This patch reworks the irq handling and reporting code for the AP queue interrupt handling to always use the irq info from the queue status. Until now the interrupt status of an AP queue was stored into a bool variable within the ap_queue struct. This variable was set on a successful interrupt enablement and cleared with kicking a reset. However, it may be that the interrupt state is manipulated outband for example by a hypervisor. This patch removes this variable and instead the irq bit from the AP queue status which is always reflecting the current irq state is used.

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.
