All, Quick question to all of you who have used Hyperthreaded CPUs : if you boot a linux kernel on a 4-way SMP box w/ Hyperthreading (kernel then sees 8 CPUs) w/ maxcpus=N (let's say N = 2), does that mean the kernel sees the first two 2 _real_ CPUs, or the first real CPU Hyperthreaded? I would think the first, but I'm curious and couldn't really find any solid information on it.
