this is a resend of this patch, which I believe is a simple but
useful feature. I have used it extensively to test the kdump
patches which I have been developing with my colleague Magnus Damm.
It is probably useful for other purposes too, and is analogous
to the trigger crashdump feature of Linux's sysrq.

On Linux the sysrq only does anything if kexec is in use and a crash image has been provided (crash_kexec). Perhaps you should do the same and make this part of the Xen portion of your kexec patches?
