Messages in this thread Patch in this message | | | From | Christophe Leroy <> | Subject | [PATCH] powerpc/64s: Only set HAVE_ARCH_UNMAPPED_AREA when CONFIG_PPC_64S_HASH_MMU is set | Date | Tue, 24 May 2022 07:42:05 +0200 |
| |
When CONFIG_PPC_64S_HASH_MMU is not set, slice.c is not built and arch_get_unmapped_area() and arch_get_unmapped_area_topdown() are not provided because RADIX uses the generic ones.
Therefore, neither set HAVE_ARCH_UNMAPPED_AREA nor HAVE_ARCH_UNMAPPED_AREA_TOPDOWN.
