While you're here...
I'd like to change the whole logic and turn it into a
rendezvous. One CPU, the one panicing can proceed. But
I'd like to add the ability from the debugger to switch
onto a different CPU. Such makes it possible to implement
commands that show control and status registers, perform
function calls on specific CPUs, as well as dump on-chip
TLB entries and cache line contents if the CPU/platform
supports it.
Thoughts?
