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 <torvalds@linux-foundation.org> # Reviewed-by: Geert Uytterhoeven <geert@linux-m68k.org> # Acked-by: Andy Shevchenko <andriy.shevchenko@intel.com> # Signed-off-by: Guenter Roeck <linux@roeck-us.net> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 5c4e0a21fae877a7ef89be6dcc6263ec672372b8 # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] <stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] /kisskb/src/drivers/tty/serial/sunzilog.c:1128:13: error: 'sunzilog_putchar' defined but not used [-Werror=unused-function] static void sunzilog_putchar(struct uart_port port, int ch) ^ cc1: all warnings being treated as errors make[4]: [/kisskb/src/scripts/Makefile.build:277: drivers/tty/serial/sunzilog.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:540: drivers/tty/serial] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:540: drivers/tty] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1872: drivers] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_sparc-allmodconfig_sparc64 # Build took: 0:06:35.493312
