vanishing ioctl handler debugging
We've had several reoprts of the CPU jumping to 0x00000000 is do_ioctl(). I
assume that there's a race and someone is zeroing out the ioctl handler while
this CPU waits for the lock_kernel().
The patch adds code to detect this, then emits stuff which will hopefuly lead
us to the culprit.
