help
On some platforms, there is currently no way for the boot loader
to pass arguments to the kernel. For these, you should supply some
command-line options at build time by entering them here. At a
minimum, you should specify the memory size and the root device
(e.g., mem=64M root=/dev/nfs).
config HEXAGON_ANGEL_TRAPS

default n
---help---
Enable angel debug traps (for printk's).
config SMP
bool "Multi-Processing support"
---help---
Enables SMP support in the kernel. If unsure, say "Y"
config NR_CPUS
int "Maximum number of CPUs" if SMP
range 2 6 if SMP
default "1" if !SMP
default "6" if SMP
---help---
This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 6 and the
minimum value which makes sense is 2.
This is purely to save memory - each supported CPU adds
approximately eight kilobytes to the kernel image.
