Update of /b/source/CVS/src/sys/arch/i386/isa
In directory sun-lamp.cs.berkeley.edu:/d/users/mycroft/src/sys/arch/i386/isa

Modified Files:
	npx.c 
Log Message:
Since npxdna() and npxsave() are only ever called at spl0 now, we can get rid
of all the overhead of frobbing the IDT, and just use a simple flag to tell
npxintr() to ignore interrupts.  This allows lots of code reduction.
Also, update some comments and add some DIAGNOSTIC code to detect is these
assumptions ever become wrong.
