warning: (LATENCYTOP && HAVE_LATENCYTOP_SUPPORT) selects SCHED_DEBUG which has unmet direct dependencies (DEBUG_KERNEL && PROC_FS)
warning: (LATENCYTOP && HAVE_LATENCYTOP_SUPPORT) selects SCHEDSTATS which has unmet direct dependencies (DEBUG_KERNEL && PROC_FS)

Add depends on STACKTRACE_SUPPORT for 'select STACKTRACE'.
Add depends on PROC_FS since that is where the output goes.
