I am trying to dump calling stack in Xen in my codes instead of using
kgdb like tools. oprofile seems to be one possibility.
While oprofile is already included in kernel 2.6.11, I don't
see this option when I do "make ARCH=xen menuconfig". Actually I always
see the call stack dump after I crash the kernel. So I think there are
some codes in kernel that can dump the stack information. But I haven't
find them. :)
Can someone kindly tell me how to do this? Thanks in advance!

linux kernel has a "dump_stack()" function, that helps at least for
the linux kernel context. xen itself hasn't something like that, you
only get the addresses, not the symbols ...
