I'm planning on making all the suggested fixes, but just to simplify 
things, here is the (small, obviously correct) change for GDT alignment 
that was the core motivation for this undertaking.  It would be 
extremely nice if this were headed for 2.6.15.  I want to get the 
cleanups in as well, but some of them should brew a bit more - 
especially, the kprobes fix needs some real rework and debate.

Is it worthwhile to even think about supporting kprobes on user code?  I 
would argue strongly no, that is the job of userspace, not the kernel.  
Kernel code is more precious and dangerous.
