When KVM is initialised in protected mode, we must take care to filter certain FFA calls from the host kernel so that the integrity of guest and hypervisor memory is maintained and is not made available to the secure world. As a first step, intercept and block all memory-related FF-A SMC calls from the host to EL3 and don't advertise any FF-A features. This puts the framework in place for handling them properly.

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.
