3743d33edf Tiny clean-up of OPROFILE/KPROBES configuration
Make the Kconfig.instrumentation file a bit easier on the eyes, and use
the new ARCH_SUPPORTS_OPROFILE for x86[-64].

00a5825332 Fix oprofile configuration breakage
The cleanup 09cadedbdc broke the oprofile
configuration for MIPS by allowing oprofile support to be built for
kernel models where oprofile doesn't have a chance in hell to work.

Just a dependecy list on a number of architectures is - surprise - broken
and should as per past discussions probably in most considered to be
broken in most cases.  So I introduce a dependency for the oprofile
configuration on ARCH_SUPPORTS_OPROFILE.

b00296fb78 uml: add !UML dependencies
The previous commit ("uml: keep UML Kconfig in sync with x86") is not
enough, unfortunately.  If we go that way, we need to add dependencies
on !UML for several options.

8256e47cdc Linux Kernel Markers
The marker activation functions sits in kernel/marker.c.  A hash table is used
to keep track of the registered probes and armed markers, so the markers
within a newly loaded module that should be active can be activated at module
load time.

marker_query has been removed. marker_get_first, marker_get_next and
marker_release should be used as iterators on the markers.

09cadedbdc 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."
