CONFIG_GENERIC_PENDING_IRQ requires an architecture specific implementation of irq_force_complete_move() for CPU hotplug. At the moment, only x86 implements this unconditionally, but for RISC-V irq_force_complete_move() is only needed when the RISC-V IMSIC driver is in use and not needed otherwise. To allow runtime configuration of this mechanism, introduce a common irq_force_complete_move() implementation in the interrupt core code, which only invokes the completion function, when a interrupt chip in the hierarchy implements it. Switch X86 over to the new mechanism. 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.
