The ASR8601 SoC combines ARMv8.2 CPUs from ARM with a GIC-500, also from ARM. However, the two are incompatible as the former expose an affinity in the form of (cluster, core, thread), while the latter can only deal with (cluster, core). If nothing is done, the GIC simply cannot route interrupts to the CPUs. Implement a workaround that shifts the affinity down by a level, ensuring the delivery of interrupts despite the implementation mismatch.

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.
