[Xen-devel] eliminate duplicate stack trace during bad page fault
Other than native i386 code, the page fault handler in the guest for whatever
reason ran a stack_trace even though another one is run from die(). Since screen
space is limited, duplicating (perhaps long) stack traces seems quite wasteful.
Patch removing this duplication below/attached.
