mycroft ce7cc0c18a Move the `used fpu' flag into mdproc, so it can be referenced when a process

cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header

mycroft 35cdd801e6 Convert port, IRQ, and DRQ numbers to ints. 1994-11-18 21:57:40 +00:00
mycroft d254e95680 Garbage collect some variables which are no longer used. 1994-11-07 10:19:28 +00:00
mycroft d5f99262a9 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.

cgd 330f5907f2 say "using exception 16" rather than "exception 16"; the latter
