AFAIK I need only set CONFIG_SMP and I will enable all the cores on my
processor. (In older days, I seem to remember specifying the number
somewhere in the kernel configuration file, but I couldn't find anything
like that on 3.10.10).
If you build for SMP, you probably do not want
CONFIG_BROKEN_ON_SMP. As its name suggests, it is for things which
do not work correctly on SMP. As of 3.15.0 the drivers which might
be relevant are mentioned in the Kconfig files in :
drivers/net/hamradio/
drivers/i2c/busses/
drivers/isdn/i4l/
init/
There are also references in the powerpc, sh, and mips
architectures.

Now <cat /proc/cpuinfo> shows me four processors AND I get four cute
penguins when I boot. Plus I found a brand new,stable--not beta--
Catalyst Driver for my HD Radeon graphics. I just don't understand why
this wouldn't boot six months ago. Any way thanks to William, Ken and
Bruce.
