Do netif_carrier_on() right after the IPv4 broadcast multicast group
is joined, rather than waiting for all of the initial set of multicast
group joins to finish.  This allows at least IPv4 traffic to limp
along on broken fabrics where not all multicast groups can be joined.

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.

An asynchronous event carries the port number that the event occurred

Jeremy Fitzhardinge suggested the use of -freg-struct-return, which does

kill dhcpd.

The problem is probably caused by commit with git identifier

Below is a patch which demotes many printk lines to KERN_DEBUG from
KERN_INFO.  It should help stop the spamming of logs with messages in
which users are not interested nor is there any action that users should
take.  It also promotes some KERN_INFO to KERN_ERR such as when there
are improper attempts to register/unregister security modules.

A similar patch was discussed a while back on list:
http://marc.theaimsgroup.com/?t=116656343500003&r=1&w=2
This patch addresses almost all of the issues raised.  I believe the
only advice not taken was in the demoting of messages related to
undefined permissions and classes.
