In subsequent patches we'll use a transient pgd during the primary cpu's boot process. To make this work while allowing secondary cpus to use the swapper_pg_dir, we need to pass the relevant TTBR1 pgd as a parameter to __enable_mmu(). This patch updates __enable__mmu() to take this as a parameter, updating callsites to pass swapper_pg_dir for now. There should be no functional change as a result of this patch.

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.
