From da48d094ce5d7c7dcdad9011648a81c42fd1c2ef Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 15 Jan 2016 16:58:07 -0800 Subject: [PATCH] Kconfig: remove HAVE_LATENCYTOP_SUPPORT As illustrated by commit 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.
