tracing: always define trace_{irq,preempt}_{enable_disable}
We get a build error in the irqsoff tracer in some configurations:
kernel/trace/trace_irqsoff.c: In function 'trace_preempt_on':
kernel/trace/trace_irqsoff.c:855:2: error: implicit declaration of function 'trace_preempt_enable_rcuidle'; did you mean 'trace_irq_enable_rcuidle'? [-Werror=implicit-function-declaration]
trace_preempt_enable_rcuidle(a0, a1);
The problem is that trace_preempt_enable_rcuidle() has different
definition based on multiple Kconfig symbols, but not all combinations
have a valid definition.
This changes the conditions so that we always get exactly one
definition of each of the four tracing macros. I have not tried
to verify that these definitions are sensible, but now we
can build all randconfig combinations again.
