During the Kconfig factor, CONFIG_MAXSMP was set for all builds instead
of just debug builds. This bumps the NR_CPUs up to 8192 which is far
more than anyone actually needs for Fedora. Stop setting CONFIG_MAXSMP
on non-debug configs and adjust NR_CPUs back to what it was before.
The existing method of managing configuration files gets unweildy.
Changing individual lines in text files gets difficult without
manual organization. Switch to a method of configuration generation
that's inspired from the method used inside Red Hat. Each configuration
option gets its own file which are then combined to form the
configuration files. This makes confirming what's actually enabled much
easier.
