The VFIO common code doesn't provide the possibility to modify a previous mapping entry in another way than unmapping and mapping again with new properties. To avoid -EEXIST DMA mapping error, we introduce a GHashTable to store S390IOTLBEntry instances in order to cache the mapped entries. When intercepting rpcit instruction, ignore the identical mapped entries to avoid doing map operations multiple times and do unmap and re-map operations for the case of updating the valid entries.
