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-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 91288fcc5a7ebb6378f442916299dc20d037aa72 # < make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xB59DD38E # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=n # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_BOOK3E_64=n # Added to kconfig CONFIG_PPC_BOOK3S_64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # yes \n | make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [m]: - OCXL [=m] && PPC_POWERNV [=y] && PCI [=y] && EEH [=y] WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [m]: - OCXL [=m] && PPC_POWERNV [=y] && PCI [=y] && EEH [=y] WARNING: unmet direct dependencies detected for HOTPLUG_PCI_POWERNV Depends on [n]: PCI [=y] && HOTPLUG_PCI [=n] && PPC_POWERNV [=y] && EEH [=y] Selected by [m]: - OCXL [=m] && PPC_POWERNV [=y] && PCI [=y] && EEH [=y] In file included from /kisskb/src/arch/powerpc/xmon/xmon.c:64: /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_powerpc': /kisskb/src/arch/powerpc/xmon/dis-asm.h:16:13: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ~~~^ ~~~~ %.8lx /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_spu': /kisskb/src/arch/powerpc/xmon/dis-asm.h:22:13: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ~~~^ ~~~~ %.8lx /kisskb/src/arch/powerpc/kernel/eeh.c:1773:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] static int proc_eeh_show(struct seq_file *m, void *v) ^~~~~~~~~~~~~ /kisskb/src/drivers/cpufreq/cpufreq.c: In function 'refresh_frequency_limits': /kisskb/src/drivers/cpufreq/cpufreq.c:1125:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/cpufreq/cpufreq.c: In function 'cpufreq_init_policy': /kisskb/src/drivers/cpufreq/cpufreq.c:1090:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/cpufreq/cpufreq.c: In function 'store_scaling_governor': /kisskb/src/drivers/cpufreq/cpufreq.c:792:1: warning: the frame size of 1136 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/cpufreq/powernv-cpufreq.c: In function 'powernv_cpufreq_work_fn': /kisskb/src/drivers/cpufreq/powernv-cpufreq.c:928:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/cpufreq/powernv-cpufreq.c: In function 'powernv_cpufreq_reboot_notifier': /kisskb/src/drivers/cpufreq/powernv-cpufreq.c:896:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ WARNING: vmlinux.o(.text+0x30b8): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
