6	  Enable this to allow the userspace driver core code to be
7	  built.  This code allows userspace programs easy access to
8	  kernel interrupts and memory locations, allowing some drivers
9	  to be written in userspace.  Note that a small kernel driver
10	  is also required for interrupt handling to work properly.

31	  Platform driver for Userspace I/O devices, including generic
32	  interrupt handling code. Shared interrupts are not supported.
33
34	  This kernel driver requires that the matching userspace driver
35	  handles interrupts in a special way. Userspace is responsible
36	  for acknowledging the hardware device if needed, and re-enabling
37	  interrupts in the interrupt controller using the write() syscall.

47
48	  Memory regions can be specified with the same platform device
49	  resources as the UIO_PDRV drivers, but dynamic regions can also
50	  be specified.
51	  The number and size of these regions is static,
52	  but the memory allocation is not performed until
53	  the associated device file is opened. The
54	  memory is freed once the uio device is closed.

67	  ports instead of memory mapped I/O. In order to make it
68	  possible for UIO to work with this device a utility, uioport,
