afacit, CONFIG_HUGETLBFS must be enabled if CONFIG_HUGETLB_PAGE=y, and
thp-config_transparent_hugepage.patch broke that, by permitting
CONFIG_HUGETLBFS=n, CONFIG_HUGETLB_PAGE=y,
CONFIG_TRANSPARENT_HUGEPAGE=y.
I suppose CONFIG_TRANSPARENT_HUGEPAGE could select CONFIG_HUGETLBFS,
but is there a nicer way?
There's lots of stuff in hugetlb.h which is clearly related to
hugetlbfs, but is enabled by CONFIG_HUGETLB_PAGE, so those things seem
to be pretty joined at the hip nowadays.
