[patch 02/26] Fix ARM to play nicely with generic Instrumentation menu

The conflicting commit for 
move-kconfiginstrumentation-to-arch-kconfig-and-init-kconfig.patch
is the ARM fix from Linus :

commit 38ad9aebe70dc72df08851bbd1620d89329129ba

He just seemed to agree that my approach (just putting the missing ARM
config options in arch/arm/Kconfig) works too. The main advantage it has
is that it is smaller, does not need a cleanup in the future and does
not break the following patches unnecessarily.

It's just been discussed here

http://lkml.org/lkml/2008/1/15/267

However, Linus might prefer to stay with his own patch and I would
totally understand it that late in the release cycle. Therefore I submit
this for the next release cycle.

After applying this patch,
move-kconfiginstrumentation-to-arch-kconfig-and-init-kconfig.patch
applies nicely in the -mm tree without any modification.
