kvm_arch_vcpu_free() is called in 2 code paths:

1) kvm_vm_ioctl()
       kvm_vm_ioctl_create_vcpu()
           kvm_arch_vcpu_destroy()
               kvm_arch_vcpu_free()
2) kvm_put_kvm()
       kvm_destroy_vm()
           kvm_arch_destroy_vm()
               kvm_mips_free_vcpus()
                   kvm_arch_vcpu_free()

Neither of the paths handles VCPU free. We need to do it in
kvm_arch_vcpu_free() corresponding to the memory allocation in
kvm_arch_vcpu_create().

Maybe worth adding "Cc: stable@xxxxxxxxxxxxxxx" and moving this to the
beginning of the patchset to avoid conflicts.

I've queued this for 3.16. It applies cleanly apart for the filename change.
