137 string "Default kernel command string"
140 On some platforms, there is currently no way for the boot loader
141 to pass arguments to the kernel. For these, you should supply some
142 command-line options at build time by entering them here. At a
143 minimum, you should specify the memory size and the root device
144 (e.g., mem=64M root=/dev/nfs).
146 config HEXAGON_ANGEL_TRAPS
147 bool "Use Angel Traps"
150 Enable angel debug traps (for printk's).
153 bool "Multi-Processing support"
155 Enables SMP support in the kernel. If unsure, say "Y"
158 int "Maximum number of CPUs" if SMP
163 This allows you to specify the maximum number of CPUs which this
164 kernel will support. The maximum supported value is 6 and the
165 minimum value which makes sense is 2.
167 This is purely to save memory - each supported CPU adds
168 approximately eight kilobytes to the kernel image.

174 Changes the default page size; use with caution.
