one problem was that the WORK_MASK definitions in thread_info.h were not
updated - neither the word-sized tests in entry.S. This meant we missed
delayed-preemption on return-from-kernel. But we've got one free bit in
the first by - bit 6, so i moved the DELAYED bit there. Another bug was
that the idle thread did not check for delayed preemption. I fixed these
in the -48-07 patch.
