It used to. 64-bit kernel used to handle maxcpus option as documented in the
Documentation/cpu-hotplug.txt and 32-bit one was broken.
I just looked at the latest code and realized that both are now broken. They
ignore cpu id > maxcpus instead of not-booting them.
I'll send a patch that fixes that tomorrow.
