[Crash-utility] [ANNOUNCE] crash version 5.0.6 is available

[Dave Anderson]

 - Fix for support of xendump and Xen kdump dumpfiles from 2.6.27 and
   and later x86_64 kernels.  Without the patch, the crash session 
   would fail during initialization with the error message "crash: 
   cannot resolve end_pfn".

 - 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".

 - 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.

 - 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.

 - 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.

 - Implemented support for running against live x86_64 pv_ops/Xen guest
   kernels.

 - Implemented support for xendump ELF dumpfiles generated from x86_64 
   pvops/Xen guest kernels.

 - Determine the bit positions of PG_reserved and PG_slab using the
   newer pageflags enumerator values if available.

 - Fix to prevent the "repeat" command from keeping a crash session 
   alive if the controlling terminal session is killed.
