Here's a couple of fixes that should go into 4.15 and possibly
stable kernels as well. Most of the time when you hit the system
reset button, either you're a developer with xmon enabled or
customer with a crash dumper enabled. But if neither is the case,
then the result is currently pretty useless. After these patches
we get nice oops trace on each CPU.
