Re: [Xen-devel] [Patch] [RFC] avoid debugger_trap when we don't expect

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

This doesn't need to be fixed on x86 -- the int3 handler will return
silently if the debugger is not configured. It would be nice if the ia64
handler would do the same. If that is not possible then change only ia64
code and if you need to be able to probe gdbstub configuration then add a
public function to do that rather than grope at internal state. The same
goes for powerpc, *if* it is broken in the first place.
