From 81a8f2beb32a5951ecf04385301f50879abc092b Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Sun, 7 Apr 2019 14:55:09 +0200 Subject: [PATCH] s390/mm: silence compiler warning when compiling without CONFIG_PGSTE MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If CONFIG_PGSTE is not set (e.g. when compiling without KVM), GCC complains: CC arch/s390/mm/pgtable.o arch/s390/mm/pgtable.c:413:15: warning: ‘pmd_alloc_map’ defined but not used [-Wunused-function] static pmd_t *pmd_alloc_map(struct mm_struct *mm, unsigned long addr) ^~~~~~~~~~~~~ Wrap the function with "#ifdef CONFIG_PGSTE" to silence the warning.
