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

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
