Linus Torvalds 38ad9aebe7 Fix ARM profiling/instrumentation configuration
Commit 09cadedbdc ("Combine
instrumentation menus in kernel/Kconfig.instrumentation") broke ARM
profiling support, since ARM has some extra Kconfig options and doesn't
just use the common OPROFILE/KPROBES config options.

Rather than just revert the thing outright, or add ARM-specific
knowledge to the generic Kconfig.instrumentation file (where the only
and whole point was to be generic, not too architecture-specific), this
just makes ARM not use the generic version, since it doesn't suit it.

So create an arm-specific version of Kconfig.instrumentation instead,
and use that.

---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.

Say Y here to enable the extended profiling support mechanisms used
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.

Place an empty function call at each marker site. Can be
dynamically changed for a probe function.
