#     KVM: PPC: Fix kvm_arch_vcpu_ioctl vcpu_load leak
#     
#     vcpu_put is not called if the user copy fails. This can result in preempt
#     notifier corruption and crashes, among other issues.
#     
#     Fixes: b3cebfe8c1ca ("KVM: PPC: Move vcpu_load/vcpu_put down to each ioctl case in kvm_arch_vcpu_ioctl")
