Even though it implements # CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so # KASLR kernels (which are the main target of the feature) do not exist on # powerpc anyway. # # Reported-by: Andreas Schwab <schwab@linux-m68k.org> # Suggested-by: Nicholas Piggin <nicholas.piggin@gmail.com> # Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> # 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 # < git log --format=%s --max-count=1 ff69279a44e9ba876466b7d3ab84d6dbd31cac92 # < make -s -j 8 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- a500_defconfig # make -s -j 8 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/fs/ext4/super.c: In function '__save_error_info': /kisskb/src/fs/ext4/super.c:344:2: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_last_error_func, func, sizeof(es->s_last_error_func)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/fs/ext4/super.c:349:3: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_first_error_func, func, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(es->s_first_error_func)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In function '__xfs_xattr_put_listent', inlined from 'xfs_xattr_put_listent' at /kisskb/src/fs/xfs/xfs_xattr.c:204:2: /kisskb/src/fs/xfs/xfs_xattr.c:142:2: warning: 'strncpy' output may be truncated copying between 5 and 9 bytes from a string of length 9 [-Wstringop-truncation] strncpy(offset, prefix, prefix_len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /kisskb/src/arch/parisc/include/asm/atomic.h:10, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/arch/parisc/include/asm/bitops.h:13, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:11, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:9, from /kisskb/src/drivers/scsi/scsi_debug.c:23: /kisskb/src/drivers/scsi/scsi_debug.c: In function 'resp_start_stop': /kisskb/src/arch/parisc/include/asm/cmpxchg.h:48:3: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr)))__xchg((unsigned long)(x), (ptr), sizeof((ptr)))) /kisskb/src/arch/parisc/include/asm/atomic.h:78:30: note: in expansion of macro 'xchg' #define atomic_xchg(v, new) (xchg(&((v)->counter), new)) ^~~~ /kisskb/src/drivers/scsi/scsi_debug.c:1624:2: note: in expansion of macro 'atomic_xchg' atomic_xchg(&devip->stopped, stop); ^~~~~~~~~~~ /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); } ^~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_a500_defconfig_parisc64 # Build took: 0:01:47.639357
