Instead of marking individual interrupts as safe to be migrated in arbitrary contexts, mark the interrupt chips, which require the interrupt to be moved in actual interrupt context, with the new IRQCHIP_MOVE_DEFERRED flag. This makes more sense because this is a per interrupt chip property and not restricted to individual interrupts. That flips the logic from the historical opt-out to a opt-in model. This is simpler to handle for other architectures, which default to unrestricted affinity setting. It also allows to cleanup the redundant core logic significantly. All interrupt chips, which belong to a top-level domain sitting directly on top of the x86 vector domain are marked accordingly, unless the related setup code marks the interrupts with IRQ_MOVE_PCNTXT, i.e. XEN. No functional change intended.

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.
