    kernel - 64-bit memory & ncpus work
    
    * Create a macro and bsr function for cpu masks in preparation for
      making cpumask_t 64 bits on 64-bit builds.  cpumask_t is still
      32 bits in this commit.
    
    * Expand SMP_MAXCPUS to 31 for 64-bit builds in preparation for
      eventually expanding it to 63.
    
    * Fix an array overflow when probing ncpus on 64-bit.
    
    * Increase the boot-time kmap entries to accomodate large numbers of
      cpus.
    
    * Clean up a few places where integer overflows could occur on
      64-bit machines with large amounts of ram.
    
      For the moment we are limited to 32G.  This will change in a
      followup commit.
