Delete the previous per-vCPU IRTE link prior to modifying the IRTE. If forcing the IRTE back to remapped mode fails, the IRQ is already broken; keeping stale metadata won't change that, and the IOMMU should be sufficiently paranoid to sanitize the IRTE when the IRQ is freed and reallocated. This will allow hoisting the vCPU tracking to common x86, which in turn will allow most of the IRTE update code to be deduplicated.

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.
