[PATCH v3 0/6] Improve usability for amd-pstate

[Mario Limonciello]

There has recently been some news coverage about `amd-pstate` being in
5.17, but this news also mentioned that it's a bit difficult to use.

You need to either block init calls, or compile the module into the kernel
to force it to take precedence over acpi-cpufreq.

This series aims to improve the usability of amd-pstate so that distros
can compile as a module, but users can still use it (relatively) easily.

A new module parameter is included that will force amd-pstate to take
precedence and a module table to let it load automatically on such
systems.

By default with this series it will replace acpi-cpufreq no matter the
module load order.  If users want to prefer acpi-cpufreq when amd-pstate
is a module they can make a modprobe configuration file.

/etc/modprobe.d/amd-pstate.conf:

options amd-pstate replace=0

Mario Limonciello (6):
  cpufreq: Export acpu_cpufreq_exit for other drivers to call
  cpufreq: amd-pstate: Only show shared memory solution message once
  cpufreq: amd-pstate: Move cpufreq driver check later
  cpufreq: amd-pstate: Allow replacing acpi-cpufreq when loaded
  cpufreq: amd-pstate: Add a module device table
  cpufreq: amd-pstate: Default to replace acpi-cpufreq
