Test Procedure:
- Built first kernel for 1M location with CONFIG_KEXEC enabled.
- Booted into first kernel with command line options crashkernel=48M@16M.
- Built second kernel for 16M location with CONFIG_CRASH_DUMP, and 
  CONFIG_PROC_VMCORE enabled.
- Loaded second kernel with following kexec command.

  kexec -p vmlinux-16M --args-linux --crash-dump --append="root=<root-dev>
  init 1"

- Inserted a module to invoke panic and booted into second kernel.
- Got the dump in /proc/vmcore and copied the /proc/vmcore to disk.
- Booted back to first kernel and ran gdb on stored dump image.
