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/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 ff69279a44e9ba876466b7d3ab84d6dbd31cac92 # < make -s -j 10 ARCH=arm O=/kisskb/build/linus_acs5k_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- acs5k_defconfig # make -s -j 10 ARCH=arm O=/kisskb/build/linus_acs5k_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2511:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1833:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_acs5k_defconfig_arm # Build took: 0:00:59.045025
