From 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Thu, 18 Oct 2007 23:41:05 -0700 Subject: Combine instrumentation menus in kernel/Kconfig.instrumentation Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."
