OProfile is a profiling system capable of profiling the
whole system, include the kernel, kernel modules, libraries,
Instruction-Based Sampling (IBS) is a new profiling
technique that provides rich, precise program performance
information. IBS is introduced by AMD Family10h processors

Some architectures are unable to perform unaligned accesses
without the use of get_unaligned/put_unaligned. Others are

The <linux/clk.h> calls support software clock gating and
thus are a key power management tool on many systems.
