By the time mmu_cleanup_all runs it is too late to use # udbg_printf, and calling it will cause PS3 systems to hang. # # Remove all debugging statements from ps3_mm_region_destroy() and # ps3_mm_vas_destroy() and replace any error reporting with calls # to lv1_panic. # # With this change builds with 'DEBUG' defined will not cause kexec # reboots to hang, and builds with 'DEBUG' defined or not will end # in lv1_panic if an error is encountered. # # Signed-off-by: Geoff Levand # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/7325c4af2b4c989c19d6a26b90b1fec9c0615ddf.1589049250.git.geoff@infradead.org # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 9aaaca63114c41ad857bb9889732c0827a1689af # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xC36E6558 WARNING: unmet direct dependencies detected for HOTPLUG_CPU Depends on [n]: SMP [=y] && (PPC_PSERIES [=n] || PPC_PMAC [=n] || PPC_POWERNV [=n] || FSL_SOC_BOOKE [=n]) Selected by [y]: - PM_SLEEP_SMP [=y] && SMP [=y] && (ARCH_SUSPEND_POSSIBLE [=n] || ARCH_HIBERNATION_POSSIBLE [=y]) && PM_SLEEP [=y] # 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 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4719:warning: override: reassigning to symbol STANDALONE .config:4721:warning: override: reassigning to symbol MODULE_SIG .config:4726:warning: override: reassigning to symbol PPC_BOOK3S_64 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] # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-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] /kisskb/src/arch/powerpc/kernel/eeh.c:1707:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] 1707 | static int proc_eeh_show(struct seq_file *m, void *v) | ^~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-next-rand_randconfig+ppc64le_powerpc-gcc9 # Build took: 0:05:47.319043
