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' ...

mm/vma: define a default value for VM_DATA_DEFAULT_FLAGS

2020-04-10T22:36:21Z

There are many platforms with exact same value for VM_DATA_DEFAULT_FLAGS This creates a default value for VM_DATA_DEFAULT_FLAGS in line with the existing VM_STACK_DEFAULT_FLAGS. While here, also define some more macros with standard VMA access flag combinations that are used frequently across many platforms. Apart from simplification, this reduces code duplication as well.

sh: use __builtin_constant_p() directly instead of IS_IMMEDIATE()

2020-04-08T15:01:58Z

__builtin_constant_p(nr) is used everywhere now. It does not make much sense to define IS_IMMEDIATE() as its alias. Signed-off-by: Masahiro Yamada

asm-generic: make more kernel-space headers mandatory

2020-04-02T16:35:25Z

Change a header to mandatory-y if both of the following are met: [1] At least one architecture (except um) specifies it as generic-y in arch/*/include/asm/Kbuild [2] Every architecture (except um) either has its own implementation (arch/*/include/asm/*.h) or specifies it as generic-y in arch/*/include/asm/Kbuild This commit was generated by the following shell script. ----------------------------------->8----------------------------------- arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d') tmpfile=$(mktemp) grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile find arch -path 'arch/*/include/asm/Kbuild' | xargs sed -n 's/^generic-y += $.*$/\1/p' | sort -u | while read header do mandatory=yes for arch in $arches do if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild && ! [ -f arch/$arch/include/asm/$header ]; then mandatory=no break fi done if [ "$mandatory" = yes ]; then echo "mandatory-y += $header" >> $tmpfile for arch in $arches do sed -i "/generic-y += $header/d" arch/$arch/include/asm/Kbuild done fi done sed -i '/^mandatory-y +=/d' include/asm-generic/Kbuild LANG=C sort $tmpfile >> include/asm-generic/Kbuild ----------------------------------->8----------------------------------- One obvious benefit is the diff stat: 25 files changed, 52 insertions(+), 557 deletions(-) It is tedious to list generic-y for each arch that needs it. So, mandatory-y works like a fallback default (by just wrapping asm-generic one) when arch does not have a specific header implementation. See the following commits: def3f7cefe4e81c296090e1722a76551142c227c a1b39bae16a62ce4aae02d958224f19316d98b24 It is tedious to convert headers one by one, so I processed by a shell script.

sh: no need of access_ok() in arch_futex_atomic_op_inuser()

everything it uses is doing access_ok() already Signed-off-by: Al Viro

futex: arch_futex_atomic_op_inuser() calling conventions change

2020-03-28T03:58:51Z

Move access_ok() in and pagefault_enable()/pagefault_disable() out. Mechanical conversion only - some instances don't really need a separate access_ok() at all (e.g. the ones only using get_user()/put_user(), or architectures where access_ok() is always true); we'll deal with that in followups.
