Now that we use all the available virtual address range, we need to make sure we don't generate VSID such that it overlaps with the reserved vsid range. Reserved vsid range include the virtual address range used by the adjunct partition and also the VRMA virtual segment. We find the context value that can result in generating such a VSID and reserve it early in boot. We don't look at the adjunct range, because for now we disable the adjunct usage in a Linux LPAR via CAS interface.
