Peter Wemm 194b08ffc3 Implement an optimization for INTREN/INTRDIS that bde pointed out last ... time I tinkered around here. Since INTREN is called from the interrupt critical path now, it should not be too expensive. In this case, we look at the bits being changed to decide which 8 bit IO port to write to rather than unconditionally writing to both. I could probably have gone further and only done the write if the bits actually changed, but that seemed overkill for the usual case in interrupt threads. [an outb is rather expensive when it has to cross the ISA bus]		2001-01-15 04:18:58 +00:00
