Document that hypervisors must set HCR_EL2.MCE2 and handle MOPS exceptions when they migrate a vCPU to another type of CPU, as Linux may not be able to handle the exception at all times. As one example, when running under nested virtualization, KVM does not handle MOPS exceptions from the nVHE/hVHE EL2 hyp as the hyp is never migrated, so the host hypervisor needs to handle them. There may be other situations (now or in the future) where the kernel can't handle an unexpected MOPS exception, so require that the hypervisor handles them.

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.
