CONFIG_KVM should be enough on ARM and s390 but MIPS, x86 and PPC may also need to select the specific "flavors" (for example Intel/AMD for x86). How are these used? Are they used to build a kernel, or to check that an existing kernel supports virtualization?

If the below listed configs are not harmful i would like to keep all listed configs. Because we (Linaro 's test farm) building kernels with maximum available kernel fragments for a given test case to get better coverage. > > How are these used?

"make kselftest-merge" will get configs from tools/testing/selftests/*/config and enables configs fragments and we build kernel for running kvm-unit-tests, kselftests, LTP, libhugetlbfs, ssuite, perf and v4l2-compliance. - Naresh
