Pass XFD_ERR via KVM's exception payload mechanism when injecting an #NM after interception so that XFD_ERR can be propagated to FRED's event_data field without needing a dedicated field (which would need to be migrated). For non-FRED vCPUs, this is a glorified NOP as kvm_deliver_exception_payload() will simply do nothing (which is desirable and correct).

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.
