 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.
