All of this is the case # for m68k. The exact reasons are unknown, but seem to be related to the # ability of the compiler to evaluate the return value of strlen() and # the resulting execution flow in memcpy_and_pad(). It would be possible # to work around the problem by using sizeof(UTS_RELEASE) instead of # strlen(UTS_RELEASE), but that would only postpone the problem until the # function is called in a similar way. Uninline memcpy_and_pad() instead # to solve the problem for good. # # Suggested-by: Linus Torvalds # Reviewed-by: Geert Uytterhoeven # Acked-by: Andy Shevchenko # Signed-off-by: Guenter Roeck # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 5c4e0a21fae877a7ef89be6dcc6263ec672372b8 # < make -s -j 32 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 32 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- help # make -s -j 32 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- olddefconfig # make -s -j 32 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:11.18-14.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x0: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:15.23-18.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x400000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:19.23-22.6: Warning (unit_address_format): /soc/flash@08000000/partition@0xa00000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:23.23-26.6: Warning (unit_address_format): /soc/flash@08000000/partition@0xfe0000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-4m.dtsi:11.18-14.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x0: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-4m.dtsi:15.23-18.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x3f0000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:11.18-14.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x0: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:15.24-18.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x6000000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:19.24-22.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x6800000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:23.24-26.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x7fe0000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:11.18-14.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x0: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:15.24-18.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x6000000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:19.24-22.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x6800000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-128m.dtsi:23.24-26.6: Warning (unit_address_format): /soc/flash@00000000/partition@0x7fe0000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:11.18-14.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x0: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:15.23-18.6: Warning (unit_address_format): /soc/flash@08000000/partition@0x400000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:19.23-22.6: Warning (unit_address_format): /soc/flash@08000000/partition@0xa00000: unit name should not have leading "0x" /kisskb/src/arch/xtensa/boot/dts/xtfpga-flash-16m.dtsi:23.23-26.6: Warning (unit_address_format): /soc/flash@08000000/partition@0xfe0000: unit name should not have leading "0x" :1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] WARNING: modpost: lib/find_bit_benchmark.o(.text.unlikely+0x0): Section mismatch in reference from the (unknown reference) (unknown) to the variable .init.data:bitmap2 The function (unknown)() references the variable __initdata bitmap2.
