There are three flavors of GENERIC from the MP point of view:

  GENERIC: runs fine on dual-processor machines, but only uses 1
  processor

  GENERIC.MP: uses MPBIOS to find/start additional processors.
  Typically useful for pretty old machines

  GENERIC.MPACPI: uses ACPI for additional processors.  Typically useful
  for moderate to new machines


If you have a machine that can take 2 processors but only has 1, you
might as well use just GENERIC.
