Log:
MFC: cpufunc.h 1.19, 1.20; tick.c 1.16 (partial)
- 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@.
- 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.
