[Crash-utility] crash version 4.0-2.31 is available

[Dave Anderson]

- Bumped crash-internal NR_CPUS for x86 and ia64; added a warning
  message to "recompile crash" and forced an initialization failure
  when the kernel's configured NR_CPUS is greater than the maximum
  allowed NR_CPUS value compiled into crash.
  (maneesh at in.ibm.com, anderson at redhat.com)

- Fix for initialization failure indicating a kernel/memory-source
  mismatch when x86 kernel configures its physical memory start
  address higher than the traditional 1MB starting point.
  (anderson at redhat.com)

- Fix for kernels that have replaced the "system_utsname" data
  structure with contents of the "init_uts_ns" data structure.
  This fixes a "crash: cannot resolve system_utsname" initialization
  failure.  (pbadari at us.ibm.com, anderson at redhat.com)

- Fix for large LKCD dumpfiles that resulted in an initialization
  time failure indicating "fixme, need to add more zones (ZONE_ALLOC)".
  When statically-defined ZONE_ALLOC value is too small, the fix
  expands the zone size dynamically.  (indou.takao at jp.fujitsu.com)

- Fix for "kmem -i" failure when the "all_bdevs" block_device list
  is empty.  Part of the command output would be displayed, followed by
  "kmem: invalid kernel virtual address: 0  type: inode buffer".
  (anderson at redhat.com)

- First pass at supporting a xen hypervisor kexec/kdump vmcore as the
  dumpfile format for the dom0 vmlinux.  Developed/tested OK on an x86
  vmlinux/vmcore set supplied by horms at verge.net.au.  Code for x86_64
  is in place, but untested.  (anderson at redhat.com)

- Also in place, but untested, is initial support for xen x86 PAE
  kernels.  (anderson at redhat.com)
