On deactivating traps, restore the value of mdcr_el2 from the newly created and preserved host value vcpu context, rather than directly reading the hardware register. Up until and including this patch the two values are the same, i.e., the hardware register and the vcpu one. A future patch will be changing the value of mdcr_el2 on activating traps, and this ensures that its value will be restored. No functional change intended.

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.
