kcov: initial implementation
...
Implement a device (/dev/kcov) that exposes coverage info for the
kernel. This will be especially useful for coverage-based fuzzing (e.g.
syzkaller).
Exclude a lot of functions which would crash/otherwise interfere in the
coverage, including only processing coverage callbacks when not handling
an irq.

cpu: add irq depth counting
...
Add a way of checking if a cpu is in the middle of handling an irq and
how deep it is into it. This will allow for future code to conditionally
run only in/outside interrupts.
