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/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux-ld --version # < git log --format=%s --max-count=1 5c4e0a21fae877a7ef89be6dcc6263ec672372b8 # < make -s -j 32 ARCH=parisc O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- generic-64bit_defconfig # < make -s -j 32 ARCH=parisc O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- help # make -s -j 32 ARCH=parisc O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- olddefconfig # make -s -j 32 ARCH=parisc O=/kisskb/build/linus_generic-64bit_defconfig_parisc64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- In file included from <command-line>: /kisskb/src/include/linux/sched.h: In function 'task_cpu': /kisskb/src/include/linux/sched.h:2129:38: error: 'const struct thread_info' has no member named 'cpu' return READ_ONCE(task_thread_info(p)->cpu);
