> Subject: [PATCH] Kconfig: remove HAVE_LATENCYTOP_SUPPORT
>
> As illustrated by a3afe70b83fd ("[S390] latencytop s390 support."),
> HAVE_LATENCYTOP_SUPPORT is defined by an architecture to advertise an
> implementation of save_stack_trace_tsk.
>
> However, as of 9212ddb5eada ("stacktrace: provide save_stack_trace_tsk()
> weak alias") a dummy implementation is provided if STACKTRACE=y.
> Given that LATENCYTOP already depends on STACKTRACE_SUPPORT and selects
> STACKTRACE, we can remove HAVE_LATENCYTOP_SUPPORT altogether.
