From aaef2cad852377f8ed9ac5cc3282c9741f81c7d4 Mon Sep 17 00:00:00 2001 From: Anders Darander Date: Mon, 16 Dec 2013 11:53:20 +0100 Subject: [PATCH] linux.mk: enable options for ktap Certain tracing related options are required to be able to build ktapvm.ko, enable those. Enable CONFIG_FUNTCTION_TRACER as otherwise, CONFIG_EVENT_TRACING won't stick. (Some tracer needs to be enabled for this).
