If I boot with: maxcpus=2 possible_cpus=4
I get
# grep . /sys/devices/system/cpu/cpu[0-9]*/online' /sys/devices/system/cpu/cpu1/online:1 /sys/devices/system/cpu/cpu2/online:1 /sys/devices/system/cpu/cpu3/online:1
When 2 and 3 *should* be offline. I also get -EINVAL if I try to re-offline them in this state. 2 and 3 don't show up in /proc/cpuinfo, so sysfs just looks broken here.
I'm bisecting it at the moment, but won't get to finish until tomorrow. Just thought I'd report early and often. :)
