* New upstream version 5.0.6 (see
  http://people.redhat.com/anderson/crash.changelog)
* Fix for support of xendump and Xen kdump dumpfiles from 2.6.27 and and
  later x86_64 kernels.
* Fix for the "s390dbf" command to allow the command's output to be
  redirected to a pipe.
* Fix for the x86 "bt" command to generically recognize the end of trace
  condition for tasks entering the kernel from user-space without having to
  hardwire any more kernel entry point function names. Without the patch, a
  task that took a clock interrupt from user-space and crashed while
  operating on the soft IRQ stack failed with the error message "bt: cannot
  resolve stack trace". (anderson@redhat.com)
* Display the "machine type mismatch" warning when attempting to use a ppc64
  vmlinux file on a non-ppc64 64-bit host. Without the patch, the fact that
  ppc64 vmlinux ELF files are type ET_DYN, and not type ET_EXEC like all of
  the other architectures, was allowing the vmlinux to be accepted without
  the mismatch warning, and would subsequently fail without a meaningful
  explanation being displayed. (anderson@redhat.com)
* Fix for the x86_64 "bt" command if the kdump-generated NMI interrupts a
  multi-threaded task that has just entered kernel space but has not changed
  the RSP stack pointer register from its user-space per-thread stack
  location to the kernel stack. Without the patch, the command follows the
  display of the exception frame on the NMI exception stack with the message
  "WARNING: possibly bogus exception frame", displays the error message "bt:
  cannot transition from exception stack to current process stack", and does
  not display the user-space exception frame. (anderson@redhat.com)
* Added the "set" command to the list of commands acceptable when running
  in --minimal mode. The command is limited to the setting of internal
  variables since there is no task context in that mode.

* Fix for the "vtop" command when run against x86 Xen PAE kernels. Without
  the patch, the "PAGE:" displays (machine and pseudo-physical) contained
  non-zero values in the lower 12 bits, and the translation of the PTE entry
  was incorrect as a result of receiving the incorrect contents in the lower
  12-bits of the PTE entry. (anderson@redhat.com)
* Implemented support for running against live x86_64 pv_ops/Xen guest
  kernels. (anderson@redhat.com)
* Implemented support for xendump ELF dumpfiles generated from x86_64
  pvops/Xen guest kernels. (anderson@redhat.com)
* Implemented support for running against live x86 pv_ops/Xen guest kernels.

* Implemented support for xendump ELF dumpfiles generated from x86 pvops/Xen
  guest kernels. (anderson@redhat.com)
* Determine the bit positions of PG_reserved and PG_slab using the newer
  pageflags enumerator values if available. (anderson@redhat.com)
* Fix to prevent the "repeat" command from keeping a crash session alive if
  the controlling terminal session is killed. (anderson@redhat.com)
