Improved guest backtraces belong in the xenctx utility 
(tools/xentrace/xenctx.c). It already has the clear advantage that it 
can print kernel symbols as well as addresses. The stack dump code in 
Xen is mainly for very early crashes in dom0, and it's quite sufficient 
for that.
So, if you want a frame-walking mode, put it in xenctx.
