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/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 ff69279a44e9ba876466b7d3ab84d6dbd31cac92 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_powerpc-allnoconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- allnoconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/linus_powerpc-allnoconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /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] Completed OK # rm -rf /kisskb/build/linus_powerpc-allnoconfig_powerpc # Build took: 0:00:19.968272
