. Short-live domains like
OpenMirage unikernels can easily trigger race in backend, rendering backend
unresponsive.

This patch series aims to slove this issue by introducing proper
synchronisation between core driver and netback.

Chagges in v4:
* avoid using wait queue
* remove dedicated loop for netif_napi_del
* remove unnecessary check on callback

that the tskey is set for the fragment in which the tskey falls

One should not call blocking primitives inside a wait loop, since both
require task_struct::state to sleep, so the inner will destroy the
outer state.

sigd_enq() will possibly sleep for alloc_skb().  Move sigd_enq() before
prepare_to_wait() to avoid sleeping while waiting interruptibly.  You do
not actually need to call sigd_enq() after the initial prepare_to_wait()
because we test the termination condition before calling schedule().

Pull x86/apic updates from Thomas Gleixner:
 "This is a major overhaul to the x86 apic subsystem consisting of the
  following parts:

   - Remove obsolete APIC driver abstractions (David Rientjes)

   - Use the irqdomain facilities to dynamically allocate IRQs for
     IOAPICs.  This is a prerequisite to enable IOAPIC hotplug support,
     and it also frees up wasted vectors (Jiang Liu)

   - Misc fixlets.

  Despite the hickup in Ingos previous pull request - caused by the
  missing fixup for the suspend/resume issue reported by Borislav - I
  strongly recommend that this update finds its way into 3.17.  Some
  history for you:

  This is preparatory work for physical IOAPIC hotplug.  The first
  attempt to support this was done by Yinghai and I shot it down because
  it just added another layer of obscurity and complexity to the already
  existing mess without tackling the underlying shortcomings of the
  current implementation.

  After quite some on- and offlist discussions, I requested that the
  design of this functionality must use generic infrastructure, i.e.
  irq domains, which provide all the mechanisms to dynamically map linux
  interrupt numbers to physical interrupts.

  Jiang picked up the idea and did a great job of consolidating the
  existing interfaces to manage the x86 (IOAPIC) interrupt system by
  utilizing irq domains.

  The testing in tip, Linux-next and inside of Intel on various machines
  did not unearth any oddities until Borislav exposed it to one of his
  oddball machines.  The issue was resolved quickly, but unfortunately
  the fix fell through the cracks and did not hit the tip tree before
  Ingo sent the pull request.  Not entirely Ingos fault, I also assumed
  that the fix was already merged when Ingo asked me whether he could
  send it.

  Nevertheless this work has a proper design, has undergone several
  rounds of review and the final fallout after applying it to tip and
  integrating it into Linux-next has been more than moderate.  It's the
  ground work not only for IOAPIC hotplug, it will also allow us to move
  the lowlevel vector allocation into the irqdomain hierarchy, which
  will benefit other architectures as well.  Patches are posted already,
  but they are on hold for two weeks, see below.

  I really appreciate the competence and responsiveness Jiang has shown
  in course of this endavour.  So I'm sure that any fallout of this will
  be addressed in a timely manner.

  FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen
  duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA
  will have a look at the hopefully zero fallout until I'm back"

If do_journal_release() races with do_journal_end() which requeues
delayed works for transaction flushing, we can leave work items for
flushing outstanding transactions queued while freeing them. That
results in use after free and possible crash in run_timers_softirq().

Fix the problem by not requeueing works if superblock is being shut down
(MS_ACTIVE not set) and using cancel_delayed_work_sync() in
do_journal_release().

Additionally E1000_ERR_HOST_INTERFACE_COMMAND is supposed to be
