x86/PV: '0' debug key stack dumping adjustments

[PATCH 0/3] x86/PV: '0' debug key stack dumping adjustments

Posted by Jan Beulich 3 years, 2 months ago

Having played with '0' for PVH quite a bit lately, it just so happened
that I also tried it with PV, finding that it has been broken for quite
some time.

1: make '0' debug key dump Dom0's stacks again
2: replace assertions in '0' debug key stack dumping
3: drop "vcpu" local variable from show_guest_stack()
