IA64: fix swiotlb alloc_coherent for non DMA_64BIT_MASK devices, fix
Because dma_alloc_coherent() always required DMA zone even if DMA is
NOT necessary, FUJITA Tomonori posted a patch to fix it:
http://marc.info/?l=linux-ia64&m=123314730923356&w=2
However, this fix needs one more patch to fix completely.
I tested and confirmed dma_alloc_coherent() returns
correct zone after applied following patch.
