- Adapted the "xencrash-0.2" patch described here:
  
https://www.redhat.com/archives/crash-utility/2006-November/msg00036.html
  This functionality consists of three inter-dependent parts, all of
  while are still under development:
    1) the kexec-tools user package
    2) the kdump kernel patch for xen
    3) the crash utility
  The end result will be a single crash binary that can be used with
  either the xen dom0 vmlinux kernel, or with the xen-syms hypervisor binary,
  with the common vmcore created when either of those two entities crash.

- Fixed the initialization-time, and "sys" command, displays of the system
  memory size when memory nodes have holes.  Without this patch, more memory
  than what is installed may be displayed.  (anderson(a)redhat.com)
