#     KVM: PPC: Book3S HV: XIVE: fix rollback when kvmppc_xive_create fails
#     
#     The XIVE device structure is now allocated in kvmppc_xive_get_device()
#     and kfree'd in kvmppc_core_destroy_vm(). In case of an OPAL error when
#     allocating the XIVE VPs, the kfree() call in kvmppc_xive_*create()
#     will result in a double free and corrupt the host memory.
#     
#     Fixes: 5422e95103cf ("KVM: PPC: Book3S HV: XIVE: Replace the 'destroy' method by a 'release' method")
