powerpc/mm/radix: Synchronize updates to the process table When writing to the process table, we need to ensure the store is visible to a subsequent access by the MMU. We assume we never have the PID active while doing the update, so a ptesync/isync pair should hopefully be a big enough hammer for our purpose.
