History
Bruce Evans 50045fbc7c Changed the global `idt' from an array to a pointer so that npx.c 
automatically hacks on the active copy of the IDT if f00f_hack()
has changed it.  This also allows simplifications in setidt().
This fixes breakage of FP exception handling by rev.1.55 of
sys/kernel.h.  FP exceptions were sent to npx.c's probe handlers
because npx.c "restored" the old handlers to the wrong copy of the
IDT.  The SYSINIT for f00f_hack() was purposely run quite late to
avoid problems like this, but it is bogusly associated with the
SYSINIT for proc0 so it was moved with the latter.

Problem reported and fix tested by:  Martin Cracauer <cracauer@cons.org>
