This means # they can execute scv instructions after AIL is disabled, which causes an # interrupt at an unexpected entry location that crashes the kernel. # # Change the kexec sequence to disable AIL after other CPUs have been # brought down. # # As a refresher, the real-mode scv interrupt vector is 0x17000, and the # fixed-location head code probably couldn't easily deal with implementing # such high addresses so it was just decided not to support that interrupt # at all. # # Fixes: 7fa95f9adaee ("powerpc/64s: system call support for scv/rfscv instructions") # Cc: stable@vger.kernel.org # v5.9+ # Reported-by: Sourabh Jain <sourabhjain@linux.ibm.com> # Closes: https://lore.kernel.org/3b4b2943-49ad-4619-b195-bc416f1d1409@linux.ibm.com # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Tested-by: Gautam Menghani <gautam@linux.ibm.com> # Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> # Link: https://msgid.link/20240625134047.298759-1-npiggin@gmail.com # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 21a741eb75f80397e5f7d3739e24d7d75e619011 # make -s -j 40 ARCH=mips O=/kisskb/build/powerpc-fixes_defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig Using /kisskb/src/arch/mips/configs/generic_defconfig as base Merging /kisskb/src/arch/mips/configs/generic/32r2.config Merging /kisskb/src/arch/mips/configs/generic/el.config Merging /kisskb/src/arch/mips/configs/generic/board-boston.config Merging /kisskb/src/arch/mips/configs/generic/board-marduk.config Merging /kisskb/src/arch/mips/configs/generic/board-ni169445.config Merging /kisskb/src/arch/mips/configs/generic/board-ocelot.config Merging /kisskb/src/arch/mips/configs/generic/board-ranchu.config Merging /kisskb/src/arch/mips/configs/generic/board-sead-3.config Merging /kisskb/src/arch/mips/configs/generic/board-virt.config Merging /kisskb/src/arch/mips/configs/generic/board-xilfpga.config # < make -s -j 40 ARCH=mips O=/kisskb/build/powerpc-fixes_defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 40 ARCH=mips O=/kisskb/build/powerpc-fixes_defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 40 ARCH=mips O=/kisskb/build/powerpc-fixes_defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.17-178.5: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0: '#interrupt-cells' found, but node is not an interrupt provider /kisskb/src/arch/mips/boot/dts/img/boston.dts:136.23-177.6: Warning (interrupt_provider): /pci@14000000/pci2_root@0,0/eg20t_bridge@1,0,0: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/img/boston.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' Completed OK # rm -rf /kisskb/build/powerpc-fixes_defconfig_mipsel-gcc5 # Build took: 0:01:07.128330
