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

176 Changes the default page size; use with caution.
