[POWERPC] spufs: serialize SLB invalidation against SLB loading
There is a potential race between flushes of the entire SLB in the MFC
and the point where new entries are being established. The problem is
that we might put a ESID entry into the MFC SLB when the VSID entry has
just been cleared by the global flush.
This can be circumvented by holding the register_lock throughout both
the flushing and the creation of SLB entries.
