I collected more Reviewed-by and Acked-by, then pushed this series to git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git kbuild-asinstr It will show up in -next soon.

Dropped Nick's Reviewed-by.
This series of cleanups was prompted by Linus: https://lkml.org/lkml/2020/3/12/726 First, this series drop always-on CONFIG_AS_* options. Some of those options were introduced in old days. For example, the check for CONFIG_AS_CFI dates back to 2006. We raise the minimal tool versions from time to time. Currently, we require binutils 2.21 (and we even plan to bump it to 2.23). After cleaning away the old checks, as-instr calls are moved to Kconfig from Makefiles, then more Kconfig / Makefile code is cleaned up. I folded all relevanet patches into this series, as suggested by Jason A. Donenfeld. The update for v2 is quite small. I just swapped the patch order of patch 8 and 11 instead of moving comments around files, which was addressed by Nick Desaulniers. Borislav Petkov (1): Documentation/changes: Raise minimum supported binutils version to 2.23 Jason A. Donenfeld (4): x86: probe assembler capabilities via kconfig instead of makefile crypto: x86 - rework configuration based on Kconfig crypto: curve25519 - do not pollute dispatcher based on assembler x86: update AS_* macros to binutils >=2.23, supporting ADX and AVX2 Masahiro Yamada (11): lib/raid6/test: fix build on distros whose /bin/sh is not bash x86: remove unneeded defined(__ASSEMBLY__) check from asm/dwarf2.h x86: remove always-defined CONFIG_AS_CFI x86: remove unneeded (CONFIG_AS_)CFI_SIGNAL_FRAME x86: remove always-defined CONFIG_AS_CFI_SECTIONS x86: remove always-defined CONFIG_AS_SSSE3 x86: remove always-defined CONFIG_AS_AVX x86: replace arch macros from compiler with CONFIG_X86_{32,64} drm/i915: remove always-defined CONFIG_AS_MOVNTDQA x86: add comments about the binutils version to support code in as-instr crypto: x86 - clean up poly1305-x86_64-cryptogams.S by 'make clean' Documentation/process/changes.rst | 4 +- arch/x86/Kconfig | 2 + arch/x86/Kconfig.assembler | 17 ++ arch/x86/Makefile | 22 --- arch/x86/crypto/Makefile | 162 +++++++----------- arch/x86/crypto/aesni-intel_avx-x86_64.S | 6 - arch/x86/crypto/aesni-intel_glue.c | 21 +-- arch/x86/crypto/blake2s-core.S | 2 - arch/x86/crypto/chacha_glue.c | 6 +- arch/x86/crypto/poly1305-x86_64-cryptogams.pl | 16 -- arch/x86/crypto/poly1305_glue.c | 11 +- arch/x86/crypto/sha1_ssse3_asm.S | 4 - arch/x86/crypto/sha1_ssse3_glue.c | 13 -- arch/x86/crypto/sha256-avx-asm.S | 3 - arch/x86/crypto/sha256-avx2-asm.S | 3 - arch/x86/crypto/sha256_ssse3_glue.c | 12 -- arch/x86/crypto/sha512-avx-asm.S | 2 - arch/x86/crypto/sha512-avx2-asm.S | 3 - arch/x86/crypto/sha512_ssse3_glue.c | 10 -- arch/x86/include/asm/dwarf2.h | 44 ----- arch/x86/include/asm/xor_avx.h | 9 - drivers/gpu/drm/i915/Makefile | 3 - drivers/gpu/drm/i915/i915_memcpy.c | 5 - include/crypto/curve25519.h | 6 +- kernel/signal.c | 2 +- lib/raid6/algos.c | 12 +- lib/raid6/avx2.c | 4 - lib/raid6/recov_avx2.c | 6 - lib/raid6/recov_ssse3.c | 6 - lib/raid6/test/Makefile | 9 +- 30 files changed, 101 insertions(+), 324 deletions(-) create mode 100644 arch/x86/Kconfig.assembler
