[Crash-utility] Crash setup!

[Jayaraman, Bhaskar]

Hi i want to run crash on a dom0 or paravirtualized guest. Please let me know if there's a patch which I can include with the linux source to build the /dev/crash driver with the xen kernel. Also is there any specific way to build crash command line to be used on a xen kernel.
Any pointers to documentation also will be very useful.
Thanks in advance.
Bhaskar.
