Justin C. Miller 2d6987341c [kernel] Make sure not to log from AP idle threads ...

The idle threads for the APs have intentionally tiny stacks. Logging is
currently an absolute hog of stack space, so avoid logging on the idle
stacks as much as possible.

Eventually we should instead just reclaim the physical pages used by
most of the stack instead of making them tiny.
