commit a9c3ee5d0fdb069b54902300df6ac822027f3b0a upstream. The liointc hardware provides separate Interrupt Status Registers (ISR) for each core. The current code uses always the ISR of core #0, which works during boot because by default all interrupts are routed to core #0. When the interrupt routing changes in the firmware configuration then this causes interrupts to be lost because they are not configured in the corresponding core. Use the core index to access the correct ISR instead of a hardcoded 0.

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.
