The vector number is pushed into the # errorcode slot on the stack which is then lifted into an argument # and set to -1 because that's regs->orig_ax which is used in quite # some places to check whether the entry came from a syscall. # # But it was overlooked that orig_ax is used in the affinity cleanup # code to validate whether the interrupt has arrived on the new # target. It turned out that this vector check is pointless because # interrupts are never moved from one vector to another on the same # CPU. That check is a historical leftover from the time where x86 # supported multi-CPU affinities, but not longer needed with the now # strict single CPU affinity. Famous last words ... # # - Add a missing check for an empty cpumask into the matrix allocator. # # The affinity change added a warning to catch the case where an # interrupt is moved on the same CPU to a different vector. This # triggers because a condition with an empty cpumask returns an # assignment from the allocator as the allocator uses for_each_cpu() # without checking the cpumask for being empty. The historical # inconsistent for_each_cpu() behaviour of ignoring the cpumask and # unconditionally claiming that CPU0 is in the mask struck again. # Sigh. # # plus a new entry into the MAINTAINER file for the HPE/UV platform" # # * tag 'x86-urgent-2020-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # genirq/matrix: Deal with the sillyness of for_each_cpu() on UP # x86/irq: Unbreak interrupt affinity setting # x86/hotplug: Silence APIC only after all interrupts are migrated # MAINTAINERS: Add entry for HPE Superdome Flex (UV) maintainers # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 dcc5c6f013d841e9ae74d527d312d512dfc2e2f0 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x4D40138 # 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 24 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:3385:warning: override: reassigning to symbol CPU_BIG_ENDIAN .config:3385:warning: override: CPU_BIG_ENDIAN changes choice state .config:3387:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:3389:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:3392:warning: override: reassigning to symbol LD_HEAD_STUB_CATCH .config:3394:warning: override: reassigning to symbol UBSAN # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/watchdog.c:47:23: warning: 'watchdog_allowed_mask' defined but not used [-Wunused-variable] 47 | static struct cpumask watchdog_allowed_mask __read_mostly; | ^~~~~~~~~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld: arch/powerpc/platforms/pseries/lpar.o:(.toc+0x0): undefined reference to `mmu_pid_bits' make[1]: *** [/kisskb/src/Makefile:1166: vmlinux] Error 1 make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 24 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc9 # Build took: 0:03:44.987524
