From 54501ac150fed82b256e6a9bd4e2201bc3b21b22 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 10 Jul 2018 17:16:27 +0200 Subject: [PATCH] arm64: make flatmem depend on !NUMA Building without NUMA but with FLATMEM results in a link error because mem_map[] is not available: aarch64-linux-ld -EB -maarch64elfb --no-undefined -X -pie -shared -Bsymbolic --no-apply-dynamic-relocs --build-id -o .tmp_vmlinux1 -T ./arch/arm64/kernel/vmlinux.lds --whole-archive built-in.a --no-whole-archive --start-group arch/arm64/lib/lib.a lib/lib.a --end-group init/do_mounts.o: In function `mount_block_root': do_mounts.c:(.init.text+0x1e8): undefined reference to `mem_map' arch/arm64/kernel/vdso.o: In function `vdso_init': vdso.c:(.init.text+0xb4): undefined reference to `mem_map' This uses the same trick as the other architectures, making flatmem depend on !NUMA to avoid the broken configuration.
