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.
