[Buildroot] Newbie: linux kernel config

Hi,

I have multicore machines with greater than 8 CPUs

I would like to support more than the default 8 CPUs  (i.e.  CONFIG_NR_CPUS=8)

When I run make linux-xconfig  and search for the following parameter "X86_BIGSMP"; unable to set.
The search/find actually discovers  "X86_BIGSMP" and gives a description only. :(



Support for big SMP systems with more than 8 CPUs (X86_BIGSMP)

CONFIG_X86_BIGSMP:

This option is needed for the systems that have more than 8 CPUs

Symbol: X86_BIGSMP [=n]
Type : boolean
Prompt: Support for big SMP systems with more than 8 CPUs
Location:
-> Processor type and features
Defined at arch/x86/Kconfig:330
Depends on: X86_32 [=n] && SMP [=y]



How can I find and set this parameter?
Or should I just select  "CONFIG_MAXSMP"  and call it a day?


Thanks in advance for your help.



Cheers,
Ernesto
