Benjamin Herrenschmidt 3a6a04706f 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.
