James Morse acf9ef8d1b arm64: acpi: Move get_cpu_for_acpi_id() to a header 
[ Upstream commit 8d34b6f17b ]

ACPI identifies CPUs by UID. get_cpu_for_acpi_id() maps the ACPI UID
to the Linux CPU number.

The helper to retrieve this mapping is only available in arm64's NUMA
code.

Move it to live next to get_acpi_id_for_cpu().

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.
