logical processor number.
DESCRIPTION

IN THE SYSTEM
o Set ``default'' CPU width for trap handlers
o Enable FP coprocessor
REVISIT
this could be done in the ``code 22'' trap handler.
(frowands idea - that way we know which processes need FP
registers saved on the interrupt stack.)
NEWS FLASH
wide kernels need FP coprocessor enabled to handle
formatted printing of lx for example (double divides I think)
o Enable CPU profiling hooks.
