Modified: i386/isa clock.c random_machdep.c
i386/i386 db_trace.c identcpu.c microtime.s
i386/include clock.h
Log:
More completely disable the use of the pentium cycle counter under SMP,
this needs a lot more work before it can be used since each cycle counter
is different on each cpu. It will need to be calibrated on each cpu,
the base offset kept, and then somehow they will need to be kept in sync.
For the time being, it's far easier to just simply ignore it and pretend
that we're a 486 for the clock code and use the 8254 counter.
