Continuing the work started in 411f0f3edc ...
This enables code with a dma path, that compiles away, to build without
requiring additional code factoring. It also prevents code that calls
dma_alloc_coherent and dma_free_coherent from linking whereas previously
the code would hit a BUG() at run time. Finally, it allows archs that set
!HAS_DMA to delete their asm/dma-mapping.h file.

The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.

|
You can operate a Linux system on this board by using an M32R
|
|
softmacro core, which is a fully-synthesizable functional model
|
|
described in Verilog-HDL.
|
|
|
|
The Mappi-I board was the first platform, which had been used
|
|
to port and develop a Linux system for the M32R processor.
|
|
Currently, the Mappi-II, an heir to the Mappi-I, is available.

This option reduces the latency of the kernel when reacting to

|
real-time or interactive events by allowing a low priority process to

be preempted even if it is in kernel mode executing a system call.
|

This allows applications to run more reliably even when the system is
|
|
under load.

a system with only one CPU, like most personal computers, say N. If

|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If
|
|
you say Y here, the kernel will run on many, but not all,
|
|
singleprocessor machines. On a singleprocessor machine, the kernel
|
|
will run faster if you say N here.
|
|
|
|
People using multiprocessor machines who say Y here should also say
|
|
Y to "Enhanced Real Time Clock Support", below. The "Advanced Power

Management" code will be disabled if you say Y here.

On PCI systems, the BIOS can be used to detect the PCI devices and

determine their configuration. However, some old PCI motherboards
