Description of problem: Per this feature request ( IBM Bug ID : 96091, Redhat Bug ID : 989577) "CGROUP_HUGETLB" kernel option was already enabled in kernel version "kernel-3.10.0-12.el7". Check below comment:
The kernel version of F20 is greater than above kernel version & it is expected to have this kernel option enabled. But this kernel option is still "not set" in F20-Beta kernel.
[root@juno-ioxc1-lp1 ~]# uname -a
Linux juno-ioxc1-lp1.xxxx.ibm.com 3.11.6-301.fc20.ppc64p7 #1 SMP Mon Oct 21 18:49:17 MST 2013 ppc64 ppc64 ppc64 GNU/Linux
[root@juno-ioxc1-lp1 ~]# cat /boot/config-3.11.6-301.fc20.ppc64p7 | grep CONFIG_CGROUP_HUGETLB
# CONFIG_CGROUP_HUGETLB is not set
How reproducible: Always.
Version-Release number of selected component (if applicable):
Fedora 20 Beta - 3.11.6-301.fc20.ppc64p7
Steps to Reproduce:
1) Check availability of above mentioned kernel option.
Actual results: Kernel option is not set
Expected results: Kernel option should be set
Additional info: Let me know if you need any.
Fedora doesn't follow and isn't aware of RHEL feature requests. Fedora also has a large variety of config settings that differ from RHEL kernels. If you want something set in Fedora, you need to open a bug against Fedora and request it. Please communicate this to your teams for future reference.
We'll treat this bug as such a request for now.
I've enabled this on F20 and rawhide for ppc64/ppc64p7 and x86_64. It will be in the next build of each.
kernel-3.11.9-300.fc20 has been submitted as an update for Fedora 20.

Update it with:

I checked by updating to kernel "3.11.9-300.fc20.ppc64p7". kernel option "CGROUP_HUGETLB" is now enabled.
The correct & expected output is below:-
[root@transam2s-lp1 ~]# cat /boot/config-3.11.9-300.fc20.ppc64p7 | grep CONFIG_CGROUP_HUGETLB
