Marc Zyngier b0b8b689d7 genirq: Allow architectures to override set_handle_irq() fallback
Some architectures want to provide the generic set_handle_irq() API, but
for structural reasons need to provide their own implementation. For
example, arm64 needs to do this to provide uniform set_handle_irq() and
set_handle_fiq() registration functions.

Make this possible by allowing architectures to provide their own
implementation of set_handle_irq when CONFIG_GENERIC_IRQ_MULTI_HANDLER
is not selected.

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.
