Merge CONFIG_HUGETLB_PAGE and CONFIG_HUGETLBFS into one new config option: CONFIG_HUGETLB. CONFIG_HUGETLB_PAGE is aliased to the value of CONFIG_HUGETLBFS, so one option can be removed without any effect. This change is pretty mechanical, but a little extra verification from arch maintainers would be very helpful. Thanks.
