# # so we actually do want PHYSMEM_END to be defined a 64-bit type - just # not all ones, and not larger than 'phys_addr_t'. # # The proper fix is probably to not have some kind of default fallback at # all, but just make sure every architecture has a valid MAX_PHYSMEM_BITS. # But in the meantime, this just applies the rule that PHYSMEM_END is the # largest value that fits in a 'phys_addr_t', but does not have the high # bit set in 64 bits. # # Ugly, ugly. # # Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> # Cc: Andrew Morton <akpm@linux-foundation.org> # Cc: Huang Ying <ying.huang@intel.com> # Cc: Thomas Gleixner <tglx@linutronix.de> # 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 f8eb5bd9a818cc5f2a1e50b22b0091830b28cc36 # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allnoconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- allnoconfig # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allnoconfig_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_allnoconfig_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_allnoconfig_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) \| ^~~~~~~~~~~~~~~~~~~~~~~~~ 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/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 /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:3078:2: warning: #warning clone3() entry point is missing, please fix [-Wcpp] 3078 \| #warning clone3() entry point is missing, please fix \| ^~~~~~~ Completed OK # rm -rf /kisskb/build/linus_allnoconfig_sparc64-gcc13 # Build took: 0:01:23.302106
