  43           The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  44           You can operate a Linux system on this board by using an M32R
  45           softmacro core, which is a fully-synthesizable functional model
  46           described in Verilog-HDL.
  47
  48           The Mappi-I board was the first platform, which had been used
  49           to port and develop a Linux system for the M32R processor.
  50           Currently, the Mappi-II, an heir to the Mappi-I, is available.

 207           This option reduces the latency of the kernel when reacting to
 208           real-time or interactive events by allowing a low priority process to
 209           be preempted even if it is in kernel mode executing a system call.
 210           This allows applications to run more reliably even when the system is
 211           under load.
 212
 213           Say Y here if you are building a kernel for a desktop, embedded

 226           you have a system with more than one CPU, say Y.
 227
 228           If you say N here, the kernel will run on single and multiprocessor
 229           machines, but will use only one CPU of a multiprocessor machine. If
 230           you say Y here, the kernel will run on many, but not all,
 231           singleprocessor machines. On a singleprocessor machine, the kernel
 232           will run faster if you say N here.
 233
 234           People using multiprocessor machines who say Y here should also say
 235           Y to "Enhanced Real Time Clock Support", below. The "Advanced Power

 304           have BIOS bugs and may crash if this is done. Also, some embedded
 305           PCI-based systems don't have any BIOS at all. Linux can also try to
