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/alpha-linux/bin/alpha-linux-gcc --version # < git log --format=%s --max-count=1 ff69279a44e9ba876466b7d3ab84d6dbd31cac92 # < make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux- defconfig # make -s -j 8 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/alpha/kernel/osf_sys.c: In function '__do_sys_osf_utsname': /kisskb/src/arch/alpha/kernel/osf_sys.c:532:6: warning: unused variable 'error' [-Wunused-variable] /kisskb/src/arch/alpha/kernel/osf_sys.c: In function '__do_sys_osf_getdomainname': /kisskb/src/arch/alpha/kernel/osf_sys.c:563:11: warning: unused variable 'err' [-Wunused-variable] /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/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 WARNING: "saved_config" [vmlinux] is COMMON symbol Kernel arch/alpha/boot/vmlinux.gz is ready Completed OK # rm -rf /kisskb/build/linus_alpha-defconfig_alpha # Build took: 0:00:55.510601
