I was thinking about this yesterday, when, IIRC, a change made by Kan
Liang (IIRC) to a kernel/events/ file, in the kernel proper, triggered a
warning about some casts and I got a warning, since I was in the commig
log CC list.

Since perf is in the kernel sources, and since we have the 'make -C
tools/perf build-test' harness, that would be really great to have it
hooked into the 0day bot...
