I believe you can look through the RHEL tech notes. Here they are for 6.5:

If you require barriers, you can always use the mainline kernel from elrepo. You can read about the mainline and long-term packages here:
http://elrepo.org/tiki/kernel-lt
You probably want the kernel-ml packages, but that page doesn't mention the -lt packages. Lots of CentOS admins use these kernels (including me) and are happy with them.
