[PATCH v3 00/18] amd-pstate cleanups

[Mario Limonciello <superm1@kernel.org>]

From: Mario Limonciello <mario.limonciello@amd.com>

This series overhauls locking and drops many unnecessarily cached
variables.

Debugging messages are also dropped in favor of more ftracing.

This series is based off superm1/linux.git bleeding-edge branch.

v2->v3:
 * Mostly pick up tags
 * Add new patch 1/18 that fixes a KBZ issue (see patch for detail)
 * Fixup for min_freq issue in dropping cached values patch
 * Fixup for unit tests to only run on online CPUs
