    sys/i386/isa         clock.c 
  Log:
  This commit gives support for the Rise mP6 CPU. It has two changes:
  	1. Rise is recognized in identdcpu.c.
  	2. The TSC is not written to. A workaround for the CPU bug is being
  	   applied to clock.c (the bug being that the mP6 has TSC enabled
  	   in its CPUID-capabilities, but it only supports reading it. If we
  	   try to write to it (MSR 16), a GPF occurs.) The new behavior is that
  	   FreeBSD will _not_ zero the TSC. Instead, we do a bit of 64-bit
  	   arithmetic.
