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-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 e7ca44ed3ba77fc26cf32650bb71584896662474 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: vmlinux.o(.text+0x31dc): 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().
