Will bundle the Makefile enablement change and the needed fix in the same patch to avoid the ordering issue. Also note - I will open code the TEST_GEN_PROGS_COMMON and will skip the kvm_create_max_vcpus (& maybe few others like vm_types_test) from that in v6. > As for kvm_create_max_vcpus and hardware_disable_test, drop them from the initial > enablement so we can get the core support landed, and tackle them as separate > series post-7.4. > Sure.

Sure, Thanks a lot Sean! Let me post v6 with the suggested approach. -ritesh
