Cover letter [PATCH 0/2] sreset driven panic/oops message printing fixes

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.
