This adds code to branch around the parts that radix guests don't need - clearing and loading the SLB with the guest SLB contents, saving the guest SLB contents on exit, and restoring the host SLB contents. Since the host is now using radix, we need to save and restore the host value for the PID register. On hypervisor data/instruction storage interrupts, we don't do the guest HPT lookup on radix, but just save the guest physical address for the fault (from the ASDR register) in the vcpu struct.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
