#     powerpc/64s: Prevent fallthrough to hash TLB flush when using radix
#     
#     In the fix reconnecting hash__tlb_flush() to tlb_flush() the
#     void return on radix__tlb_flush() was not restored and subsequently
#     falls through to the restored hash__tlb_flush().
#     
#     Guard hash__tlb_flush() under an else to prevent this.
#     
#     Fixes: 1665c027afb2 ("powerpc/64s: Reconnect tlb_flush() to hash__tlb_flush()")
