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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 e7ca44ed3ba77fc26cf32650bb71584896662474 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc834x_itx_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 83xx/mpc834x_itx_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc834x_itx_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' 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:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:613:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x5cb374) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5cb374) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.3.0-rc2-ge7ca44ed3ba7 Created: Wed Sep 18 02:39:58 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2944526 Bytes = 2875.51 KiB = 2.81 MiB Load Address: 00600000 Entry Point: 00600290 INFO: Uncompressed kernel (size 0x5bacc8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.3.0-rc2-ge7ca44ed3ba7 Created: Wed Sep 18 02:39:58 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2944486 Bytes = 2875.47 KiB = 2.81 MiB Load Address: 00600000 Entry Point: 00600290 Image Name: Linux-5.3.0-rc2-ge7ca44ed3ba7 Created: Wed Sep 18 02:39:58 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2914831 Bytes = 2846.51 KiB = 2.78 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_83xx_mpc834x_itx_defconfig_powerpc-gcc4.6 # Build took: 0:00:22.617745
