Patch1:
The first patch is to address the concerns mentioned by Limonciello,
Mario i.e to address the issue of
"Probing registers that don't match the same mailboxes randomly on
client or embedded parts might lead to unexpected behaviors".
Because of some limitations, instead of the methods suggested by Mario,
family check is added to differentiate server socs and client socs.
This check is only for backward compatibility, Going forward all
systems will have ACPI based probing only.
Thanks! Hans, please drop the PM profile patch from your review queue
in favor of this series instead.
Patch2:
The second patch splits ACPI code into separate file there by removing the
dependency of ACPI in Kconfig.
This is based on the suggestion from Ilpo Jarvinen.
Patch3:
The third patch makes HSMP as "default m" so that anyone who uses standard
distros will be able to use HSMP by dynamically loading it.
