Subject: iommu sg merging: call blk_queue_segment_boundary in __scsi_alloc_queue
From: FUJITA Tomonori <[EMAIL PROTECTED]>
request_queue and device struct must have the same value of a segment
size limit. This patch adds blk_queue_segment_boundary in
__scsi_alloc_queue so LLDs don't need to call both
blk_queue_segment_boundary and set_dma_max_seg_size. A LLD can change
the default value (64KB) can call device_dma_parameters accessors like
pci_set_dma_max_seg_size when allocating scsi_host.
