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/alpha-linux/bin/alpha-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux-ld --version # < git log --format=%s --max-count=1 1c9df907da83812e4f33b59d3d142c864d9da57f # < make -s -j 24 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- defconfig # < make -s -j 24 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- help # make -s -j 24 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- olddefconfig # make -s -j 24 ARCH=alpha O=/kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/alpha-linux/bin/alpha-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: "saved_config" [vmlinux] is COMMON symbol Kernel arch/alpha/boot/vmlinux.gz is ready Completed OK # rm -rf /kisskb/build/linus_alpha-defconfig_alpha-gcc4.9 # Build took: 0:01:00.087743
