Merge tag 'kbuild-v5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada: - raise minimum supported binutils version to 2.23 - remove old CONFIG_AS_* macros that we know binutils >= 2.23 supports - move remaining CONFIG_AS_* tests to Kconfig from Makefile - enable -Wtautological-compare warnings to catch more issues - do not support GCC plugins for GCC <= 4.7 - fix various breakages of 'make xconfig' - include the linker version used for linking the kernel into LINUX_COMPILER, which is used for the banner, and also exposed to /proc/version - link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y, which allows us to remove the lib-ksyms.o workaround, and to solve the last known issue of the LLVM linker - add dummy tools in scripts/dummy-tools/ to enable all compiler tests in Kconfig, which will be useful for distro maintainers - support the single switch, LLVM=1 to use Clang and all LLVM utilities instead of GCC and Binutils. - support LLVM_IAS=1 to enable the integrated assembler, which is still experimental * tag 'kbuild-v5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (36 commits) kbuild: fix comment about missing include guard detection kbuild: support LLVM=1 to switch the default tools to Clang/LLVM kbuild: replace AS=clang with LLVM_IAS=1 kbuild: add dummy toolchains to enable all cc-option etc. in Kconfig kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y MIPS: fw: arc: add __weak to prom_meminit and prom_free_prom_memory kbuild: remove -I$(srctree)/tools/include from scripts/Makefile kbuild: do not pass $(KBUILD_CFLAGS) to scripts/mkcompile_h Documentation/llvm: fix the name of llvm-size kbuild: mkcompile_h: Include $LD version in /proc/version kconfig: qconf: Fix a few alignment issues kconfig: qconf: remove some old bogus TODOs kconfig: qconf: fix support for the split view mode kconfig: qconf: fix the content of the main widget kconfig: qconf: Change title for the item window kconfig: qconf: clean deprecated warnings gcc-plugins: drop support for GCC <= 4.7 kbuild: Enable -Wtautological-compare x86: update AS_* macros to binutils >=2.23, supporting ADX and AVX2 crypto: x86 - clean up poly1305-x86_64-cryptogams.S by 'make clean' ...
