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

 232           This option reduces the latency of the kernel when reacting to
 233           real-time or interactive events by allowing a low priority process to
 234           be preempted even if it is in kernel mode executing a system call.
 235           This allows applications to run more reliably even when the system is
 236           under load.

 247
 248           If you say N here, the kernel will run on single and multiprocessor
 249           machines, but will use only one CPU of a multiprocessor machine. If
 250           you say Y here, the kernel will run on many, but not all,
 251           singleprocessor machines. On a singleprocessor machine, the kernel
 252           will run faster if you say N here.
 253
 254           People using multiprocessor machines who say Y here should also say
