when flipping the code descriptors also update cs in the
tss and not only in the frame since we might be returning that way too.
add a heuristic for detecting an exec protection fault:
iff we get a read protection fault (which we normally never
get due to our segments being always readable) we assume that
it was an exec protection indeed and go to page fault
routine which will decide the rest for us (including sending
a signal should that be needed).
problem found by drahn@ and testing by many ppl.
