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

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