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.

(patches against .24-rt)
