+config OPROFILE

+       depends on PROFILING
+       depends on HAVE_OPROFILE
+       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 KPROBES
+       bool "Kprobes"
+       depends on KALLSYMS && MODULES
+       depends on HAVE_KPROBES
+       help
+         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".
+
+config HAVE_EFFICIENT_UNALIGNED_ACCESS
+       def_bool n
+       help
+         Some architectures are unable to perform unaligned accesses
+         without the use of get_unaligned/put_unaligned. Others are
+         unable to perform such accesses efficiently (e.g. trap on
+         unaligned access and require fixing it up in the exception
+         handler.)
+
+         This symbol should be selected by an architecture if it can
+         perform unaligned accesses efficiently to allow different
+         code paths to be selected for these cases. Some network
+         drivers, for example, could opt to not fix up alignment
+         problems with received packets if doing so would not help
+         much.
+
+         See Documentation/unaligned-memory-access.txt for more
+         information on the topic of unaligned memory accesses.
