2021-02-10x86/build: Disable CET instrumentation in the kernelJosh Poimboeuf
commit 20bf2b378729c4a0366a53e2018a0b70ace94bcd upstream. With retpolines disabled, some configurations of GCC, and specifically the GCC versions 9 and 10 in Ubuntu will add Intel CET instrumentation to the kernel by default. That breaks certain tracing scenarios by adding a superfluous ENDBR64 instruction before the fentry call, for functions which can be called indirectly. CET instrumentation isn't currently necessary in the kernel, as CET is only supported in user space. Disable it unconditionally and move it into the x86's Makefile as CET/CFI... enablement should be a per-arch decision anyway.

2020-12-30Kbuild: do not emit debug info for assembly with LLVM_IAS=1Nick Desaulniers
commit b8a9092330da2030496ff357272f342eb970d51b upstream. Clang's integrated assembler produces the warning for assembly files: warning: DWARF2 only supports one section per compilation unit If -Wa,-gdwarf-* is unspecified, then debug info is not emitted for assembly sources (it is still emitted for C sources). This will be re-enabled for newer DWARF versions in a follow up patch. Enables defconfig+CONFIG_DEBUG_INFO to build cleanly with LLVM=1 LLVM_IAS=1 for x86_64 and arm64.

2020-09-26kbuild: support LLVM=1 to switch the default tools to Clang/LLVMMasahiro Yamada
commit a0d1c951ef08ed24f35129267e3595d86f57f5d3 upstream. As Documentation/kbuild/llvm.rst implies, building the kernel with a full set of LLVM tools gets very verbose and unwieldy. Provide a single switch LLVM=1 to use Clang and LLVM tools instead of GCC and Binutils. You can pass it from the command line or as an environment variable. Please note LLVM=1 does not turn on the integrated assembler. You need to pass LLVM_IAS=1 to use it. When the upstream kernel is ready for the integrated assembler, I think we can make it default. We discussed what we need, and we agreed to go with a simple boolean flag that switches both target and host tools: https://lkml.org/lkml/2020/3/28/494 https://lkml.org/lkml/2020/4/3/43 Some items discussed, but not adopted: - LLVM_DIR When multiple versions of LLVM are installed, I just thought supporting LLVM_DIR=/path/to/my/llvm/bin/ might be useful. CC = $(LLVM_DIR)clang LD = $(LLVM_DIR)ld.lld ... However, we can handle this by modifying PATH. So, we decided to not do this. - LLVM_SUFFIX Some distributions (e.g. Debian) package specific versions of LLVM with naming conventions that use the version as a suffix. CC = clang$(LLVM_SUFFIX) LD = ld.lld(LLVM_SUFFIX) ... will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc., but the suffixed versions in /usr/bin/ are symlinks to binaries in /usr/lib/llvm-#/bin/, so this can also be handled by PATH.

2020-09-26kbuild: replace AS=clang with LLVM_IAS=1Masahiro Yamada
commit 7e20e47c70f810d678d02941fa3c671209c4ca97 upstream. The 'AS' variable is unused for building the kernel. Only the remaining usage is to turn on the integrated assembler. A boolean flag is a better fit for this purpose. AS=clang was added for experts. So, I replaced it with LLVM_IAS=1, breaking the backward compatibility.

2020-09-26kbuild: remove AS variableMasahiro Yamada
commit aa824e0c962b532d5073cbb41b2efcd6f5e72bae upstream. As commit 5ef872636ca7 ("kbuild: get rid of misleading $(AS) from documents") noted, we rarely use $(AS) directly in the kernel build. Now that the only/last user of $(AS) in drivers/net/wan/Makefile was converted to $(CC), $(AS) is no longer used in the build process. You can still pass in AS=clang, which is just a switch to turn on the LLVM integrated assembler.

2020-09-26x86/boot: kbuild: allow readelf executable to be specifiedDmitry Golovin
commit eefb8c124fd969e9a174ff2bedff86aa305a7438 upstream. Introduce a new READELF variable to top-level Makefile, so the name of readelf binary can be specified. Before this change the name of the binary was hardcoded to "$(CROSS_COMPILE)readelf" which might not be present for every toolchain. This allows to build with LLVM Object Reader by using make parameter READELF=llvm-readelf.

2020-09-26kbuild: add OBJSIZE variable for the size toolVasily Gorbik
commit 7bac98707f65b93bf994ef4e99b1eb9e7dbb9c32 upstream. Define and export OBJSIZE variable for "size" tool from binutils to be used in architecture specific Makefiles (naming the variable just "SIZE" would be too risky). In particular this tool is useful to perform checks that early boot code is not using bss section (which might have not been zeroed yet or intersects with initrd or other files boot loader might have put right after the linux kernel).
