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.

If you say N, all options in this submenu will be skipped and

Kprobes allows you to trap at almost any kernel address and

execute a callback function. register_kprobe() establishes

a probepoint and specifies the callback. Kprobes is useful

for kernel debugging, non-intrusive instrumentation and testing.

If in doubt, say "N".
