103 On some platforms, there is currently no way for the boot loader
104 to pass arguments to the kernel. For these, you should supply some
105 command-line options at build time by entering them here. At a
106 minimum, you should specify the memory size and the root device
107 (e.g., mem=64M root=/dev/nfs).
110 bool "Multi-Processing support"
112 Enables SMP support in the kernel. If unsure, say "Y"
115 int "Maximum number of CPUs" if SMP
120 This allows you to specify the maximum number of CPUs which this
121 kernel will support. The maximum supported value is 6 and the
122 minimum value which makes sense is 2.
124 This is purely to save memory - each supported CPU adds
125 approximately eight kilobytes to the kernel image.
