If anyone has any objections, please let me know. ------------------ From: Heiko Carstens commit c985cb37f1b39c2c8035af741a2a0b79f1fbaca7 upstream. Because of a change in the s390 arch backend of binutils (commit 23ecd77 "Pick the default arch depending on the target size" in binutils repo) 31 bit builds will fail since the linker would now try to create 64 bit binary output. Fix this by setting OUTPUT_ARCH to s390:31-bit instead of s390. Thanks to Andreas Krebbel for figuring out the issue. Fixes this build error: LD init/built-in.o s390x-4.7.2-ld: s390:31-bit architecture of input file `arch/s390/kernel/head.o' is incompatible with s390:64-bit output Cc: Andreas Krebbel Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky Signed-off-by: Herton Ronaldo Krzesinski --- arch/s390/boot/compressed/vmlinux.lds.S | 2 +- arch/s390/kernel/vmlinux.lds.S | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/s390/boot/compressed/vmlinux.lds.S b/arch/s390/boot/compressed/vmlinux.lds.S index d80f79d..8e1fb82 100644 --- a/arch/s390/boot/compressed/vmlinux.lds.S +++ b/arch/s390/boot/compressed/vmlinux.lds.S @@ -5,7 +5,7 @@ OUTPUT_FORMAT("elf64-s390", "elf64-s390", "elf64-s390") OUTPUT_ARCH(s390:64-bit) #else OUTPUT_FORMAT("elf32-s390", "elf32-s390", "elf32-s390") -OUTPUT_ARCH(s390) +OUTPUT_ARCH(s390:31-bit) #endif ENTRY(startup) diff --git a/arch/s390/kernel/vmlinux.lds.S b/arch/s390/kernel/vmlinux.lds.S index 21109c6..1343d7c 100644 --- a/arch/s390/kernel/vmlinux.lds.S +++ b/arch/s390/kernel/vmlinux.lds.S @@ -8,7 +8,7 @@ #ifndef CONFIG_64BIT OUTPUT_FORMAT("elf32-s390", "elf32-s390", "elf32-s390") -OUTPUT_ARCH(s390) +OUTPUT_ARCH(s390:31-bit) ENTRY(startup) jiffies = jiffies_64 + 4; #else -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
