[PATCH] Hack mptfusion to work on >4GB machines

fusion needs several separately allocated coherent regions and
requires that they all be in the same 4GB segment.  Obviously this may
fail.  The hack is to force the coherent_dma_mask to 0xffffffff thus
ensuring that all the allocations occur within the first 4GB.  This
hack breaks Altix entirely.
