Hi George,
  I think you're looking for CONFIG_SMP and CONFIG_NR_CPUS.  There are some
details here: http://cateee.net/lkddb/web-lkddb/NR_CPUS.html.

  One thing to note is that sometimes the Linux kconfigs set range
restrictions on the number of CPU cores.  Sometimes these limitations are
based on hardware restrictions, such as the design of interrupt devices,
and other times they are soft limits that can be fudged for running in gem5
(I don't recall the details off-hand, but it involves modifying a range
parameter in kconfigs - check out:
https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt).

  Hope this helps,
  Joel
