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."

+ ---help---
+ Say Y here to get to see options related to performance measurement,
+ system-wide debugging, and testing. This option alone does not add any
+ kernel code.
+
+ If you say N, all options in this submenu will be skipped and
+ disabled. If you're trying to debug the kernel itself, go see the
+ Kernel Hacking menu.

+ by profilers such as OProfile.

+ help
+ OProfile is a profiling system capable of profiling the
+ whole system, include the kernel, kernel modules, libraries,
+ and applications.
+
+ If unsure, say N.

+ bool "Kprobes"
+ depends on KALLSYMS && MODULES
+ depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
+ help
+ Kprobes allows you to trap at almost any kernel address and
+ execute a callback function. register_kprobe() establishes
+ a probepoint and specifies the callback. Kprobes is useful
+ for kernel debugging, non-intrusive instrumentation and testing.
+ If in doubt, say "N".
