Indeed, keeping the KVM option as tristate helps showing the right
suboptions, similar to what Andrea did in patch 2.  However, this patch
already breaks the CONFIG_KVM_INTEL=y && CONFIG_KVM_AMD=y case I think,
so it should be squashed with "KVM: monolithic: x86: disable linking vmx
and svm at the same time into the kernel".

The patch doesn't change the fact that enabling KVM on its own does
nothing, so the help text can be updated independently (patch welcome :)).

Thanks,
