Building a kernel with CPU_BIG_ENDIAN fails if there are stale objects from a !CPU_BIG_ENDIAN build. Due to a missing FORCE prerequisite on an if_changed rule in the VDSO Makefile, we attempt to link a stale LE object into the new BE kernel. According to Documentation/kbuild/makefiles.txt, FORCE is required for if_changed rules and forgetting it is a common mistake, so fix it by 'Forcing' the build of vdso. This patch fixes build errors like these: arch/arm64/kernel/vdso/note.o: compiled for a little endian system and target is big endian failed to merge target specific data of file arch/arm64/kernel/vdso/note.o arch/arm64/kernel/vdso/sigreturn.o: compiled for a little endian system and target is big endian failed to merge target specific data of file arch/arm64/kernel/vdso/sigreturn.o Tested-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Arun Chandran <achandran@mvista.com> Signed-off-by: Will Deacon <will.deacon@arm.com> |
