tlbNAPOT hangs due to PBMT making instruction memory uncacheable, and spill logic not working there. Fixed TLBLRU to update recently used on TLBHit rather than CAMHit. Moved coverage exclusions to proper line in pmachecker

Possible fix for Linux bug and bug 203. ImperasDV mismatches in linux boot around 571M instructions after the login prompt.
...
This bug occurs when there are back to back HPTW requests and the first generates an access fault during the walk. The old implementation uses a delayed version of the fault to prevent the HTPW fsm from transitioning out of the IDLE state. Because the first request generates the fault and the second request is pipelined the second request appears as if it also faults so the FSM does not perform the walk.
The new implementation adds a FAULT state. When the HPTW generates an access fault it transitions to this state removes the HPTWStall and then transitions to IDLE. There may still be a remaining bug here if the pipeline is stalled for another reason. However I don't think it is possible by construction. The only possible sources of stalls at this point would be IFU and LSU stalls and both are required to make this condition happen.
