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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 ae02efbc3fcbabd9723c31c59db0cc4ce75ee22d # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # Added to kconfig CONFIG_NUMA=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig+NO_NUMA_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-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/net/netfilter/nf_nat_masquerade.c:15:21: warning: 'masq_refcnt6' defined but not used [-Wunused-variable] static unsigned int masq_refcnt6 __read_mostly; ^ /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1633:6: note: 'oldval' was declared here int oldval, ret; ^ WARNING: vmlinux.o(.text+0x340c): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
