GNU Make is fine with # missing rule for phony targets. I also removed the comment which is # wrong irrespective of this commit. # # I minimize the change so it can be easily backported to 4.20.x # # To fix v4.20, please backport e07db28eea38 ("kbuild: fix single target # build for external module"), and then this commit. # # Link: https://bugzilla.kernel.org/show_bug.cgi?id=201891 # Fixes: e07db28eea38 ("kbuild: fix single target build for external module") # Fixes: c3ff2a5193fa ("powerpc/32: add stack protector support") # Fixes: 189af4657186 ("ARM: smp: add support for per-task stack canaries") # Fixes: 0a1213fa7432 ("arm64: enable per-task stack canaries") # Cc: linux-stable <stable@vger.kernel.org> # v4.20 # Reported-by: Samuel Holland <samuel@sholland.org> # Reported-by: Alexey Kardashevskiy <aik@ozlabs.ru> # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> # Tested-by: Alexey Kardashevskiy <aik@ozlabs.ru> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 e00d8880481497474792d28c14479a9fb6752046 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/kbuild_44x_akebono_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/akebono_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/kbuild_44x_akebono_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:152:32: warning: 'levelspread[<Uad20>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:100:6: note: 'levelspread[<Uad20>]' was declared here /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/kernel/trace/trace_dynevent.c: In function 'create_dyn_event': /kisskb/src/kernel/trace/trace_dynevent.c:89:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /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] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: 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:339:21: note: 'pdeo' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here /kisskb/src/arch/powerpc/boot/dts/akebono.dts:251.28-289.5: Warning (pci_bridge): /plb/pciex@10100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:291.28-329.5: Warning (pci_bridge): /plb/pciex@20100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:331.28-369.5: Warning (pci_bridge): /plb/pciex@18100000000: node name is not "pci" or "pcie" /kisskb/src/arch/powerpc/boot/dts/akebono.dts:371.28-409.5: Warning (pci_bridge): /plb/pciex@28100000000: node name is not "pci" or "pcie" arch/powerpc/boot/dts/akebono.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' Completed OK # rm -rf /kisskb/build/kbuild_44x_akebono_defconfig_powerpc-gcc4.6 # Build took: 0:00:34.728421
