To work around that, we can force the use of the out-of-line version for configurations that build a OABI kernel. Without this patch, building netx_defconfig results in: net/core/pktgen.c: In function 'pktgen_if_show': net/core/pktgen.c:682:2775: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' net/core/pktgen.c:682:3153: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' net/core/pktgen.c:682:2775: error: 'asm' operand has impossible constraints net/core/pktgen.c:682:3153: error: 'asm' operand has impossible constraints Signed-off-by: Arnd Bergmann Signed-off-by: Russell King --- diff --git a/arch/arm/include/asm/div64.h b/arch/arm/include/asm/div64.h index fe92ccf1d0b0..191ada6e4d2d 100644 --- a/arch/arm/include/asm/div64.h +++ b/arch/arm/include/asm/div64.h @@ -46,7 +46,7 @@ __rem; \ }) -#if __GNUC__ < 4 +#if __GNUC__ < 4 || !defined(CONFIG_AEABI) /* * gcc versions earlier than 4.0 are simply too problematic for the
