[PATCH 00/11] CPU frequency test improvements

[Jeremy Kerr]

These changes rework the CPU frequency tests, mainly for compatiblity with
non-x86 machines.

Patches 1-6 factor out the tests into smaller units, so that we can
selectively enable or disable functionality that's specific to ACPI-based
frequency control, and do a little rework to have a consistent 1 pass/fail
per test run.

Patch 7 is a simple check for the consistency of frequency changes.

Patches 8-10 implement Linux perf support for the test benchmarks, so
that we have meaningful results in the benchmark sets, across different
platforms.

Patch 11 makes the tests a little more usable on large machines.

Questions / comments most welcome.

Cheers,


Jeremy
