Thanks for your providing. But I'm saying that since HUGETLBFS depends on (SYSFS or SYSCTL), how CONFIG_PPC_8xx succeeds to select it while
SYSFS and SYSCTL are disabled? I'm not really familiar with Kconfig but I assume Kconfig will confirm that the dependencies are satisfied
before HUGETLBFS is enabled. Or am I miss something?

Thank.
