The types are # compatible, and there's no warning - but the result is just random # garbage. # # No, I don't think we've ever hit that issue in practice, but since we # now have sane infrastructure for doing this right, let's just use it. # It fixes any excessive expansion, and also avoids these kinds of broken # type issues. # # Requested-by: David Laight <David.Laight@aculab.com> # Acked-by: Arnd Bergmann <arnd@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 21b136cc63d2a9ddd60d4699552b69c214b32964 # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- defconfig # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sparc/vdso/vclock_gettime.c:254:1: warning: no previous prototype for '__vdso_clock_gettime' [-Wmissing-prototypes] 254 \| __vdso_clock_gettime(clockid_t clock, struct __kernel_old_timespec ts) \| ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:282:1: warning: no previous prototype for '__vdso_clock_gettime_stick' [-Wmissing-prototypes] 282 \| __vdso_clock_gettime_stick(clockid_t clock, struct __kernel_old_timespec ts) \| ^~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:307:1: warning: no previous prototype for '__vdso_gettimeofday' [-Wmissing-prototypes] 307 \| __vdso_gettimeofday(struct __kernel_old_timeval tv, struct timezone tz) \| ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:343:1: warning: no previous prototype for '__vdso_gettimeofday_stick' [-Wmissing-prototypes] 343 \| __vdso_gettimeofday_stick(struct __kernel_old_timeval tv, struct timezone tz) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker In file included from /kisskb/src/arch/sparc/vdso/vdso32/vclock_gettime.c:22: /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:254:1: warning: no previous prototype for '__vdso_clock_gettime' [-Wmissing-prototypes] 254 \| __vdso_clock_gettime(clockid_t clock, struct __kernel_old_timespec ts) \| ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:282:1: warning: no previous prototype for '__vdso_clock_gettime_stick' [-Wmissing-prototypes] 282 \| __vdso_clock_gettime_stick(clockid_t clock, struct __kernel_old_timespec ts) \| ^~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:307:1: warning: no previous prototype for '__vdso_gettimeofday' [-Wmissing-prototypes] 307 \| __vdso_gettimeofday(struct __kernel_old_timeval tv, struct timezone tz) \| ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:343:1: warning: no previous prototype for '__vdso_gettimeofday_stick' [-Wmissing-prototypes] 343 \| __vdso_gettimeofday_stick(struct __kernel_old_timeval tv, struct timezone tz) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso32/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /kisskb/src/kernel/fork.c: In function '__do_sys_clone3': /kisskb/src/kernel/fork.c:3072:2: warning: #warning clone3() entry point is missing, please fix [-Wcpp] 3072 \| #warning clone3() entry point is missing, please fix \| ^~~~~~~ /kisskb/src/kernel/fork.c:3072:2: warning: #warning clone3() entry point is missing, please fix [-Wcpp] 3072 \| #warning clone3() entry point is missing, please fix \| ^~~~~~~ WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
