pgtable_pmd_page_ctor() must be used on user pmd. For kernel pmd, it's okay to use pgtable_page_ctor() instead only because kernel doesn't have thp.

See HAVE_ARCH_HUGE_VMAP which is supported by arm64. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
