This patch fixes the compile breakage :

1287cb3fa85c KVM: PPC: Book3S: Move vcore definition to end of kvm_arch

You might want to also add  this one :

c77dcacb3975 KVM: Move more code under CONFIG_HAVE_KVM_IRQFD

With these two extra patches, utopic kernel 3.16.0-13.19  compiles, boots 
and virtualizes  KVM HV guests (LE and BE) as expected. I did not try PR 
guests.

  This set is also required for vhost (of same endian, cross endian vhost needs a few more 
  patches which were not sent to mainline yet)

  I did a quick try on git's head (Ubuntu-3.16.0-11.16). All patches
  apply smoothly.

  Thanks,
