When a kexec'ed kernel boots up, there might be stale unhandled interrupts pending in the interrupt controller. These are delivered as spurious interrupts once the boot CPU enables interrupts. Clear all pending interrupts when the driver is initialized to prevent these spurious interrupts from locking the CPU in an endless loop.

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.
