Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work. 2018-10-16 11:01:38 +02:00			`#pragma once`

Add a PIC::getISR() helper. 2018-10-17 16:53:06 +02:00			`#include <AK/Types.h>`

Make bash-2.05b build with minimal changes. This is really neat. :^) 2018-11-17 00:11:08 +01:00			`void enable(byte number);`
