[PATCH 0/4] x86/acpi/cppc: Minor clean up for x86 CPPC implementation

From: Huang Rui <ray.huang@amd.com>

Hi all,

While we were fixing the legacy issue below, we found the dependencies
between smpboot and CPPC were not very good. But due to urgent fix for
5.17-rc1, I didn't have much time to provide a complete solution.

https://lore.kernel.org/lkml/YdeWDDCwBQAYnlKb@amd.com/ (local)

In these series, I expand the scope of acpi/cppc_msr to acpi/cppc to cover
the all the CPPC helper functions for x86 ACPI. And then clean up the
smpboot and move CPPC related functions into the acpi/cppc.c. This design
is more straightforward and more clear to handle the CPPC in x86 and
resolve dependency issues between CPPC and smpboot.c.

Thanks,
Ray
