Currently, we store the addresses of the three areas and the size of the dtl in CPUPPCState. The SLB shadow and DTL are variable sized, with the size being retrieved from within the registered memory area at the hypercall time. This size can later be overwritten with other information, however, so we need to save the size as of registration time. We already do this for the DTL, but not for the SLB shadow, so this patch fixes that. In addition, we change the storage of the VPA information to use fixed size integer types which will make life easier for syncing this data with KVM, which we will need in future.
