s390/mm: silence compiler warning when compiling without CONFIG_PGSTE
[ Upstream commit 81a8f2beb32a5951ecf04385301f50879abc092b ]
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.
