technically, profile/oprofile Kconfig stuff is set up incorrectly

as a short follow up to my previous patches, it might be worth
pointing out that profiling in general is defined improperly WRT
Kconfig, since *general* profiling is defined inside the more specific
Kconfig files for *oprofiling*:
$ ls arch/*/oprofile/Kconfig
that makes no sense, as it leads to incorrect Kconfig files like
arch/blackfin/oprofile/Kconfig:
=============================
menu "Profiling support"
depends on EXPERIMENTAL
config PROFILING
bool "Profiling support (EXPERIMENTAL)"
help
Say Y here to enable the extended profiling support mechanisms used
by profilers such as OProfile.
config OPROFILE
tristate "OProfile system profiling (EXPERIMENTAL)"
depends on PROFILING
help
OProfile is a profiling system capable of profiling the
whole system, include the kernel, kernel modules, libraries,
and applications.
If unsure, say N.
config HARDWARE_PM
tristate "Hardware Performance Monitor Profiling"
depends on PROFILING
help
take use of hardware performance monitor to profiling the kernel
and application.
If unsure, say N.
endmenu
==========================
where non-oprofile content (HARDWARE_PM) is now defined within the
oprofile subdirectory.
the whole selection of profiling really should be moved up a level,
with oprofile content as a subdirectory, or something similar.
