Detect unhandleable vectoring in check_emulate_instruction() to prevent infinite retry loops on SVM, and to eliminate the main differences in how VM-Exits during event vectoring are handled on SVM versus VMX. E.g. if the vCPU puts its IDT in emulated MMIO memory and generates an event, without the check_emulate_instruction() change, SVM will re-inject the event and resume the guest, and effectively put the vCPU into an infinite 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.
