While protected KVM is installed, start trapping all host SMCs. For now these are simply forwarded to EL3, except PSCI CPU_ON/CPU_SUSPEND/SYSTEM_SUSPEND which are intercepted and the hypervisor installed on newly booted cores. Create new constant HCR_HOST_NVHE_PROTECTED_FLAGS with the new set of HCR flags to use while the nVHE vector is installed when the kernel was booted with the protected flag enabled. Switch back to the default HCR flags when switching back to the stub vector.

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.
