Ignore kvm-arm.mode if !is_hyp_mode_available(). Specifically, we want to avoid switching kvm_mode to KVM_MODE_PROTECTED if hypervisor mode is not available. This prevents "Protected KVM" cpu capability being reported when Linux is booting in EL1 and would not have KVM enabled. Reasonably though, we should warn if the command line is requesting a KVM mode at all if KVM isn't actually available. Allow "kvm-arm.mode=none" to skip the warning since this would disable KVM 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 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.
