Having registers that can be interpreted identically in a contiguous I/O area (or at least, following a given stride) is a common way to organize registers, and is used by NVIDIA hardware. Thus, add a way to simply and safely declare such a layout using the register!() macro. Build-time bound-checking is effective for array accesses performed with a constant. For cases where the index cannot be known at compile time, `try_` variants of the accessors are also made available that return `EINVAL` if the access is out-of-bounds.

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 reStructuredText 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.
