  kvm: vfio: fix unregister kvm_device_ops of vfio (2014-10-24 13:30:47 +0200)

----------------------------------------------------------------
This is a pretty large update.  I think it is roughly as big
as what I usually had for the _whole_ rc period.

There are a few bad bugs where the guest can OOPS or crash the host.  We
have also started looking at attack models for nested virtualization;
bugs that usually result in the guest ring 0 crashing itself become
more worrisome if you have nested virtualization, because the nested
guest might bring down the non-nested guest as well.  For current
uses of nested virtualization these do not really have a security
impact, but you never know and bugs are bugs nevertheless.

A lot of these bugs are in 3.17 too, resulting in a large number of
stable@ Ccs.  I checked that all the patches apply there with no
conflicts.
