From 156152f84e57bff4d9b5d70be6f3f16116bf6fb1 Mon Sep 17 00:00:00 2001 From: Gerald Schaefer Date: Thu, 25 Oct 2012 17:24:12 +0200 Subject: [PATCH] s390/mm: use pmd_large() instead of pmd_huge() Without CONFIG_HUGETLB_PAGE, pmd_huge() will always return 0. So pmd_large() should be used instead in places where both transparent huge pages and hugetlbfs pages can occur.
