This is caused by an ordering issue # introduced in the recent changes which skip PIT initialization when # the TSC and APIC frequencies are already known. # # - Handle malformed SRAT tables during early ACPI parsing which caused # an infinite loop anda boot hang. # # - Fix a long standing race in the affinity setting code which affects # PCI devices with non-maskable MSI interrupts. The problem is caused # by the non-atomic writes of the MSI address (destination APIC id) # and data (vector) fields which the device uses to construct the MSI # message. The non-atomic writes are mandated by PCI. # # If both fields change and the device raises an interrupt after # writing address and before writing data, then the MSI block # constructs a inconsistent message which causes interrupts to be # lost and subsequent malfunction of the device. # # The fix is to redirect the interrupt to the new vector on the # current CPU first and then switch it over to the new target CPU. # This allows to observe an eventually raised interrupt in the # transitional stage (old CPU, new vector) to be observed in the APIC # IRR and retriggered on the new target CPU and the new vector. # # The potential spurious interrupts caused by this are harmless and # can in the worst case expose a buggy driver (all handlers have to # be able to deal with spurious interrupts as they can and do happen # for various reasons). # # - Add the missing suspend/resume mechanism for the HYPERV hypercall # page which prevents resume hibernation on HYPERV guests. This # change got lost before the merge window. # # - Mask the IOAPIC before disabling the local APIC to prevent # potentially stale IOAPIC remote IRR bits which cause stale # interrupt lines after resume" # # * tag 'x86-urgent-2020-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # x86/apic: Mask IOAPIC entries when disabling the local APIC # x86/hyperv: Suspend/resume the hypercall page for hibernation # x86/apic/msi: Plug non-maskable MSI affinity race # x86/boot: Handle malformed SRAT tables during early ACPI parsing # x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 1a2a76c2685a29e46d7b37e752ccea7b15aa8e24 # < make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # yes \n | make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/signal.c: In function 'sig_handler_common': /kisskb/src/arch/um/os-Linux/signal.c:51:1: warning: the frame size of 2976 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/arch/um/os-Linux/signal.c: In function 'timer_real_alarm_handler': /kisskb/src/arch/um/os-Linux/signal.c:95:1: warning: the frame size of 2960 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/security/apparmor/policy_unpack.c: In function 'unpack_profile': /kisskb/src/security/apparmor/policy_unpack.c:526:9: warning: 'pos' may be used uninitialized in this function [-Wmaybe-uninitialized] str[pos] = ':'; ^ /kisskb/src/security/apparmor/policy_unpack.c:497:14: note: 'pos' was declared here int c, j, pos, size2 = unpack_strdup(e, &str, NULL); ^ /kisskb/src/lib/lz4/lz4hc_compress.c: In function 'LZ4HC_compress_generic': /kisskb/src/lib/lz4/lz4hc_compress.c:579:1: warning: the frame size of 2144 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ drivers/reset/reset-brcmstb-rescal.o: In function `brcm_rescal_reset_probe': /kisskb/src/drivers/reset/reset-brcmstb-rescal.c:76: undefined reference to `devm_ioremap_resource' drivers/reset/reset-intel-gw.o: In function `intel_reset_probe': /kisskb/src/drivers/reset/reset-intel-gw.c:185: undefined reference to `devm_platform_ioremap_resource' collect2: error: ld returned 1 exit status make[1]: *** [/kisskb/src/Makefile:1077: vmlinux] Error 1 make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 10 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_um-allmodconfig_um-x86_64 # Build took: 0:11:04.213808
