#     dmascc: use proper 'virt_to_bus()' rather than casting to 'int'
#     
#     The old dmascc driver depends on the legacy ISA_DMA_API, and blindly
#     just casts the kernel virtual address to 'int' for set_dma_addr().
#     
#     That works only incidentally, and because the high bits of the address
#     will be ignored anyway. And on 64-bit architectures it causes warnings.
#     
#     Admittedly, 64-bit architectures with ISA are basically dead - I think
#     the only example of this is alpha, and nobody would ever use the dmascc
#     driver there.  But hey, the fix is easy enough, the end result is
#     cleaner, and it's yet another configuration that now builds without
#     warnings.
#     
#     If somebody actually uses this driver on an alpha and this fixes it for
#     you, please email me.  Because that is just incredibly bizarre.
