    Pull kvm fixes from Paolo Bonzini:
     "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"
