TTBR1 values have so far been redundant since no users implement any support for split address spaces. Crucially, though, one of the main reasons for wanting to do so is to be able to manage each half entirely independently, e.g. context-switching one set of mappings without disturbing the other. Thus it seems unlikely that tying two tables together in a single io_pgtable_cfg would ever be particularly desirable or useful. Streamline the configs to just a single conceptual TTBR value representing the allocated table. This paves the way for future users to support split address spaces by simply allocating a table and dealing with the detailed TTBRn logistics themselves.

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.
