Fix ni_labpc.c to build when CONFIG_ISA_DMA_API is not enabled.

This is a driver that supports both ISA and PCI devices.

Ralf Baechle 6fab3e1fbc Staging: Comedi: Build only on arches providing PAGE_KERNEL_NOCACHE
On architectures that don't define PAGE_KERNEL_NOCACHE, the Comedi driver turns
into tragedy:

  CC [M]  drivers/staging/comedi/drivers.o
drivers/staging/comedi/drivers.c: In function ‘comedi_buf_alloc’:
drivers/staging/comedi/drivers.c:505:41: error: ‘PAGE_KERNEL_NOCACHE’ undeclared (first use in this function)
drivers/staging/comedi/drivers.c:505:41: note: each undeclared identifier is rep orted only once for each function it appears in
make[3]: *** [drivers/staging/comedi/drivers.o] Error 1

Restrict the driver to only those architectures that define PAGE_KERNEL_NOCACHE.

PAGE_KERNEL_NOCACHE is a kludge - some system architectures such as SGI IP27
are even uable to offer uncached operation - at least in the way an unwitting
driver might assume.  I haven't looked in details how the driver is using
the area vmaped with PAGE_KERNEL_NOCACHE but maybe doing it XFS-style using
cached memory and the flush_kernel_vmap_range / invalidate_kernel_vmap_range
APIs in conjunction with the DMA API is a practical alternative.

Ian Abbott 57517878df staging: comedi: addi-data: Don't overwrite read-only data
The drivers for ADDI-DATA cards can override some static parameters for
the board type using information read from EEPROM.  Unfortunately, they
currently write the parameters from the EEPROM back to the shared,
read-only board data!  The problem has been masked during compilation by
type-casting away the const-ness of the data.

This patch changes the code to use an area in the private data for the
board instance to hold the parameters read from EEPROM (after
initializing the parameters from the static board data).  It also
changes the type-casts to the read-only data to preserve the const
qualifier.

Ian Abbott 2f644ccfc5 staging: comedi: Make INSN_BITS behavior consistent across drivers
Most comedi hardware drivers that support the INSN_BITS instruction
ignore the base channel (specified by insn->chanspec) and assume it is
0.  The base channel is supposed to affect how the mask (in data[0]) and
bits (in data[1]) are treated.  Bit 0 applies to the base channel, bit 1
applies to base channel plus 1, etc.

For subdevices with no more than 32 channels, this patch modifies the
chanspec and data before presenting it to the hardware driver, and
modifies the data bits read back by the hardware driver (into data[1]).
This makes it appear to the hardware driver that the base channel was
set to 0.

For subdevices with more than 32 channels, the instruction is left
unmodified, as it is assumed that the hardware driver takes note of the
base channel in this case in order to provide access beyond channel 31.
