Ard Biesheuvel 75c5a713ab efi/x86: Merge the setup_efi_pci32() and setup_efi_pci64() routines 
After merging the 32-bit and 64-bit versions of the code that invokes
the PCI I/O protocol methods to preserve PCI ROM images in commit:

  2c3625cb9f ("efi/x86: Fold __setup_efi_pci32() and __setup_efi_pci64() ...")

there are still separate code paths for 32-bit and 64-bit, where the only
difference is the size of a EFI_HANDLE. So let's parameterize a single
implementation for that difference only, and get rid of the two copies of
the code.

While at it, rename __setup_efi_pci() to preserve_pci_rom_image() to
better reflect its purpose.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
