When we clear the Crypto Control Block (CRYCB) used by a guest level 2, the vSIE shadow CRYCB for guest level 3 must be updated before the guest uses it. We achieve this by using the KVM_REQ_VSIE_RESTART synchronous request for each vCPU belonging to the guest to force the reload of the shadow CRYCB before rerunning the guest level 3.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
