Cover letter [PATCH -rt 0/5] hotplug fixes

Hi,

the following patches enable me to 'almost' build a kernel while hotplugging like crazy.

while :; do
echo 0 > /sys/devices/system/cpu/cpu1/online;
echo 1 > /sys/devices/system/cpu/cpu1/online;
done

vs

make -j5

There still seems to be a bit of weirdness left, but I throught it time to post these patches so that others can have a peek.
