So on 64-bit set the end # of the range to be the address immediately past the end of the kernel # page tables, to limit the page table walk to valid addresses. # # Fixes: e084728393a5 ("powerpc/ptdump: Convert powerpc to GENERIC_PTDUMP") # Reported-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /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 c7dee506ec3450717e84518ab3a6a3f2ce755cf6 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # 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=y # Added to kconfig CONFIG_PPC64=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_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # 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 80 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:5140:warning: override: reassigning to symbol CPU_BIG_ENDIAN .config:5140:warning: override: CPU_BIG_ENDIAN changes choice state .config:5143:warning: override: reassigning to symbol SECTION_MISMATCH_WARN_ONLY .config:5144:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:5146:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/arch/powerpc/include/asm/book3s/64/pgtable.h:310, from /kisskb/src/arch/powerpc/include/asm/book3s/64/mmu-hash.h:20, from /kisskb/src/arch/powerpc/include/asm/book3s/64/mmu.h:32, from /kisskb/src/arch/powerpc/include/asm/mmu.h:395, from /kisskb/src/arch/powerpc/include/asm/lppaca.h:46, from /kisskb/src/arch/powerpc/include/asm/paca.h:17, from /kisskb/src/arch/powerpc/include/asm/current.h:13, from /kisskb/src/include/linux/thread_info.h:23, from /kisskb/src/include/asm-generic/preempt.h:5, from ./arch/powerpc/include/generated/asm/preempt.h:1, from /kisskb/src/include/linux/preempt.h:78, from /kisskb/src/include/linux/spinlock.h:51, from /kisskb/src/include/linux/ipc.h:5, from /kisskb/src/include/uapi/linux/sem.h:5, from /kisskb/src/include/linux/sem.h:5, from /kisskb/src/include/linux/compat.h:14, from /kisskb/src/arch/powerpc/kernel/asm-offsets.c:14: /kisskb/src/arch/powerpc/include/asm/book3s/64/pgtable-64k.h: In function 'get_hugepd_cache_index': /kisskb/src/arch/powerpc/include/asm/book3s/64/pgtable-64k.h:60:1: error: no return statement in function returning non-void [-Werror=return-type] 60 \| } \| ^ cc1: some warnings being treated as errors make[2]: * [/kisskb/src/scripts/Makefile.build:117: arch/powerpc/kernel/asm-offsets.s] Error 1 make[1]: * [/kisskb/src/Makefile:1213: prepare0] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:220: __sub-make] Error 2 Command 'make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 # Build took: 0:00:48.563144
