    sys/sparc64/sparc64  tick.c 
  Log:
  MFC: 1.15
  
  UltraSparc II[e,i] based systems come up with the tick interrupt
  enabled and a handler that resets the tick counter, causing DELAY()
  to not work properly when used early in boot.
  Disable the tick interrupt in tick_init(), which is called early in
  sparc64_init(), until the interrupt is enabled again in tick_start(),
  called by cpu_initclocks(), with our own handler. This fixes the hang
  during probing Sun keyboards on AXi boards and Ultra 10, with other
  machines like Ultra 5 probably being affected but not tested.
