kernel-parameters.txt where we limit the number of present cpus to the
maxcpus cmdline but still show the possible cpus in sysfs although we
only allow hotplugging of the present cpus. So a maxcpus=1 on a system
with possibly 2 cpus will have a cpu1 in /sys/devices/system/cpu/ but
error out when you do

# echo 1 > /sys/devices/system/cpu/cpu1/online

because the cpu isn't present (to use the cpumask notation).
