7c1f7e335c Working first cut of the cache changes moving the replay to a save/restore. 
The current implementation is too expensive costing (tag+linelen)*numway flip flops and muxes.

cd75bf98e1 If a trap occurs concurrent with a I/DTLB miss the interlock fsm incorrectly goes into the states to handle the TLB miss. 
This commit fixes this bug by keeping the interlock fsm in the T0_READY state on TrapM.

509a0cd3f8 Fixed bug with interlock fsm. The interlock fsm should suppress bus and cache requests by the cpu 
only at the start of a request.  Pending interrupt was used to start one of these suppressions;
however because of the way the cache's fsm was separated from the bus fsm, the cache now made requests
to the bus fsm.  On a miss with write back, the inital fetch is handled correctly.  However if an
interrupt becam pending then the the next request (eviction) made by the cache was also suppressed.
This keeps the d cache fsm stuck in the STATE_MISS_EVICT_DIRTY state as it think it has made a request
to the bus fsm, but the pending interrupt ignored the request.

The solution is to modify how cpu requests are suppressed.  Instead of relying on pending interrupt
it is better to use interrupt which will be disabled if the dcache is currently processing the evict.

0fddceffa6 Modified the mmu to not mux the lower 12 bits of the physical address and instead directly 
assign from the input non translated virtual address.  Since the lower bits never change there is
no reason to place these lower bits on a longer critical path.
The cache and lsu were previously using the lower bits from the virtual address rather than
the physical address.  This change will allow us to keep the shorter critical path and
reduce the complexity of the lsu, ifu, and cache drawings.
