32 performance and low power across a wide variety of applications.

104 string "Default kernel command string"
107 On some platforms, there is currently no way for the boot loader
108 to pass arguments to the kernel. For these, you should supply some
109 command-line options at build time by entering them here. At a
110 minimum, you should specify the memory size and the root device
111 (e.g., mem=64M root=/dev/nfs).
114 bool "Multi-Processing support"
116 Enables SMP support in the kernel. If unsure, say "Y"
119 int "Maximum number of CPUs" if SMP
124 This allows you to specify the maximum number of CPUs which this
125 kernel will support. The maximum supported value is 6 and the
126 minimum value which makes sense is 2.
128 This is purely to save memory - each supported CPU adds
129 approximately eight kilobytes to the kernel image.
132 prompt "Kernel page size"
133 default PAGE_SIZE_4KB
135 Changes the default page size; use with caution.
