    ide_toggle_bounce did select various strange block bounce limits, including
    not bouncing at all as soon as an iommu is present in the system.  Given
    that the dma_map routines now handle any required bounce buffering except
    for ISA DMA, and the ide code already must handle either ISA DMA or highmem
    at least for iommu equipped systems we can get rid of the block layer
    bounce limit setting entirely.
