    sys/sparc64/sparc64  tick.c 
  Log:
  Merge from RELENG_5: cpufunc.h 1.18.2.1; tick.c 1.14.4.2
  
  - Add a workaround for a bug in BlackBird CPUs (said to be part of the
    SpitFire erratum #54) which can cause writes to the TICK_CMPR register
    to fail. This seems to fix the dying clocks problem reported by jhb@
    and kris at .
  - In tick_init() just use tick_stop() for stopping the tick interrupts
    until a proper handler is set up later. This also stops the system
    tick interrupt on USIII systems earlier.
  - Some minor changes, e.g. use FBSDID, remove unused headers, etc.
