55382be055 Completed makefile updates to accelerate the generation of memfiles. There are two makefiles in the 
regression directory.  Makefile calls the submakefiles for generating elf files.

Ross Thompson
6b483e621d 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.

b6ae6fea27 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.

fa0080ca70 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.
