On successful # extraction of physical address it wrongly sets "handled = 1" which # means this UE error has been recovered. Since MCE handler gets return # value as handled = 1, it assumes that error has been recovered and # goes back to same NIP. This causes MCE interrupt again and again in a # loop leading to hard lockup. # # Also, initialize phys_addr to ULONG_MAX so that we don't end up # queuing undesired page to hwpoison. # # Without this patch we see: # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # ... # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # Memory failure: 0x20181a08: recovery action for dirty LRU page: Recovered # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # ... # Watchdog CPU:38 Hard LOCKUP # # After this patch we see: # # Severe Machine check interrupt [Not recovered] # NIP: [00007fffaae585f4] PID: 7168 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffaafe28ac # Physical address: 00002017c0bd0000 # find[7168]: unhandled signal 7 at 00007fffaae585f4 nip 00007fffaae585f4 lr 00007fffaae585e0 code 4 # Memory failure: 0x2017c0bd: recovery action for dirty LRU page: Recovered # # Fixes: 01eaac2b0591 ("powerpc/mce: Hookup ierror (instruction) UE errors") # Fixes: ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors") # Cc: stable@vger.kernel.org # v4.15+ # Signed-off-by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> # Signed-off-by: Balbir Singh <bsingharora@gmail.com> # Reviewed-by: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 75ecfb49516c53da00c57b9efe48fa3f5504a791 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allmodconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/sound/aoa/codecs/onyx.c: In function 'onyx_snd_single_bit_get': /kisskb/src/sound/aoa/codecs/onyx.c:380:37: warning: 'c' may be used uninitialized in this function [-Wmaybe-uninitialized] ucontrol->value.integer.value[0] = !!(c & mask) ^ polarity; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/drivers/ata/ahci_qoriq.c: In function 'ahci_qoriq_hardreset': /kisskb/src/arch/powerpc/include/asm/io.h:623:3: warning: 'px_is' may be used uninitialized in this function [-Wmaybe-uninitialized] ppc_pci_io.name al; \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:14: note: 'px_is' was declared here u32 px_cmd, px_is, px_val; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/arch/powerpc/include/asm/io.h:142:2: warning: 'px_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn" %1,%y0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:6: note: 'px_cmd' was declared here u32 px_cmd, px_is, px_val; ^ WARNING: vmlinux.o(.text+0x37828c): Section mismatch in reference from the function .devm_memremap_pages() to the function .meminit.text:.arch_add_memory() The function .devm_memremap_pages() references the function __meminit .arch_add_memory().
