NOMAP irq domains use the revmap_size field to indicate the maximum hwirq number the domain accepts. This is a bit confusing as revmap_size is usually used to indicate the size of the revmap array, which a NOMAP domain doesn't have. Instead, use the hwirq_max field which has the correct semantics, and keep revmap_size to 0 for a NOMAP domain.

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.
