Core duo processor


I'm recompiling kernel (2.6.28-1). I'm not sure which processor type should I choose in menuconfig for my Core Duo (not Core 2) processor (mobile version).
Should it be:
Pentium-4/Celeron(P4-based)/Pentium-4 M/older Xeon ?

I don't see any option for Core Duo there.
cat /proc/cpuinfo

Note that the latest Xeons (Xeon 51xx and 53xx) are not based on the
Netburst core and shouldn't use this option. You can distinguish them
using the cpu family field in /proc/cpuinfo. Family 15 is an older Xeon, Family 6 a newer one.

Select this for Intel Core 2 and newer Core 2 Xeons (Xeon 51xx and 53xx)
CPUs. You can distinguish newer from older Xeons by the CPU family
in /proc/cpuinfo. Newer ones have 6 and older ones 15 (not a typo)
Choose "Core 2/newer Xeon"
