Compiling Kernel for 24 CPU threads

I've been looking around but can't find an answer to this yet.  How can I compile a x86_64 kernel for 24 CPUs?  By default in the x86_64 config is set to CONFIG_NR_CPUS=16.

Thanks in advance!

Use ABS to do it (see the wiki) or use a pre-made kernel from the AUR.  See kernel26-ck from my sig for example.  Just enable the menuconfig option and you can customize the entire thing if you wish.
