From 3376d753bc49653c288b54bac05fe5a0205231ad Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 3 Sep 2008 13:12:05 +1000 Subject: [PATCH] powerpc: Fix build error with 64K pages and !hugetlbfs HAVE_ARCH_UNMAPPED_AREA and HAVE_ARCH_UNMAPPED_AREA_TOPDOWN must be defined whenever CONFIG_PPC_MM_SLICES is enabled, not just when CONFIG_HUGETLB_PAGE is. They used to be always defined together but this is no longer the case since b83f707c922bb78ae1b3821a37e03282ef1b483a ("powerpc: Only demote individual slices rather than whole process").
