Even though it is uncommon, there are cases where the Exit() EFI boot service might return, e.g., when we were booted via the EFI handover protocol from OVMF and the kernel image was specified on the command line, in which case Exit() attempts to terminate the boot manager, which is not an EFI application itself. So let's drop into an infinite loop instead of randomly executing code that isn't expecting it.

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.
