551	  Selecting this option will configure the caches in write-through
552	  mode, as opposed to the default write-back configuration.
553
554	  Since there's sill some aliasing issues on SH-4, this option will
555	  unfortunately still require the majority of flushing functions to

580	---help---
581	  This enables support for systems with more than one CPU. If you have
582	  a system with only one CPU, like most personal computers, say N. If
583	  you have a system with more than one CPU, say Y.
584
585	  If you say N here, the kernel will run on single and multiprocessor
586	  machines, but will use only one CPU of a multiprocessor machine. If
587	  you say Y here, the kernel will run on many, but not all,
588	  singleprocessor machines. On a singleprocessor machine, the kernel
589	  will run faster if you say N here.
590
591	  People using multiprocessor machines who say Y here should also say
592	  Y to "Enhanced Real Time Clock Support", below.
