The status interrupt flag should be cleared before processing,
not afterwards to avoid race. Need to process in poll routine
even if no new interrupt status. This is a normal occurrence when
more than 64 frames (NAPI weight) are processed in one poll routine.

This is a backout of earlier patch.
The whole rescheduling hack was a bad idea. It doesn't really solve
the problem and it makes the code more complicated for no good reason.

Taking the cpu hotplug semaphore in a normal events workqueue
is unsafe because other tasks can wait for any workqueues with
it hold. This results in a deadlock.
Move the DBS timer into its own work queue which is not
affected by other work queue flushes to avoid this.
Has been acked by Venkatesh.

Extend the support of attribute groups in class_device's to allow
groups to be created as part of the registration process. This allows
network device's to avoid race between registration and creating
groups.
Note that unlike attributes that are a property of the class object,
the groups are a property of the class_device object. This is done
because there are different types of network devices (wireless for
example).

The problem here is that the bcm34xx driver and the ieee80211
stack do not agree on what channels are possible for 802.11a.
The ieee80211 stack only wants channels between 34 and 165, while
the bcm43xx driver accepts anything from 0 to 200. I made the
bcm43xx driver comply with the ieee80211 stack expectations, by
using the proper constants.

Address the issue of EDAC/BIOS coexistence for the e752x chip-sets.
We have found a problem where the BIOS will start the system with the error
registers (dev0:fun1) hidden and assuming it has exclusive access to them.
The edac driver violates this assumption.
The workaround this patch offers is to honor the hidden-ness as an
indication that it is not safe to use those registers.
