I'm very confused on the right step to use to setup a modified kernel in centOS6.
As a simple user, I've downloaded the latests sources (I'm runing an old kernel version) :
rpm -i http://vault.centos.org/6.7/updates/Source/SPackages/kernel-2.6.32-573.22.1....
in the spec file ~/rpmbuild/SPECS/kernel.spec I've set: %define buildid .numa
Now I want to set *CONFIG_NUMA_EMU=y* before runing: rpmbuild -bb --without xen --without debug --without debuginfo --target=x86_64 ./SPECS/kernel.spec
But where shoud I set this CONFIG_NUMA_EMU option ? I've tested several config files where this options was specified (using grep as a last solution) but each build reset my choice and it is not available in the final kernel.
And google is a little bit confusing for me with many and many diverging informations.
Thank to kernel gourous for their advices.
