The HW flags the error which # gets captured by the diagnostics. # # Fix this by making sure to "pull" out any already active pool # first. # # Fixes: 243e25112d06 ("powerpc/xive: Native exploitation of the XIVE interrupt controller") # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Benjamin Herrenschmidt # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 b32e56e5a87a1f9243db92bc7a5df0ffb4627cfb # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc86xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1008000: missing ranges for PCI bridge (or not a bridge) arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1008000/pcie@0: missing ranges for PCI bridge (or not a bridge) arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1008000/pcie@0: missing bus-range for PCI bridge arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1009000: missing ranges for PCI bridge (or not a bridge) arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1009000/pcie@0: missing ranges for PCI bridge (or not a bridge) arch/powerpc/boot/mvme7100.dtb: Warning (pci_bridge): /pcie@f1009000/pcie@0: missing bus-range for PCI bridge arch/powerpc/boot/mvme7100.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x9ace78) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xa00000) Image Name: Linux-4.17.0-rc1-gb32e56e Created: Thu Apr 19 01:51:39 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 4776369 Bytes = 4664.42 kB = 4.56 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc86xx_defconfig_powerpc-5.3 # Build took: 0:01:30.624995
