If BUG() would be normal function it could be marked as __attribute__((noreturn)).
But it's a macro defined differently depending on architecture and CONFIG_*.
Sometimes it calls panic() which is annotated properly and sometimes it calls
other code....

If you are brave, you could fix all implementations.
