Restore a sanity check # in the soft irq code that had to be disabled for this case, by commit # 4da1f79227ad4 ("powerpc/64: Disable irq restore warning for now"). # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux-ld --version # < git log --format=%s --max-count=1 ae02efbc3fcbabd9723c31c59db0cc4ce75ee22d # < make -s -j 24 ARCH=alpha O=/kisskb/build/powerpc-next_alpha-defconfig_alpha CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux- defconfig # make -s -j 24 ARCH=alpha O=/kisskb/build/powerpc-next_alpha-defconfig_alpha CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/alpha-linux/bin/alpha-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: 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:337:21: note: 'pdeo' was declared here /kisskb/src/mm/mprotect.c: In function 'change_pte_range': /kisskb/src/mm/mprotect.c:42:20: warning: unused variable 'mm' [-Wunused-variable] /kisskb/src/net/ipv4/ip_output.c: In function '__ip_append_data': /kisskb/src/include/linux/skbuff.h:1397:6: warning: 'extra_uref' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/ipv4/ip_output.c:885:14: note: 'extra_uref' was declared here WARNING: "saved_config" [vmlinux] is COMMON symbol Kernel arch/alpha/boot/vmlinux.gz is ready Completed OK # rm -rf /kisskb/build/powerpc-next_alpha-defconfig_alpha # Build took: 0:00:45.638677
