Ignore the double UD2 which is emitted in BUG() when # CONFIG_UBSAN_TRAP is enabled. # # - Support clang non-section symbols in objtool ORC dump # # - Fix switch table detection in .text.unlikely # # - Make the BP scratch register warning more robust. # # x86: # # - Increase microcode maximum patch size for AMD to cope with new CPUs # which have a larger patch size. # # - Fix a crash in the resource control filesystem when the removal of # the default resource group is attempted. # # - Preserve Code and Data Prioritization enabled state accross CPU # hotplug. # # - Update split lock cpu matching to use the new X86_MATCH macros. # # - Change the split lock enumeration as Intel finaly decided that the # IA32_CORE_CAPABILITIES bits are not architectural contrary to what # the SDM claims. !@#%$^! # # - Add Tremont CPU models to the split lock detection cpu match. # # - Add a missing static attribute to make sparse happy" # # * tag 'x86-urgent-2020-04-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/split_lock: Add Tremont family CPU models # x86/split_lock: Bits in IA32_CORE_CAPABILITIES are not architectural # x86/resctrl: Preserve CDP enable over CPU hotplug # x86/resctrl: Fix invalid attempt at removing the default resource group # x86/split_lock: Update to use X86_MATCH_INTEL_FAM6_MODEL() # x86/umip: Make umip_insns static # x86/microcode/AMD: Increase microcode PATCH_MAX_SIZE # objtool: Make BP scratch register warning more robust # objtool: Fix switch table detection in .text.unlikely # objtool: Support Clang non-section symbols in ORC generation # objtool: Support Clang non-section symbols in ORC dump # objtool: Fix CONFIG_UBSAN_TRAP unreachable warnings # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 0fe5f9ca223573167c4c4156903d751d2c8e160e # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- randconfig KCONFIG_SEED=0xB3DA5B88 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig .config:4256:warning: override: reassigning to symbol STANDALONE .config:4260:warning: override: reassigning to symbol PPC64 .config:4261:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:4262:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:4268:warning: override: reassigning to symbol UBSAN WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [y]: -
