Note that moving percpu.h # around didn't change anything and that removing it entirely broke # differently. When backporting, such options might still be considered # if this patch fails to help. # # [ It turns out that an alternate fix seems to be to just remove the # troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h> # that causes the circular dependency. # # But we might as well do the whole belt-and-suspenders thing, and # minimize inclusion in <linux/random.h> too. Either will fix the # problem, and both are good changes. - Linus ] # # Reported-by: Daniel Díaz <daniel.diaz@linaro.org> # Reported-by: Kees Cook <keescook@chromium.org> # Tested-by: Marc Zyngier <maz@kernel.org> # Fixes: f227e3ec3b5c # Cc: Stephen Rothwell <sfr@canb.auug.org.au> # Signed-off-by: Willy Tarreau <w@1wt.eu> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 1c9df907da83812e4f33b59d3d142c864d9da57f # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- tegra_defconfig # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 48 ARCH=arm O=/kisskb/build/linus_tegra_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- In file included from /kisskb/src/include/linux/random.h:14:0, from /kisskb/src/arch/arm/kernel/signal.c:8: /kisskb/src/arch/arm/include/asm/percpu.h: In function '__my_cpu_offset': /kisskb/src/arch/arm/include/asm/percpu.h:29:34: error: 'current_stack_pointer' undeclared (first use in this function) : "Q" ((const unsigned long )current_stack_pointer)); ^ /kisskb/src/arch/arm/include/asm/percpu.h:29:34: note: each undeclared identifier is reported only once for each function it appears in make[2]: * [/kisskb/src/scripts/Makefile.build:281: arch/arm/kernel/signal.o] Error 1 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1756: arch/arm/kernel] Error 2 make[1]: * Waiting for unfinished jobs....
