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

167 Changes the default page size; use with caution.
