The kdump kernel then runs with the PCR # set and causes problems. The symptom in the kdump kernel (also seen in # petitboot after fast-reboot) is early userspace programs taking # sigills on newer instructions (seen in libc). # # Signed-off-by: Michael Neuling # Cc: stable@vger.kernel.org # 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 faf37c44a105f3608115785f17cbbf3500f8bc71 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n | make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/sound/aoa/codecs/onyx.c: In function 'onyx_snd_single_bit_get': /kisskb/src/sound/aoa/codecs/onyx.c:380:37: warning: 'c' may be used uninitialized in this function [-Wmaybe-uninitialized] ucontrol->value.integer.value[0] = !!(c & mask) ^ polarity; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/drivers/ata/ahci_qoriq.c: In function 'ahci_qoriq_hardreset': /kisskb/src/arch/powerpc/include/asm/io.h:623:3: warning: 'px_is' may be used uninitialized in this function [-Wmaybe-uninitialized] ppc_pci_io.name al; \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:14: note: 'px_is' was declared here u32 px_cmd, px_is, px_val; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/arch/powerpc/include/asm/io.h:142:2: warning: 'px_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn" %1,%y0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:6: note: 'px_cmd' was declared here u32 px_cmd, px_is, px_val; ^ WARNING: vmlinux.o(.text+0x37830c): Section mismatch in reference from the function .devm_memremap_pages() to the function .meminit.text:.arch_add_memory() The function .devm_memremap_pages() references the function __meminit .arch_add_memory().
