On pSeries machines, operating systems can instantiate "RTAS" (Run-Time Abstraction Services), a runtime component of the firmware which implements a number of low-level, infrequently used operations. On logical partitions under a hypervisor, many of the RTAS functions require hypervisor privilege. For simplicity, therefore, hypervisor systems typically implement the in-partition RTAS as just a tiny wrapper around a hypercall which actually implements the various RTAS functions. This patch implements such a hypercall based RTAS for our emulated pSeries machine. A tiny in-partition "firmware" calls a new hypercall, which looks up available RTAS services in a table.
