    This patch adds the kernelcore= parameter for x86.
    
    Once all patches are applied, a new command-line parameter exist and a new
    sysctl.  This patch adds the necessary documentation.

      When "kernelcore" boot option is specified, kernel can't boot up on ia64
      because of an infinite loop.  In addition, the parsing code can be handled
      in an architecture-independent manner.
    
      This patch uses common code to handle the kernelcore= parameter.  It is
      only available to architectures that support arch-independent zone-sizing
      (i.e.  define CONFIG_ARCH_POPULATES_NODE_MAP).  Other architectures will
      ignore the boot parameter.
