For # example panic() will call smp_send_stop() early on which calls # stop_this_cpu() on other CPUs, then later in the reboot path, # pnv_restart() will call smp_send_stop() again, which hangs. # # Fix this by adding a special case to the stop_this_cpu() handler to # decrement the busy count, because it will never return. # # Now that the NMI/non-NMI versions of stop_this_cpu() are different, # split them out into separate functions rather than doing #ifdef tricks # to share the body between the two functions. # # Fixes: 6bed3237624e3 ("powerpc: use NMI IPI for smp_send_stop") # Reported-by: Abdul Haleem <abdhalee@linux.vnet.ibm.com> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # [mpe: Split out the functions, tweak change log a bit] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 ac61c1156623455c46701654abd8c99720bceea1 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/boot/dts/qcom/apq8096-db820c.dtb: Warning (pci_bridge): /soc/agnoc@0/qcom,pcie@610000: node name is not "pci" or "pcie" arch/arm64/boot/dts/qcom/apq8096-db820c.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@1,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@2,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_bridge): /pcie@10003000/pci@3,0: missing bus-range for PCI bridge arch/arm64/boot/dts/nvidia/tegra186-p2771-0000.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/arm64/boot/dts/qcom/msm8996-mtp.dtb: Warning (pci_bridge): /soc/agnoc@0/qcom,pcie@610000: node name is not "pci" or "pcie" arch/arm64/boot/dts/qcom/msm8996-mtp.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' Completed OK # rm -rf /kisskb/build/powerpc-fixes_arm64-defconfig_arm64 # Build took: 0:04:46.200793
