This two patches corrects PAGE_OFFSET for generated vmcore. Original code uses fix PAGE_OFFSET: 0xc0000000. For kernel with CONFIG_VMSPLIT_1G/2G, generated /proc/vmcore is incorrect. See discussion: http://lists.infradead.org/pipermail/kexec/2014-May/011844.html The first patch detects page_offset dynamically according to /proc/kallsyms, the second patch intorduces a --page-offset option for systems without KALLSYMS or /proc Wang Nan (2): kexec-tools: detect page_offset dynamically kexec-tools: add --page-offset option for ARM kexec/arch/arm/crashdump-arm.c | 64 ++++++++++++++++++++++++++++++++++- kexec/arch/arm/crashdump-arm.h | 4 ++- kexec/arch/arm/include/arch/options.h | 4 ++- kexec/arch/arm/kexec-zImage-arm.c | 7 ++++ 4 files changed, 76 insertions(+), 3 deletions(-) -- 1.8.4
