This patch removes the unused file parameter from the AbstractMemory. The patch serves to make it easier to transition to a separation of the actual contigious host memory backing store, and the gem5 memory controllers. Without the file parameter it becomes easier to hide the creation of the mmap in the PhysicalMemory, as there are no longer any reasons to expose the actual contigious ranges to the user. To the best of my knowledge there is no use of the parameter, so the change should not affect anyone.
