KVM needs to ensure the guest hypervisor's traps take effect when the vCPU is in a nested context. While supporting infrastructure is in place for most of the EL2 trap registers, MDCR_EL2 is not. Fold the guest's trap configuration into the effective MDCR_EL2. Apply it directly to the in-memory representation as it gets recomputed on every vcpu_load() anyway.

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.
