If anyone has any objections, please let me know. ------------------ From: Nathan Chancellor commit cff6e7f50bd315e5b39c4e46c704ac587ceb965f upstream. A future change will move CLANG_FLAGS from KBUILD_{A,C}FLAGS to KBUILD_CPPFLAGS so that '--target' is available while preprocessing. When that occurs, the following errors appear multiple times when building ARCH=powerpc powernv_defconfig: ld.lld: error: vmlinux.a(arch/powerpc/kernel/head_64.o):(.text+0x12d4): relocation R_PPC64_ADDR16_HI out of range: -4611686018409717520 is not in [-2147483648, 2147483647]; references '__start___soft_mask_table' ld.lld: error: vmlinux.a(arch/powerpc/kernel/head_64.o):(.text+0x12e8): relocation R_PPC64_ADDR16_HI out of range: -4611686018409717392 is not in [-2147483648, 2147483647]; references '__stop___soft_mask_table' Diffing the .o.cmd files reveals that -DHAVE_AS_ATHIGH=1 is not present anymore, because as-instr only uses KBUILD_AFLAGS, which will no longer contain '--target'. Mirror Kconfig's as-instr and add CLANG_FLAGS explicitly to the invocation to ensure the target information is always present.
