Log Message:
powerpc/oea: trap: pmap_{pte,ste}_spill() even in the interrupt context

Page table for oea is something like L2 TLB on memory; kernel and
processes share its entries, and process entries can be spilled out.

As done for MMU based on software-managed TLB, we need to restore
such entries even in the interrupt context.

Note that pmap_pte_spill() require no resouce to restore entries.
Still-not-implemented pmap_ste_spill() for OEA64 should also.
