The problem is that lib/lib.a is listed _before_ arch/arm/lib/lib.a in the link argument list so the architecture specific lib functions are not picked up in priority. To work around this the following patch is needed: --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -142,7 +142,7 @@ drivers-$(CONFIG_OPROFILE) += arch/ drivers-$(CONFIG_ARCH_CLPS7500) += drivers/acorn/char/ drivers-$(CONFIG_ARCH_L7200) += drivers/acorn/char/ -libs-y += arch/arm/lib/ +libs-y := arch/arm/lib/ $(libs-y) # Default target when executing plain make ifeq ($(CONFIG_XIP_KERNEL),y) However I was wondering if there should be a better and generic way to fix that.
