This commit modified system reset (sreset) handler # to invoke fadump or kdump (if configured), without pushing dmesg to # pstore. This leaves pstore to have old dmesg data which won't be much # of a help if kdump fails to capture the dump. This patch fixes that by # calling kmsg_dump() before heading to fadump ot kdump. # # Fixes: 4388c9b3a6ee ("powerpc: Do not send system reset request through the oops path") # Reviewed-by: Mahesh Salgaonkar # Reviewed-by: Nicholas Piggin # Signed-off-by: Ganesh Goudar # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190904075949.15607-1-ganeshgr@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e7ca44ed3ba77fc26cf32650bb71584896662474 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/dma/fsldma.c: In function 'fsl_dma_chan_probe': /kisskb/src/drivers/dma/fsldma.c:1165:26: warning: this statement may fall through [-Wimplicit-fallthrough=] chan->toggle_ext_pause = fsl_chan_toggle_ext_pause; ~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/dma/fsldma.c:1166:2: note: here case FSL_DMA_IP_83XX: ^~~~ /kisskb/src/drivers/crypto/talitos.c: In function 'talitos_remove': /kisskb/src/drivers/crypto/talitos.c:3142:4: warning: this statement may fall through [-Wimplicit-fallthrough=] crypto_unregister_aead(&t_alg->algt.alg.aead); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/crypto/talitos.c:3143:3: note: here case CRYPTO_ALG_TYPE_AHASH: ^~~~ In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c: In function 'fsl_diu_ioctl': /kisskb/src/include/linux/device.h:1501:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1287:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1290:2: note: here case MFB_SET_PIXFMT: ^~~~ In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/include/linux/device.h:1501:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1296:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1299:2: note: here case MFB_GET_PIXFMT: ^~~~ INFO: Uncompressed kernel (size 0xe44318) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xf00000) Image Name: Linux-5.3.0-rc2-ge7ca44ed3ba7 Created: Wed Sep 18 03:46:13 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6728083 Bytes = 6570.39 KiB = 6.42 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc8 # Build took: 0:03:26.813958
