* switched to ioremap() + normal operations
 * split msnd_fifo_write() (and msnd_fifo_read()) into iomem and normal
   versions (original was even worse - it used to do __user and __iomem
   versions in the same code and in atomic context; when that bogosity
   got fixed, the difference between these cases (now normal memory and
   iomem) had been lost).
