Test-Procedure:
- Built first kernel with CONFIG_KEXEC enabled.
- Booted first kernel with command line option "crashkernel=64M@16M"
- Built second kernel for 16M physical start location with CONFIG_CRASH_DUMP, and
  CONFIG_PROC_VMCORE enabled.
- Loaded second kernel with following kexec command.
  kexec -p /boot/vmlinux-kdump --initrd=/boot/initrd-kdump  --args-linux
  --append="root=/dev/sda2 selinux=0  ip=9.47.67.223:9.47.67.50:9.47.67.1:255.255.255.0
  resume=/dev/sda6 crashkernel=64M@16M showopts console=tty0 console=ttyS0,115200n8"
- Invoked kdump using sysrq-c and second kernel booted.
- Copied /proc/vmcore to disk and rebooted back to the first kernel.
