armada_370_xp_msi_reenable_percpu() is only defined when CONFIG_PCI_MSI is
enabled, and only called when SMP is enabled.
Without CONFIG_SMP, there are no callers, which results in a build time
warning instead:
drivers/irqchip/irq-armada-370-xp.c:319:13: error: 'armada_370_xp_msi_reenable_percpu' defined but not used [-Werror=unused-function]
319 | static void armada_370_xp_msi_reenable_percpu(void) {}
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mark the function as __maybe_unused to avoid adding more complexity
to the #ifdefs.

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.
