The max VL for nested guests is additionally constrained by the max VL selected by the guest hypervisor. Use that instead of KVM's max VL when running a nested guest. Note that the guest hypervisor's ZCR_EL2 is sanitised against the VM's max VL at the time of access, so there's no additional handling required at the time of use.

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.
