mainlining shenanigans
d97c5d4c62
Using struct pci_platform_pm_ops for ACPI adds unnecessary indirection to the interactions between the PCI core and ACPI PM, which is also subject to retpolines. Moreover, it is not particularly clear from the current code that, as far as PCI PM is concerned, "platform" really means just ACPI except for the special casess when Intel MID PCI PM is used or when ACPI support is disabled (through the kernel config or command line, or because there are no usable ACPI tables on the system). To address the above, rework the PCI PM code to invoke ACPI PM functions directly as needed and drop the acpi_pci_platform_pm object that is not necessary any more. Accordingly, update some of the ACPI PM functions in question to do extra checks in case the ACPI support is disabled (which previously was taken care of by avoiding to set the pci_platform_ops pointer in those cases).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
