Sure, makes sense, will send it for ppc64_defconfig instead. 
Inaddition, Have few more symbols to be enabled for cgroups,
memhotplug,numa balancing.
I guess these symbols can also go to ppc64_defconfig itself?.

i.e,

CONFIG_CGROUP_SCHED=y
CONFIG_MEMCG=y
CONFIG_CGROUP_SCHED=y
CONFIG_CGROUP_FREEZER=y
CONFIG_CGROUP_DEVICE=y
CONFIG_CGROUP_CPUACCT=y
CONFIG_CGROUP_PERF=y
CONFIG_MEMORY_HOTPLUG=y
CONFIG_MEMORY_HOTREMOVE=y
CONFIG_NUMA_BALANCING=y

Thanks!
