Subject[patch 01/10] Create instrumentation directory
Since we already have the Instrumentation menu in
kernel/Kconfig.instrumentation and instrumentation code all over the
kernel tree:

arch/*/oprofile/*.c
kernel/kprobes.c
arch/*/kernel/kprobes.c
kernel/marker.c
kernel/profile.c
kernel/lockdep.c
vm/vmstat.c
block/blktrace.c
We could move them to

instrumentation/
arch/*/instrumentation/
Therefore, we could also move the kprobes and marker samples under

instrumentation/samples/
