#     Fix build errors due to new UIO_MEM_DMA_COHERENT mess
#     
#     Commit 576882ef5e7f ("uio: introduce UIO_MEM_DMA_COHERENT type")
#     introduced a new use-case for 'struct uio_mem' where the 'mem' field now
#     contains a kernel virtual address when 'memtype' is set to
#     UIO_MEM_DMA_COHERENT.
#     
#     That in turn causes build errors, because 'mem' is of type
#     'phys_addr_t', and a virtual address is a pointer type.  When the code
#     just blindly uses cast to mix the two, it caused problems when
#     phys_addr_t isn't the same size as a pointer - notably on 32-bit
#     architectures with PHYS_ADDR_T_64BIT.
#     
#     The proper thing to do would probably be to use a union member, and not
#     have any casts, and make the 'mem' member be a union of 'mem.physaddr'
#     and 'mem.vaddr', based on 'memtype'.
#     
#     This is not that proper thing.  This is just fixing the ugly casts to be
#     even uglier, but at least not cause build errors on 32-bit platforms
#     with 64-bit physical addresses.
