This patch adds support for threaded IRQs and handlers through irq::ThreadedRegistration and the irq::ThreadedHandler trait. Threaded interrupts are more permissive in the sense that further processing is possible in a kthread. This means that said execution takes place outside of interrupt context, which is rather restrictive in many ways. Registering a threaded irq is dependent upon having an IrqRequest that was previously allocated by a given device. This will be introduced in subsequent patches.

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.
