Architectures which use generic BUG() have warnings like
kernel/sched/core.c:2692:1: warning: control reaches end of non-void function
[-Wreturn-type]
net/core/ethtool.c:236:1: warning: control reaches end of non-void function
[-Wreturn-type]
Other BUG() implementations
have added unreachable() at end but generic does not. I guess
that is why
it showing these errors. We can silence them using unreachable().
