SLOF (guest firmware # used by QEMU) currently doesn't do this so the zImage is not aware of # the initrd location. This can result in initrd corruption either # though the zImage extracting the vmlinux over the initrd, or by the # vmlinux overwriting the initrd when relocating itself. # # QEMU does put the linux,initrd-start and linux,initrd-end properties # into the devicetree to vmlinux to find the initrd. So we can work # around the problem by also looking for those properties in the zImage. # # Cc: stable@vger.kernel.org # Signed-off-by: Oliver O'Halloran # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191023013635.2512-1-oohall@gmail.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 91288fcc5a7ebb6378f442916299dc20d037aa72 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_virtex5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/virtex5_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_virtex5_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/virtex440-ml510.dts:335.37-439.6: Warning (pci_bridge): /plb@0/plbv46-pci@85e00000: node name is not "pci" or "pcie" arch/powerpc/boot/dts/virtex440-ml510.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x55f7f0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.5.0-rc5+ Created: Thu Jan 16 07:20:47 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2785955 Bytes = 2720.66 KiB = 2.66 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_44x_virtex5_defconfig_powerpc-gcc5 # Build took: 0:01:17.225699
