In kernel/trace/trace_events_trigger.c --> stacktrace_trigger() -->
__trace_stack() is not defined as per the function definition.
With commit edbaaa13a660
("tracing: Merge irqflags + preemt counter, add RT bits")
the irqflags(flags) and preemption counter(preempt_count()) are
now should be evaluated early by tracing_gen_ctx().
This patch replaces the irqflags and preemption counter
with tracing_gen_ctx().
Fixes: 5e8446e3820c ("tracing: Dump stacktrace trigger to the corresponding instance")
