Actually kernel threads can dynamically change to a different kstack
and allocate themselves a bigger one.. I forget where it is used but I
remember that htere is codde in exit to clean up teh extra kernel stack
if it is being used..

Is this running as  a kernel thread or on a user's kernel thread stack?
